New Bounds On the Higgs Boson Mass
As the LHC continues to run at half power for the next year+, the US-based Tevatron continues to crank out results. Reader hweimer writes "Three new papers in Physical Review Letters present the latest results for the Higgs boson mass coming from Fermilab's Tevatron. The new data mandates that the Higgs boson mass within the standard model lies between 115 and 150 GeV." A year back we discussed the Tevatron's previous shrinking of the search space for the Higgs "God particle."
LOL!
From Wikipedia, 1 GeV/c^2 = 1.783 × 1027 kg . I wish summary articles were written so that most people could understand the terms used.
wasteful science at it's worst. trying to detect something we can't see, 99.999% (at least) of the worlds population wouldn't care if it was found and finding it would have zero impact on the worlds population. the world of physics and physicists needs to take a good long hard look at itself... and try and work out what it's going to do when the funding runs out... next year
The more I hear about Tevatron's new discoveries - and the slowing progress of the LHC; the more I think Fermilab had something to do with LHCs 'demise'
More power Egor, more power!!! Yes, Yeesssss. ****maniacal laughter***
Life is not for the lazy.
These are bounds for the mass of the Higgs boson assuming it exists. If it doesn't exist, this data is meaningless. What will presumably eventually happen is that we'll narrow the mass down to a very tiny bound (if it exists) which would be strong evidence for its existence. Or we might detect the Higgs boson using some other methods and higher energies, such as those at the LHC. Alternatively, if the Higgs boson doesn't exist then we may end up narrowing the upper and lower bounds until they cross each other. In that case the Standard Model will be wrong and we'll have an interesting day.
So much for Europe being the new frontier for science.
Oh well, I suppose we can always turn the LHC into an expensive underground parking for the Genevans...
500 park jobs per day at a cheap 10dollars an hour... with luck we'll have our money back somewhere around the year 7010...
but the tevatron does more at ten
Such idealism. Problem is, the young don't vote as much. They are also outnumbered by older people anyway. I don't see the democracies that support the collider dropping funding anytime soon. You'll grow up.
Or is it massive enough that it must purchase two seats?

No, it doesn't. Look at this graph. At a "3 sigma" level (and don't believe any new science that is not at the 3 sigma level or better), the mass of the Higgs (assuming it exists) is roughly between 115 and 225 GeV. To put it another way, a mass greater than the Tevatron exclusion zone at ~160 GeV is by no means ruled out.
How long will it take to realize that Aether theory had a lot of things right? I don't know much about anything, but I do have a feeling when things feel right. Up until Mr. Einstein, aether was it. The more I see the less I like, and I really wonder how long it will take before science realizes that we are, in fact, in the soup.
These Colliders will make some nice wind turbines once they are reprocessed. What goes around comes around.

I would imagine this is how my family and friends feel when I start speaking computer gibberish. I'd consider myself relatively competent to understand basic principles like gravity, mass, weight, etc, but can someone dumb this down?

I know that's probably a hopeless request without some sort of basis in this field, but can someone give the "particle physics for dummies" equivalent here?
I get the impression this is a hunt for some as yet unknown particle?
Troll? Seriously? It was a joke -- if you laughed then mod the guy funny, if not then leave him alone.

Determining the mass is fine, I guess, but what about size - is it bigger than a breadbox?

Anyone else read it that way?
From the spoils of war come tropheys, Mark my words, every single one of these colliders will be recycled and reprocessed into long term and far more useful gear like wind turbines. Lets consider the Niobium or Columbium used extensively in them. Remember who controls the science solar system and its definately not Physicists. For the unitelligent and poorly educated, "God" is and will always be the most intelligent lifeform on this planet not some Chinese Wisper collection of stories collected by warriors --> and today these poorly educated group of Disciples who have learned a Discipline in an artificially coined and extinct "universe" or University --> that means Catholic for you stupidly faithful. Like i said what goes around comes around, and Chemists or alchemists have already made a far more significant long term mark on these continually failing humans, for example uses of Chlorine ;)

115 GeV? Sounds like Fermilab is on half power too. When Europe gets there at full power, it will surely be 240 GeV. Ever heard of 'mains hum'?
The US-duhmerican's ego is apparently really hurt. How come every non-result of Fermilab is commented with some jingoistic bullshit. This is science, not some pissing contest, get over it. Only the unscientific morons at this site believe the detection Higgs-Boson is the main goal of LHC. You idiots know _nothing_ about how science works. Despicable.
I doubt any physicist would refer to the Higgs boson as "God particle" and that's obviously not the case in TFA. So why kdawson is feeding this idiotic meme ?
Next time we speak about serious science are we going to refer the research subject's as "pixie dust" or "Satan ichor" ?

Just released yesterday I think. Some cool new stuff discovered at the rhic at brookhaven national labs. http://www.bnl.gov/bnlweb/pubaf/pr/PR_display.asp?prID=1074 "“This research offers significant insight into the fundamental structure of matter and the early universe, highlighting the merits of long-term investment in large-scale, basic research programs at our national laboratories,” said Dr. William F. Brinkman, Director of the DOE Office of Science. “I commend the careful approach RHIC scientists have used to gather detailed evidence for their claim of creating a truly remarkable new form of matter.”"

You are right in the first part of that statement, the colliders are being recycled. However I am not aware of any being turned into wind turbines.
I know someone on the D0 group at Fermi, and was talking about collider fate with him recently. He pointed out that many of the facilities that are now serving as synchrotons (or high-energy light sources, such as Cornell's CHESS) which make significant contributions to structural biology. Currently we have less than 10 synchrotrons in the US - and many more structural biologists - so increasing that total can help a lot.
However your assertion of "far more useful gear" is a statement of opinion. High energy physics creates a lot of jobs, and a lot of valuable research for the public good.

The scientists are searching through a parking lot for a car that may or may not be there. The parking lot is 100ft tall and they have searched the lowest 60 feet of it. If the car exists and conforms to their understanding of what a car is then it will be found by searching the next 40 feet. However, they have ladders and the equipment to keep climbing past the top floor of the parking lot. If they find the car floating 30ft above the top floor of the parking lot they will have to redifine what a car is. Yes that's right, you heard it here first; The Higgs Boson = flying cars. Let's make it happen people.

Well ...
... maybe not.
Most people use the word "particle" to mean a small solid object, and I think it is fair to say that quarks, gluons, and the Higgs can't meaningfully be categorised in this way. It is not surprising that early mathematical physicists often emphasised concentrating on the wave equations and not trying to assign physical meanings.

Hello: Time for me to fight the LHC propaganda machine with my own efforts. The unified standard model doesn't need the Higgs mechanism. http://www.zazzle.com/the_stand_up_physicist_said_tshirt-235942932145293980

In fact, the definition of a field is something that assigns a value to every point in space. The EM field associated with a charged particle (which could be moving) assigns E and B vectors to every point in space, for example. You are probably thinking in terms of relativity, which involves the concepts of matter causing space-time to be curved. The trouble is that relativity needs to be reconciled with quantum mechanics - it doesn't give you any insight as to WHY there is gravity. The way to do that is by figuring out what causes gravitational fields, and the way to do that is to find the particle - Higgs - that mediates the field (in the same way that photons mediate the EM field). Space itself, though, isn't a field.
Seriously, the applications for a lot of this stuff doesn't become apparent until after it's been discovered, I'm not sure what people thought they'd be able to do with Maxwell's equations, but I doubt very much that they thought we'd get super colliders and computers out of it.
You just told the average idiot that the science they think is useless led to the invention of a giant money-wasting useless science machine, and a toy.
Here is the list of worthwhile results of science to the average moron:
Fire, as used in cooking
Paper, ink
Firearms
Automobiles
Cameras
Telephones
Computers (including gaming consoles), as used for facebooking, twittering, porn, gaming
Cell phones, particularly iPhones and Blackberries
Try to include some of these technologies into your justifications for scientific endeavors that don't yield immediate, tangible results. Be sure to mention some of them specifically, for example they won't understand integrated circuit -> microprocessor -> small computers -> iPhone.
So, to fix your statement for you:
Seriously, the applications for a lot of this stuff doesn't become apparent until after it's been discovered, I'm not sure what people thought they'd be able to do with Maxwell's equations, but I doubt very much that they thought we'd get (redacted) and Xbox360s, facebook, twitter, internet porn and iPhones out of it.

1) You can't get to absolute zero - to get something that cold would require you to chill it with something even colder, which is impossible by definition.
2) Even if you could get to absolute zero, all molecular motion doesn't stop - the particles still have what's called "zero-point" energy, which means they would still be moving a little. For them to be completely stopped would violate the uncertainty principle: you'd know their position and momentum exactly.
3) Obviously, just because things stop moving doesn't mean their mass disappears. Does your car become massless when you put it in your garage? For a photon, the concept of "rest mass" is pretty much purely a mathematical idea - they can't ever stop moving, so their rest mass is never directly in evidence.
... that the overall particle physics community is not real enthusiastic about the "God particle" terminology. There's nothing particularly "god-like" about it.
