Lepton Universality In Question, a Standard Model Assumption
Charliemopps writes: "Over the past few years, more and more experiments have started to question one of the core assumptions of the standard model: Lepton Universality. Simply put, the weak nuclear force is assumed to work equally on all Leptons (electron, muon and tau). Two years ago The Babar experimental collaboration reported that measurements indicated this may not have been the case. But the measurements were not accurate enough to be definitive.
Now, a report from The LHC shows that they have analyzed their entire dataset of proton-proton collisions and found a rather large discrepancy. These measurements are still not all that accurate. These decays happen so rarely that even with this huge data set there is still about a 1% change they are incorrect. One explanation for such measurements is an as-yet-undiscovered, charged Higgs particle. It would have to be extremely heavy: greater than 109GeV possibly even as high as 150GeV. This is predicted by some models outside of the Standard Model, like Supersymmetry."

To "fix" it, just add one or more of the following to the model:
* More turtles
* More nested epicycles
* More dimensions
* Invent dark [something] to plug it
* Say God did it
Profit!

Except that that LHC's ongoing failure to find any SUSY particles is making it increasingly unlikely Supersymmetry is right either:

With regards to Supersymmetry I have the feeling the LHC is going to end up being this century's version of Michelson-Morley.
However, given what happened after Michelson-Morley, we may be in for some very exciting new physics in the years to come if we can disprove Supersymmetry.
(At least I hope we are... :-))
Consider how long it took to gather enough of the right events to be reasonably certain about the Higgs, the various false alarms that vanished as more data was collected, etc. Another version just a bit rarer could easily be lost in the noise. Or the two could be similar enough that their signals aren't distinguishable from each other yet.
Wan't the confirmation just slightly different from what they expected.
The deviation might actually be traces of this unknown 2nd Higgs particle.
---- Sig. gone.
The standard model is an extremely comprehensive collection of theories that makes incredibly accurate predictions. It's a crappy computational tool. It's so computationally intractable that it requires supercomputers to simulate even simple multi-particle systems.
And that's the problem with applying pop logic to a fuzzy understanding of a vastly simplified description.
Modern quantum theory suggests not only that two examples of the same type of particle are not only completely identical except for certain features like position, but that even talking about particles as if they had individual existence doesn't really make sense.
When I grow up I'm going to Lepton University!
No wait...

Sounds like the simulation we are living in uses some de-duplication in the file system.to save space.
