      Disclaimer: I've been out of grad school way too long. So... hydrogen fusion occurs at "relatively" lower temperatures and pressures than in this quark experiment. The H-bomb uses heat and pressure (usually from a 'wrap' of fission bomb) to force protons and neutrons thru the repulsive barrier and create Helium nuclei.
      Knowing next to nothing about quark plasmas, I'd suspect the ridiculously short lifetime of these particles means the plasma re-coagulates into various elementary particles.

Fling them at each other at 99% the speed of light, and when they hit, all sorts of interesting things will go flying off in various directions. That's what happened in this experiment. Fusion is as irrelevant here as oxidation/reduction. The energy level is just far too enormous. What's interesting here is that something is absorbing some of the stuff that should be flying off in various directions, which means that they're creating something more dense than the stuff that's there to begin with.

      Well, for one thing, you haven't read the article well enough. At least one of the elements under test is gold, which is quite a ways on up the heavy end of the periodic table from iron. Iron is the point where the balance of matter in vs energy out reverses.

      I mention iron because when a star runs out of fuel, the star collapses until it has enough pressure and temperature to start the next fusion process, each one from the hydrogen->helium stage requireing more heat and pressure to maintain. Quite a few steps up the ladder it will finally get to making iron. I forget what out of unforch, I'm not a nuclear physicist.

      But theres a minor detail to making iron, and ALL the heavier elements by the fusion method, it takes more energy that it releases to make iron. At that point, the core cools, and can no longer support the rest of the star. More materiel falls into the core heating it back up again until the next reaction gets started, and the scenario repeats, this on a time scale considerably under a minute, and in fact limited by the local speed of sound which in ultradense material is a good fraction of C.

      Basicly the star collapses into itself, with 2 possible outcomes. Heavy stars can collapse into a neutron star and may well bounce a considerable portion of the fusion byproducts back out into space in the form of a super nova. The really heavy ones may even collapse to a black hole.

      The one that bounce are where ALL the iron and heavier elements come from, and a goodly share of the carbon we're made out of was once in the heart of an ageing star that went boom at the end of its life.

      What they are doing in the accelerator is creating a very unstable and short lived version of the core of a collapsing star at about the point of its bounce if it doesn't hit black hole density.

      This takes energy, huge amounts of it, most of which is absorbed. I would in fact be interested in finding out if the end product was still a gold ion when two of them meet at relativistic speeds.

      My guess is something heavier if it could be caught in sufficient quantities to analyze.

      OTOH, once the plasma cools a few femtoseconds, probably enough identifiable particles will be ejected, which is what they are actually looking at, and the end result might well be identifiably gold, but fewer of them than went in.

      Thats the problem with these little public announcements, they dumb the data down trying to make Joe Sixpack understand it, removing 95% of the usefull data that we might be able to add up and come to a conclusion.
