Quasiparticles, more energy in the lhc than expected?
Posted: Wed Apr 28, 2010 7:35 am
For the last few topics things started to drift in the direction of BEC and other questions after this type of discussion (link):
For instance in regard to the quoted discussion above, a 'phonon' moves at the speed of sound, and in the case of BEC light passing through can be slowed down to a few meters per second.
How can we know that after a colision, all energy is gone before the next one happens, and if there isn't such a thing as an energy wind/waves exciting surrounding matter more and more, like rotating windmills or flapping flags.

flapping flags remain mystery
Many "simple" things are fraught with mystery. Consider a flag: Why does it flap, instead of streaming straight in a steady breeze? Five centuries after the Scientific Revolution swept the Western world, scientists surely can explain the flapping of flags, right? No, they can't -- not yet. But they're working on it. Flag-flapping poses one of "the essential difficulties of the general problem of elastohydrodynamics".

I know the analogy looks stupid, but the question is how rigid are atoms within a luminosity storm of particles?
So what about phonon-wind or other Quasiparticles in the lhc? Could they charge matter more than expected, do they stay unnoticed by the detectors, and move through a vacuum as we know it? btw there is a whole list of them.Mailo wrote:I know how fast ionization recombines. I know how fast the created particles are. I know the collision happens in a better vacuum than outer space and the created particles rapidly spread out from there. When they encounter matter (e.g. detectors) they are already well separated and do not interact with each other.Chelle wrote:That is something you asume, how do you know?Mailo wrote:When the next collision happens, all effects of the previous one are gone.
