kay-pee Posted January 12, 2007 Report Posted January 12, 2007 Some questions.What was the time of emergence of higgs ?:) Did it appeared at the same time bosons appeared ? Just after the quark-anti-quark era, can higgs appear ? how? These questions are riddling me and i want to get them solved . Quote
CraigD Posted January 12, 2007 Report Posted January 12, 2007 My comprehension of particle physics and the Big Bang isn’t adequate to this question, but taking wikipedia on partially-bind faith, the answer is, I think, that the Higgs boson appeared slightly later at 10^-12 s, than the gluon boson, which appeared at the same time as quarks, at 10^-33. (source: Wikipedia article “Timeline of the Big Bang”) Theory of this sort, beyond current experimental testability, leaves me with an uneasy feeling. I would not be surprised if much of it is wrong.

kay-pee Posted January 12, 2007 Author Report Posted January 12, 2007 Another one was with supersymmetery --The way they named superpartners was like that--Photons----photinoSame way----neutrons---neutrino...????? Quote
sanctus Posted January 15, 2007 Report Posted January 15, 2007 It was not the same way for neutrons and neutrinos.One reason is that the neutrino is a findamental particle and the neutron is a composite of the fundamental quark particles.So you have the electron and the selectron and I'm not sure but I would say you have the quark and the squark :D Quote
kay-pee Posted January 15, 2007 Author Report Posted January 15, 2007 I know that.... i just wanted to comment on the way they had named them....like-photon-photinosimilarly neutron's spartner will be neutrino Quote
Tormod Posted January 15, 2007 Report Posted January 15, 2007 similarly neutron's spartner will be neutrino Not really, the neutrino is actually a lepton in the standard model, not a supersymmetry partner of the neutron. Quote
kay-pee Posted January 18, 2007 Author Report Posted January 18, 2007 Their technique of naming doesn't apply everywhere.....! Quote
Qfwfq Posted January 23, 2007 Report Posted January 23, 2007 Such things can happen due to history, they couldn't always guess the best choice. For instance the term meson was coined for particles of mass intermediate between that of electrons and baryons. The muon was initially called a mu-meson but this turned out to be a rather unhappy choice. Quote
