Rejoice-The Higgs Potential as a function of temperature (T) •In QFT, temperature changes the vacuum •Nature chooses the vacuum that is (1) a global min. & (2) stable •At high T (e.g. Big Bang), the Higgs will want to be at h=0 at which point all particles become massless!pic.twitter.com/UGMRAfJGcL

is this like a ‘renormalization of couplings changes the potential shape at high energies’ kind of thing? or like a ‘potential shape feels different to hot states because bump is small wrt relevant fluctuation scales’ kind of thing? something else entirely?

You can think of the temperature as inducing effective (temperature dependent) operators in the 1PI effective action

thanks! and regarding stability, do you have any thoughts on the apparent higgs metastability? some possible selection mechanism? plain bad luck?

I don’t have any deep thoughts about it, no.. I haven’t thought about it very carefully
