Given a Yukawa coupling as a function of scale and a vev, how can I compute the corresponding pole mas?
Understandably most paper explain how from a measured pole mass one can compute the running mass, for example, Eq. 19 here. However I want to compute the pole mass from the running mass. In...
Thanks for your answer. My question is motivated by the result that, assuming a fixed standard model vev, one has in SU(5) GUTs at high energies m_bottom=m_tau. However through the RGE running of the Yukawas one gets at low energies m_bottom=3 m_tau. The top mass in the article I cite above is...
Unfortunately, I have no good idea. Maybe, assuming it's metastable, i.e. with a long but not infinity lifetime, we could bring it to "rest" (cool it to a given temperature) and then sum the energy of the decay products?
Does it make sense to talk about the top mass at energies below mt, although in all processes the corresponding energy scale is above mt because of the rest mass energy of the top quark?
Using an effective field theory approach, the top quark decouples at energies below the top quark mass and...
