DESCRIPTION:Webinar from San Diego: The principle of minimal coupling has 
 been used in the study of Higgs boson interactions to argue that certain h
 igher dimensional operators in the low-energy effective theory generalizat
 ion of the Standard Model are suppressed by loop factors\, and thus smalle
 r than others. It also has been extensively used to analyze beyond-the-sta
 ndard-model theories. We show that in field theory\, and even in quantum m
 echanics\, the concept of minimal coupling is ill-defined and inapplicable
  as a general principle\, and give many pedagogical examples which illustr
 ate this fact. We also clarify some related misconceptions about the dynam
 ics of strongly coupled gauge theories. Many arguments in the literature o
 n Higgs boson interactions that use minimal coupling\, particularly in pse
 udo-Goldstone Higgs theories\, are inherently flawed.\n\nhttps://indico.if
