SUMMARY:Vacuum stability and phase transitions: A rich source for fascinat
 ing math\, physics and phenomenology - Jose Eliel Camargo-Molina (Imperial
  College London)
DTSTART:20191031T160000Z

UID:TALK130021@talks.cam.ac.uk
CONTACT:Joseph Davighi
DESCRIPTION:In this talk I will approach the subject of vacuum stability f
 rom three different perspectives: Setting constraints in theories with man
 y scalars\, systematizing vacuum stability studies of generic models and t
 he details of using phase transitions in the early universe as a phenomeno
 logical test. After setting up the basics of vacuum decay and why it matte
 rs as a phenomenological test of BSM theories\, I will introduce the new v
 ersion of Vevacious (a code tackling the whole pipeline from Lagrangian to
  estimation of vacuum decay rates)  and how it is being used alongside cut
 ting-edge global fits with the GAMBIT framework. Lastly I will talk about 
 how phase transitions can also lead to phenomenological tests of inflation
 ary and cosmology models with an overview of the current state-of-the-art\
 , including the current open questions I find most interesting and crucial
 .
