DESCRIPTION:Speakers: Maria Cristina Fiore (Universidad de Granada)\nWe pe
 rform dimensional reduction of the electroweak sector of the dimension-six
  SMEFT to order $\\mathcal{O}(g^4)$ in coupling constants $g$. This analys
 is includes one-loop contributions to kinetic terms and quartic couplings\
 ; as well as two-loop contributions\, where operators such as four-fermion
  interactions first appear\, to squared mass terms. Using lattice data\, w
 e also provide evidence that\, in contrast with previous statements in the
  literature\, the SMEFT may undergo a first-order electroweak phase transi
 tion even without significant direct modifications of the Higgs potential 
 at zero temperature.\n\nhttps://indico.ific.uv.es/event/8035/contributions
