DESCRIPTION:Speakers: Sergio Ferrando Solera (IFIC)\nDimensional regulariz
 ation is nowadays the most used technique to perform loop calculations in 
 Quantum Field Theories. However\, it faces some complications when applied
  to chiral gauge theories such as the Standard Model of particle physics b
 ecause it is not possible to define a mathematically consistent D-dimensio
 nal scheme that preserves gauge symmetries. Nonetheless\, for a theory fre
 e of physical anomalies it is always possible to restore the symmetry by t
 he addition of the appropriate set of both infinite and finite counterterm
 s. In our work\, we present the complete calculation of such finite counte
 rterms needed for the consistent renormalization of the dimension six four
 -fermion operators of the Standard Model Effective Field Theory at one loo
 p using the Breitenlohner-Maison-’t Hooft-Veltman scheme.\n\nhttps://ind
