Disentangling SMEFT operators with future low-energy PVES experiments
Radja Boughezal, Frank Petriello, Daniel Wiegand
We study the potential of future Parity-Violating Electron Scattering (PVES) data to probe the parameter space of the Standard Model Effective Field Theory (SMEFT). We contrast the…
Four-lepton Z-boson decay constraints on the SMEFT
Radja Boughezal, Chien-Yi Chen, Frank Petriello +1
We discuss how four-lepton decays of the Z-boson probe currently unconstrained flat directions in the parameter space of the Standard Model Effective Field Theory (SMEFT). We deriv…
TVID 2: Evaluation of planar-type three-loop self-energy integrals with arbitrary masses
Stefan Bauberger, Ayres Freitas, Daniel Wiegand
We present TVID 2, a program to numerically evaluate an important class of planar three-loop self-energy master integrals with arbitrary masses. As with the predecessor version (TV…
Top quark decay at next-to-leading order in the Standard Model Effective Field Theory
Radja Boughezal, Chien-Yi Chen, Frank Petriello +1
We consider top quark decay in the Standard Model Effective Field Theory (SMEFT). We present a calculation of the total decay width and the -boson helicity fractions at next-to-…
Renormalization and ultraviolet sensitivity of gauge vertices in universal extra dimensions
Ayres Freitas, Daniel Wiegand
When computing radiative corrections in models with compactified extra dimen- sions, one has to sum over the entire tower of Kaluza-Klein excitations inside the loops. The loop cor…
