Two-loop renormalization of general bosonic effective field theories
Guilherme Guedes, Jasper Roosmale Nepveu
The renormalization of higher-dimensional operators in quantum field theory is essential for phenomenological analyses in particle physics, and plays a significant role in the stud…

Small instanton-induced flavor invariants and the axion potential
Ravneet Bedi, Tony Gherghetta, Christophe Grojean +3
Small instantons which increase the axion mass due to an appropriate modification of QCD at a UV scale , can also enhance the effect of CP-violating operators to shift…

A log story short: running contributions to radiative Higgs decays in the SMEFT
Christophe Grojean, Guilherme Guedes, Jasper Roosmale Nepveu +1
We investigate the renormalization of the radiative decays of the Higgs to two gauge bosons in the Standard Model Effective Field Theory at mass dimension eight. Given that these a…
