Global fits and the search for new physics: past, present and future

Peter Athron, Csaba Balázs, Jon Butterworth +15

In this work, we review the history and current role of global fits in the search for physics beyond the Standard Model~(BSM), including precision tests of the Standard Model (SM).…

Constraints from muon $g - 2$ on a gauged non-universal $U (1)_{X}$ model with inverse see-saw neutrinos

J. S. Alvarado, R. Martinez, Cristian Sierra

We study the effects on a non-universal $U (1)_{X}$ extension of the Standard Model given the alternative value obtained by the Budapest-Marseille-Wuppertal (BMW) group for the anom…

Electroweak baryogenesis from charged current anomalies in $B$ meson decays

Peter Athron, Michael J. Ramsey-Musolf, Cristian Sierra +1

We demonstrate for the first time that new physics explaining the long standing charged $B$ meson anomalies, $R (D^{(*)})$ , can be the source of CP violation that explains the obser…
