Scotogenic mechanism from an extended $SU (2)_{1} \times SU (2)_{2} \times U (1)_{Y}$ electroweak symmetry

Julio Leite, Javier Perez-Soler, Avelino Vicente

We propose an extension of the electroweak sector of the Standard Model in which the gauge group $S U (2)_{L}$ is promoted to $S U (2)_{1} \times S U (2)_{2}$ . This framework naturally include…

QCD axion, colour-mediated neutrino masses, and $B^{+} \to K^{+} + E_{miss}$ anomaly

Chandan Hati, Julio Leite, Newton Nath +1

Motivated by the recent Belle II result indicating a $2.7 I ¨ $ excess of $B^{+} \to K^{+} + E_{miss}$ events compared to the Standard Model (SM) prediction for $B^+ \to K^+ Î½\ba…

Seesaw Limit of the Nelson-Barr Mechanism

A. L. Cherchiglia, A. G. Dias, J. Leite +1

We investigate how the solution to the strong CP problem and the explanation for the observed fermion mass hierarchies can be intrinsically related. Specifically, we explore the Ne…
