Spontaneous breaking of baryon number, baryogenesis and the bajoron
Pedro Bittar, Gustavo Burdman, Gabriel M. Salla
We explore the spontaneous breaking of global baryon number for baryogenesis. We introduce a model with three majorana fermions and a complex scalar carrying baryon number charge.…
Displaced vertex signals of low temperature baryogenesis
Pedro Bittar, Gustavo Burdman
We explore the connection of baryogenesis at temperatures below the electroweak scale and signals for long-lived particles at the LHC. The model features new SM singlets, with a lo…
Neutrino Masses in the Mirror Twin Higgs with Spontaneous Breaking
Pedro Bittar, Davi B. Costa, Gustavo Burdman
We introduce a mirror twin Higgs model with spontaneous symmetry breaking that ameliorates the constraints in twin Higgs cosmology and, at the same time, generates t…
Gravity-Induced Photon Interactions and Infrared Consistency in any Dimensions
Pedro Bittar, Sylvain Fichet, Lucas de Souza
We compute the four-photon () operators generated by loops of charged particles of spin , , in the presence of gravity and in any spacetime dimension .…
Baryogenesis and Dark Matter in the Mirror Twin Higgs
Pedro Bittar, Gustavo Burdman, Larissa Kiriliuk
We consider a natural asymmetric dark matter (ADM) model in the mirror twin Higgs (MTH). We show that it is possible to obtain the correct dark matter (DM) abundance when a twin ba…
Form Factors in Higgs Couplings from Physics Beyond the Standard Model
Pedro Bittar, Gustavo Burdman
We consider the momentum-dependent effects in Higgs couplings generated by physics beyond the standard model. We take a model-dependent approach, in which we can fully compute the…
