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 .…

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…
