Light particles with baryon and lepton numbers
We consider light new particles χ and ϕ that carry baryon and lepton numbers. If these particles are lighter than nucleons they lead to exotic decays such as p→π+χ and p→e+ϕ, not yet fully constrained by dedicated searches. For χ and ϕ masses in the GeV range, proton decays are kinematically forbidd...
