‘Exotic vector-like pair’ of color-triplet scalars

‘Exotic vector-like pair’ of color-triplet scalars

We propose a minimal extension of Standard Model, generating a Majorana mass for neutron, connected with a mechanism of Post-Sphaleron Baryogenesis. We consider an 'exotic vector-like pair' of color-triplet scalars, an extra Majorana fermion ψ, and a scalar field ϕ, giving mass to ψ. The vector-like pair is defined 'exotic' …
