  We propose a scenario for realizing inflation in the framework of
supersymmetric B-L extension of the Standard Model. We find that one of the
associated right-handed sneutrinos (the superpartner of the Standard Model
singlet fermion) can provide a new non-trivial inflationary trajectory at tree
level (therefore breaking B-L during inflation). As soon as the inflation ends,
the right-handed sneutrino falls into the supersymmetric vacuum, with a
vanishing vacuum expectation value, so that B-L symmetry is restored. In this
class of models, the B-L gauge symmetry will be radiatively broken at a TeV
scale and light neutrino masses are generated through the inverse seesaw
mechanism.
