A simple extension of the minimal supersymmetric standard model in which baryon and lepton numbers are local gauge symmetries spontaneously broken at the supersymmetry scale is reported. This theory provides a natural explanation for proton stability. Despite violating R-parity, it contains a dark matter candidate carrying baryon number that can be searched for in direct detection experiments. The model accommodates a light active neutrino spectrum and predicts one heavy and two light sterile…

Gauge theory for baryon and lepton numbers with leptoquarks.
TLDR
New extensions of the standard model are found which predict the existence of fermions that carry both baryon and lepton numbers (i.e., leptoquarks) and the local baryonic and leptonic symmetries can be broken at a scale close to the electroweak scale.
Baryon and Lepton Number as Local Gauge Symmetries
We investigate a simple theory where Baryon number (B) and Le pton number (L) are local gauge symmetries. In this theory B and L are on the same footing and the anomalies re cancelled by adding a
Minimal theory for lepto-baryons
B and L at the supersymmetry scale, dark matter, and R-parity violation
We present a simple theory where baryon and lepton numbers are spontaneously broken at the supersymmetry scale. In this context R parity must be spontaneously broken but the theory still contains a

TLDR
A wider framework involving the existence of generations with exotic SU(2){sub {ital L}}{direct product}U(1){ sub {ital Y}} quantum numbers is considered, which allows us to derive a spectrum of fermions which contain the known quarks and leptons.
Naturally light sterile neutrinos from theory of R-parity
LSP Squark Decays at the LHC and the Neutrino Mass Hierarchy
The existence of R-parity in supersymmetric models can be naturally explained as being a discrete subgroup of gauged baryon minus lepton number (B L). The most minimal supersymmetric B L model
Gauge symmetries of electroweak interactions
By considering the symmetries associated with baryon number and lepton number conservation as gauge symmetries, the underlying gauge symmetry of weak electromagnetic interactions is shown to
Minimal gauged U(1) B-L model with spontaneous R parity violation.
TLDR
The minimal gauged U(1) B-L supersymmetric model is studied and it is shown that it provides an attractive theory for spontaneous R-parity violation and a consistent mechanism for generating neutrino masses and a realistic mass spectrum.
The minimal theory for R-parity violation at the LHC
A bstractWe investigate the simplest gauge theory for spontaneous R-parity breaking and its testability at the LHC. This theory, based on a local B-L gauge symmetry, can be considered as the simplest
