Increasingly stringent limits from LHC searches for new physics, coupled with lack of
convincing signals of weakly interacting massive particle (WIMP) in dark matter searches …

A broad overview of the current status of proton stability in unified models of particle
interactions is given which includes non-supersymmetric unification, SUSY and SUGRA …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

We show that dark matter could be made of massive gauge bosons whose stability doesn't
require to impose by hand any discrete or global symmetry. Stability of gauge bosons can be …

Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

We present the minimal supersymmetric standard model with general broken R parity,
focusing on minimal supergravity (MSUGRA). We discuss the origins of lepton number …

We show that the minimal renormalizable supersymmetric SO (10) GUT with the usual three
generations of spinors has a Higgs sector consisting only of a “light” 10 dimensional and …

Experimentally, baryon number minus lepton number, BL, appears to be a good global
symmetry of nature. We explore the consequences of the existence of gauge-singlet scalar …

We study the minimal gauged U (1) BL supersymmetric model and show that it provides an
attractive theory for spontaneous R-parity violation. Both U (1) BL and R parity are broken by …
