Although the origin of matter-antimatter asymmetry remains unknown, continuing advances
in theory and improved experimental limits have ruled out some scenarios for baryogenesis …

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 …

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 …

Supersymmetric extensions of the Standard Model that incorporate the axion solution to the
strong CP problem necessarily contain also the axino, the fermionic partner of the axion. In …

In models of baryogenesis based on grand unified theories (GUTs), the baryon asymmetry of
the Universe is generated through the CP and baryon number violating, out-of-equilibrium …

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 …

In a previous paper, referred to as a “Mini-Landscape” search, we explored a “fertile patch”
of the heterotic landscape based on a Z 6-II orbifold with SO (10) and E 6 local grand unified …

Abstract In simple SO (10) SUSY GUTs the top, bottom and tau Yukawa couplings unify at
the GUT scale. A naive renormalization group analysis, neglecting weak scale threshold …

We use $ t, b,\tau $ Yukawa unification to constrain SUSY parameter space. We find a
narrow region survives for $\mu> 0$(suggested by\bsgam and the anomalous magnetic …

We construct and discuss a “realistic” example of SUSY SU (5) GUT model, with an
additional U (1) flavour symmetry, that is not plagued by the need for large fine tunings, like …
