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 …

The violation of baryon number, $\mathcal {B} $, is an essential ingredient for the
preferential creation of matter over antimatter needed to account for the observed baryon …

New particles in theories beyond the standard model can manifest as stable relics that
interact strongly with visible matter and make up a small fraction of the total dark matter …

The neutron lifetime anomaly has been used to motivate the introduction of new physics with
hidden-sector particles coupled to baryon number, and on which neutron stars provide …

Proton decay, and the decay of nucleons in general, constitutes one of the most sensitive
probes of high-scale physics beyond the Standard Model. Most of the existing nucleon …

Nucleon decays are generic predictions of motivated theories, including those based on the
unification of forces and supersymmetry. We demonstrate that noncanonical nucleon decays …

The SuperKamiokande experiment tightly bounds the lifetimes of the baryon number-
violating proton decays. The decay widths for the nucleon to an antilepton and a photon are …

We employ the simplest possible models of scalar-fermion interactions that are consistent
with the gauge symmetries of the Standard Model and permit no proton decay to analyze the …

Proton decay in six-dimensions orbifolded on square T 2/Z 2 is highly suppressed at tree
level. This is because baryon number violating (BNV) operators containing only the zero …

A bstract In this paper we systematically consider the baryon (B) and lepton (L) number
violating dinucleon to dilepton decays (pp→ ℓ+ ℓ′+, pn→\({\mathrm {\ell}}^{+}\overline …
