Proton stability in grand unified theories, in strings and in branes
Abstract 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 unified models,Expand

DUSEL Theory White Paper
The scientific case for a Deep Underground Science and Engineering Laboratory [DUSEL] located at the Homestake mine in Lead, South Dakota is exceptional. The site of this future laboratory alreadyExpand

Fundamental Physics at the Intensity Frontier
Particle physics aims to understand the universe around us. The Standard Model of particle physics describes the basic structure of matter and forces, to the extent we have been able to probe thusExpand

Fate of R parity
The possible origin of the R-parity-violating interactions in the minimal supersymmetric standard model and its connection to the radiative symmetry-breaking mechanism is investigated in the contextExpand

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 aExpand

On the Origin of Neutrino Masses
We discuss the simplest mechanisms for generating neutrino masses at tree level and one loop level. We find a significant number of new possibilities where one can generate neutrino masses at theExpand

Renormalizable adjoint SU(5)
Abstract We investigate the possibility to find the simplest renormalizable grand unified theory based on the SU ( 5 ) gauge symmetry. We find that it is possible to generate all fermion masses withExpand

Triplet Scalars and Dark Matter at the LHC
We investigate the predictions of a simple extension of the standard model where the Higgs sector is composed of one SU(2)L doublet and one real triplet. We discuss the general features of the model,Expand

Neutrino masses and the CERN LHC: Testing the type II seesaw mechanism
We demonstrate how to systematically test a well-motivated mechanism for neutrino mass generation (type II seesaw) at the LHC, in which a Higgs triplet is introduced. In the optimistic scenarios withExpand
