Implications of the CMS search for W_R on Grand Unification
Triparno Bandyopadhyay, Biswajoy Brahmachari, Amitava Raychaudhuri
The CMS experiment at the Large Hadron Collider has reported a 2.8 excess in the channel around 2.1 TeV. Interpretation of this data is reconsidered in terms of th…
Kinetic mixing and symmetry breaking dependent interactions of the dark photon
Biswajoy Brahmachari, Amitava Raychaudhuri
We examine spontaneous symmetry breaking of a renormalisable U(1) x U(1) gauge theory coupled to fermions when kinetic mixing is present. We do not assume that the kinetic mixing p…
Testable constraint on near-tribimaximal neutrino mixing
Biswajoy Brahmachari, Probir Roy
General lowest order perturbations to hermitian squared mass matrices of leptons are considered away from the tribimaximal (TBM) limit in which a weak flavor basis with mass diagon…
Constrained analytical interrelations in neutrino mixing
Biswajoy Brahmachari, Probir Roy
Hermitian squared mass matrices of charged leptons and light neutrinos in the flavor basis are studied under general additive lowest order perturbations away from the tribimaximal…
Perturbative generation of theta_{13} from tribimaximal neutrino mixing
Biswajoy Brahmachari, Amitava Raychaudhuri
Solar and atmospheric neutrino oscillations are consistent with a tribimaximal form of the mixing matrix of the lepton sector. Exact tribimaximal mixing leads to . Re…
Orbifold GUT model with nine Higgs doublets
Biswajoy Brahmachari
We describe a non-supersymmetric orbifold GUT based on SU(5) symmetry. It is a modification of Kawamura's 5-D orbifold GUT model. The difference lies in the choice of Higgs scalars…
