A reappraisal of constraints on models from unitarity and direct searches at the LHC
Triparno Bandyopadhyay, Gautam Bhattacharyya, Dipankar Das +1
In a truly model-independent approach, we reexamine a minimal extension of the Standard Model (SM) through the introduction of an additional symmetry leading to a new neutra…
Three-Higgs-doublet model under A4 symmetry implies alignment
Soumita Pramanick, Amitava Raychaudhuri
A model with three scalar doublets can be conveniently accommodated within an A4 symmetric framework. The A4 symmetry permits only a restricted form for the scalar potential. We sh…
Left-right model with TeV fermionic dark matter and unification
Triparno Bandyopadhyay, Amitava Raychaudhuri
The ingredients for a model with a TeV right-handed scale, gauge coupling unification, and suitable dark matter candidates lie at the heart of left-right symmetry with broken D-par…
A neutrino mass model with S3 symmetry and see-saw interplay
Soumita Pramanick, Amitava Raychaudhuri
We develop a see-saw model for neutrino masses and mixing with an S3\times Z3 symmetry. It involves an interplay of Type-I and Type-II see-saw contributions of which the former is…
Obstacles to extending R-parity violation to Supersymmetric SU(5)
Najimuddin Khan, Subhendu Rakshit, Amitava Raychaudhuri
We explore the consequences of promoting bilinear R-parity violation, usually formulated in the minimal supersymmetric standard model framework, to a supersymmetric SU(5) grand uni…
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…
