Charmless non-leptonic decay with a tensor meson in the final state: A Probe to New Physics
Prasanta Kumar Das
This paper has been withdrawn by the author due to the following reason. One of his(author) collaborator rightly claims that the idea of this work belongs not from the author, but…
Higgs pair production due to a radion resonance in Randall-Sundrum model: prospects at the Large Hadron Collider
Prasanta Kumar Das, Biswarup Mukhopadhyaya
We consider Higgs pair production at the Large Hadron Collider (LHC) in a Randall-Sundrum scenario containing a radion field. It is shown that the enhanced effective coupling of th…
Torsion contraints from the recent precision measurement of the muon anomaly
Prasanta Das, Uma Mahanta, Sreerup Raychaudhuri
In this paper we consider non-minimal couplings of the Standard Model fermions to the vector (trace) and axial vector (pseudo-trace) components of the torsion tensor. We then evalu…
Tadpole diagrams due to KK modes of graviton and radion do not contribute to the parameter
Prasanta Das, Uma Mahanta
In this brief report we show that tadpole diagrams due to KK modes of the graviton and radion do not contribute to the vectorial isospin breaking parameter. Our result is fairl…
Constraints on radion vev from the beta functions for top yukawa coupling and higgs self coupling in the Randall-Sundrum model
Prasanta Das, Uma Mahanta
In this paper we determine how the beta function for the top Yukawa coupling to one loop is modified by a light stabilized radion in the Randall-Sundrum model. We then use this bet…
Anomalous Magnetic Moment of the Muon in a Composite Model
Prasanta Das, Santosh Kumar Rai, Sreerup Raychaudhuri
We make a fresh evaluation of contributions to (g-2) of the muon in the framework of a preonic model with coloured vectorlike leptons and heavy coloured Z bosons and discuss their…
