Updated Collider Bounds on the Parameters of Dynamical Torsion
Uma Mahanta, Sreerup Raychaudhuri
We constrain the parameters of dynamical torsion, namely, the torsion-fermion coupling and the torsion mass, by making a careful analysis of current LEP-2 data at several energies,…
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…
Quantum effects of compactified AdS_5 geometry on the higgs potential
Uma Mahanta
In this paper we determine the one loop radiative correction to the higgs potential due to quantum fluctuations about the background metric of Randall-Sundrum model. We then examin…
New Physics, precision electroweak data and an upper bound on higgs mass
Uma Mahanta
In this paper we express the effect of new physics on gauge boson self energy corrections through non-renormalizable dimension six operators. Using the precision electroweak data w…
