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…
