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…
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…
Rho Parameter Constraints on Models with Large Compact Dimensions
Prasanta Das, Sreerup Raychaudhuri
In models with large extra dimensions, where quantum gravity effects become strong at the TeV scale, the rho-parameter can receive large contributions from one-loop diagrams involv…
Trilinear R-Parity Violation: Theory to Experiment
Sreerup Raychaudhuri
Supersymmetric models without conservation of R-parity are reviewed and low-energy constraints on the extra trilinear couplings listed. Current searches at the LEP, Tevatron and HE…
Constraining Large Extra Dimensions Using Dilepton Data from the Tevatron Collider
Ambreesh K. Gupta, Naba K. Mondal, Sreerup Raychaudhuri
We use the invariant mass distribution of Drell-Yan dileptons as measured by the CDF and D0 Collaborations at the Fermilab Tevatron and make a careful analysis to constrain Kaluza-…
