Identification of Sneutrino s-Channel Exchange Signatures in R-Parity Violating SUSY at a Linear Collider with Polarized Beams

Abstract

We study the possibility of uniquely identifying the indirect effects of s-channel sneu-trino exchange predicted by supersymmetric theories with R-parity violation against other new physics scenarios in process e+e− → µ+µ− at the International Linear Collider. These competitive models are interactions based on four-fermion contact interactions, unparticles, gravity in large and in TeV-scale extra dimensions, anomalous gauge couplings and Z' vector bosons. We use a double polarization asymmetry to evaluate the identification reach on sneutrino exchange. The availability of polarized beams plays a crucial role in identifying s-channel sneutrino exchange signature.
