ev->ev Aspirant for New Physics

Abstract

This work focuses on the topical survey of precision measurements via ev->ev scattering in the frame work of Non-Standard Interaction (NSI). Both Model Independent (MI) and Model Dependent (MD) are used in addition the Standard Model (SM). R-parity violating Supersymmetry (SUSY) Model is used to perform MD analysis, where the scattering cross-section is influenced by new S-bosons. By using LSND experimental value, we obtain limits for SUSY coupling parameter (lambda) and obtain physically allowed and disallowed regions rather than just limits/bounds for MI paramters. Under the limits of CHARMII, BNL-COL and BNL-E734 experimental values, we get physically allowed and disallowed regions for MI and MD couplings parameters. Sensitivity of these coupling parameters with each other is also discussed. Furthermore, we establish a relation between MI coupling parameters and R-parity violating SUSY Model coupling parameters.Comment: 14 pages, 15 figure
