# Electron-Neutrino Scattering a Strong Aspirant for Precision Measurements

## TL;DR

This paper investigates electron-neutrino scattering to improve precision in measurements, using both model-independent and model-dependent approaches to constrain new physics beyond the Standard Model.

## Contribution

It introduces a combined analysis of non-standard neutrino interactions and R-parity violating supersymmetry to set limits on new physics parameters from multiple experimental data sets.

## Key findings

- Identified allowed and forbidden regions for NSI and SUSY parameters.
- Established relationships between model-independent and model-dependent coupling parameters.
- Set new experimental limits on non-standard neutrino interactions and SUSY contributions.

## Abstract

This work focuses on the study of electron and neutrino scattering in the frame work of physics beyond the standard model (SM) called new physics (NP). Both Model Independent (MI) and Model Depen-dent (MD) ways are used to constrain NP. R-parity violating Supersymmetry ( /Rp SUSY) Model is used to perform MD analysis, where the scattering cross-section is infuenced by new s-bosons. For MI way non-standard neutrino intections (NSI) are used where there is no need of introducing any new particle. LSND and LAMPF-E225 data is used to identify the physically allowed and forbidden regions for nonunivarsal NSI parameters and nonunivarsal SUSY parameters. Similarly, CHARM-II, BNL-COL and BNL-E734 experimental is used to explore allowed and forbidden regions and limits are established. Furthermore, we establish a relationship between MI and MD coupling parameters.
