  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.
