  Neutrino oscillation parameters can be understood in a better way by building
a more complete picture of neutrino interactions. This poses a series of
important theoretical and experimental challenges because of the elusive nature
of neutrino and an inherent difficulty in its detection. This work is an
attempt to study neutrino interactions through a purely theoretical approach
using fluctuation theory. Though experiments are trying hard to shed more light
on neutrino interactions, our knowledge of neutrino oscillation parameters is
not precise at different energy levels. In this context, one cannot help but
give a bold try to marvel at how far our theoretical frameworks can extend.
