Neutrino-nucleon cross section in ultra high energy regime

Abstract

Neutrino Physics is nowentering precision era and neutrino-nucleon cross sections are an important ingredient in all neutrino oscillation experiments. Specially, precise knowledge of neutrino-nucleon cross sections in Ultra High Energy (UHE) regime (TeV-PeV) is becoming more important now, as several experiments worldwide are going to observe processes involving such UHE neutrinos. In this work, we present new results on neutrino-nucleon cross-sections in this UHE regime, using QCD.
