New Strange Asymmetry Results from NuTeV

Abstract

Results from the next to leading order (NLO) dimuon analysis from the NuTeV experiment at FNAL are presented. Charged current interactions in neutrino-nucleon scattering with two oppositely charged muons in the final state allow direct study of charm production and measurement of the strange sea. NuTeV's sign selected beam gives it the ability to extract the strange and antistrange seas independently, for which an asymmetry has been predicted in some theoretical models, and which is currently of intense interest in interpreting neutrino electroweak results. The dimuon results presented here represent the first analysis of dimuon events performed utilizing DISCO, a fully NLO cross section code differential in all variables required to model detector acceptance.
