چکیده انگلیسی
We study the Î-resonance and deep inelastic scattering contributions in the tau-neutrino-nucleon scattering νÏ+NâÏâ+X and ν¯Ï+NâÏ++X in the presence of a charged Higgs and a Wâ² gauge boson. The new physics effects to the quasielastic process have been discussed in a previous work. The extractions of the atmospheric mixing angle θ23 rely on the standard model cross sections for νÏ+NâÏâ+X in Î½Ï appearance experiments. Corrections to the cross sections from the charged Higgs and Wâ² contributions modify the measured mixing angle. We include form factor effects in the new physics calculations and find the deviations of the mixing angle. If high-energy Long Base Line experiments are designed to measure θ13 through tau-neutrino appearance, the new physics effects to νÏ+NâÏâ+X and ν¯Ï+NâÏ++X can impact the extraction of this mixing angle. Finally, we investigate the new physics effects on the polarization of the Ïâ leptons produced in νÏ(ν¯Ï)-nucleon scattering.
