“…Albright and Jarlskog, in Ref. [16], pointed out that there are two additional structure functions, F 4 and F 5 that contribute to the tau neutrino cross section. F 4 and F 5 are ignored in muon neutrino interactions because of a suppression factor depending on the square of the charged lepton mass (m ℓ ) divided by the nucleon mass times neutrino energy, m 2 ℓ /(M N E ν ).…”

The ν µ → ν τ oscillation hypothesis will be tested through ν τ production of τ in underground neutrino telescopes as well as long-baseline experiments. We provide the full QCD framework for the evaluation of tau neutrino deep inelastic charged current (CC) cross sections, including next-leading-order (NLO) corrections, charm production, tau threshold, and target mass effects in the collinear approximation. We investigate the violation of the Albright-Jarlskog relations for the structure functions F 4,5 which occur only in heavy lepton (τ ) scattering. Integrated CC cross sections are evaluated naively over the full phase space and with the inclusion of DIS kinematic cuts. Uncertainties in our evaluation based on scale dependence, PDF errors and the interplay between kinematic and dynamical power corrections are discussed and/or quantified.

“…In the case of tau neutrino-matter interaction the produced lepton has short lifetime, so only its decay products can be observed. The large mass of the tau in contrast to electron and muon implies that it can be partially polarized [2,3]. The degree of polarization of tau is one of the parameters which describe its decay products distributions [4,5].…”

The quasielastic charged-current (CC) tau neutrino (antineutrino)-nucleus scattering is considered. The dependence of tau polarization on nuclear-structure effects is discussed in detail. The description of the nucleus is based on the Mean-Field Theory (MFT). The ground state of nucleus is described using the Relativistic Fermi Gas model (FG). The effective mass is introduced as well as the ring Random Phase Approximation (RPA) effects are taken into account in the framework of relativistic meson-nucleon model. The Local Density Approximation (LDA) is used for the argon nucleus, having in mind possible application to the ICARUS experiment. The discussion concentrates on the threshold region where the τ − can be unpolarized and the nuclear effects play an important role.

“…neutrino interactions without neglect of the lepton mass were first published in [5] (see also [6]). However, they were written in terms of the scaling functions F ′ i s and no connection was given with the basic quark/antiquark densities given by the available structure functions library packages.…”
