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 particular, such an agreement is related to the use of the massive NNLO corrections for the NC heavy-quark production, along with the MS definition of the heavy-quark masses [21,22]. Instead, the CC DIS heavy-quark production has been described in the ABM12 fit with account of the NLO corrections [23][24][25] only. As a matter of fact, this approximation is adequate for the description of existing CC HERA data, in view of their relatively poor accuracy.…”

Determination of strange sea quark distributions from fixed-target and collider data

et al. 2015

We present an improved determination of the strange sea distribution in the nucleon with constraints coming from the recent charm production data in neutrino-nucleon deep-inelastic scattering by the NOMAD and CHORUS experiments and from charged current inclusive deep-inelastic scattering at HERA. We demonstrate that the results are consistent with the data from the ATLAS and the CMS experiments on the associated production of W AE -bosons with c-quarks. We also discuss issues related to the recent strange sea determination by the ATLAS experiment using LHC collider data.

We study soft-gluon radiation for heavy quark production in charged-current Deep Inelastic Scattering processes. We resum large-x contributions to the MS coefficient function to next-to-leading logarithmic accuracy and present results for charm quark structure functions for several values of the ratio m c /Q. The effect of soft resummation turns out to be visible, especially at small Q 2 , and the results exhibit very little dependence on factorization and renormalization scales. The impact of our calculation on structure function measurements at NuTeV and HERA experiments is discussed.
