Abstract
We discuss how to calculate cross sections as well as rapidity, transverse momentum and energy distributions of ντ and \( {\overline{\nu}}_{\tau } \) produced from the direct \( {D}_s^{\pm}\to {\nu}_{\tau }/{\overline{\nu}}_{\tau } \) and chain \( {D}_s^{\pm}\to {\tau}^{+}/{\tau}^{-}\to {\nu}_{\tau }/{\overline{\nu}}_{\tau } \) decays in p+96 Mo scattering with proton beam Elab = 400 GeV i.e. at \( {\sqrt{s}}_{NN} \) = 27.4 GeV. The τ decays are simulated with the help of the Tauola code and include multiple decay channels of τ in amounts proportional to their branching ratios. In our calculations we include \( {D}_s^{\pm } \) from charm fragmentation c →\( {D}_s^{+} \) and \( \overline{c}\to {D}_s^{-} \) as well as those from subleading fragmentation of strange quarks/antiquarks s →\( {D}_s^{-} \) and \( \overline{s}\to {D}_s^{+} \). The \( s\ne \overline{s} \) asymmetry of the strange quark content of proton is included. The different contributions to \( {D}_s^{+} \) and \( {\nu}_{\tau }/{\overline{\nu}}_{\tau } \) are shown explicitly. We discuss and quantify a not discussed so far effect of asymmetries for production of ντ and \( {\overline{\nu}}_{\tau } \) caused by subleading fragmentation mechanism and discuss related uncertainties. A potential measurement of the asymmetry is discussed. Estimates of a number of observed \( {\nu}_{\tau }/{\overline{\nu}}_{\tau } \) in the \( {\nu}_{\tau }/{\overline{\nu}}_{\tau } \) +208Pb reaction, with 2m long target are given with the help of the NuWro program. We refer also to the production of the high-energy (anti)neutrinos in the atmosphere.
