论文摘要
我们讨论了$ν_τ$和$ {\ edlineν}_τ$从直接$ d_s^{\ pm} \到ν_τ/{\ overline c $d_τ$和链$ d_s^{ $ p \！+^{96} \！\ mathrm {mo} $用质子梁$ e _ {\ mathrm {lab}} $ = 400 gev \ textit { In our calculations we include $D_s^{\pm}$ from charm fragmentation $c \to D_s^{+}$ and $\bar c \to D_s^-$ as well as those from subleading fragmentation of strange quarks/antiquarks $s \to D_s^-$ and $\bar s \to D_s^+$.明确显示了$ d_s^{\ pm} $和$ν_τ / {\overlineν}_τ$生产率的不同贡献。在$ν_τ / \overlineν_τ +^{208} \！\ mathrm {pb} $反应中，给出了许多观察到的$ν_τ / \overlineν_τ$的估计值，给出了200万个目标。
We discuss cross sections for $ν_τ$ and ${\overline ν}_τ$ production from the direct $D_s^{\pm} \to ν_τ/{\overline ν}_τ$ and chain $D_s^{\pm} \to τ^+/τ^- \to ν_τ/{\overline ν}_τ$ decays in $p\!+^{96}\!\mathrm{Mo}$ scattering with proton beam $E_{\mathrm{lab}}$ = 400 GeV \textit{i.e.} at $\sqrt{s}_{NN}$ = 27.4 GeV. In our calculations we include $D_s^{\pm}$ from charm fragmentation $c \to D_s^{+}$ and $\bar c \to D_s^-$ as well as those from subleading fragmentation of strange quarks/antiquarks $s \to D_s^-$ and $\bar s \to D_s^+$. The different contributions to $D_s^{\pm}$ and $ν_τ / {\overline ν}_τ$ production rates are shown explicitly. Estimates of a number of observed $ν_τ / \overlineν_τ$ in the $ν_τ / \overlineν_τ +^{208}\!\mathrm{Pb}$ reaction, with 2m long target are given.
