论文摘要
$λ_b\rightArrowλ_c\ ell^ - \barν_\ ell $ process在文献中已作为新物理学的探针进行了讨论。该过程在标量，矢量和张量HADRONIC电流的新物理模型中获得了贡献。这些电流的形式可以从夸克模型或晶格QCD获得。在这项工作中，我们提出了一个C代码，以读取标量，矢量和张量晶格QCD形式。参考文献中使用了Mathematica代码。 \ cite {datta：2017aue}读取形式。我们的C代码比Mathematica代码快得多，在该代码中，与Mathematica代码相比，C代码的壁时钟时间比为每个数据点1：64.2。
The $Λ_b \rightarrow Λ_c \ell^- \barν_\ell$ process has been discussed in the literatures as a probe for new physics. This process receives contributions in new physics models from scalar, vector, and tensor hadronic currents. The form factors of these currents can be obtained from the quark model or the lattice QCD. In this work, we present a c-code to read the scalar, vector, and tensor lattice QCD form factors. A Mathematica code was used in Ref. \cite{Datta:2017aue} to read the form factors. Our c-code is much faster than the Mathematica code where the ratio of the wall clock time for the c-code compared to the Mathematica code is 1:64.2 per data point.
