论文摘要
在本文中，我们提出了两种机器学习算法，以识别LHC在辐射$ W $ boson衰减中以颜色单线状态产生的$ D $介子。该组合的网络算法能够通过其耐药衰变识别$ d $ Mesons的效率为47％，同时抑制了100倍的夸克和Gluon喷气机的背景。使用开发的算法，我们对$ \ \ \ \ \ natercal {b}（w \ w \ to d _ d _ d _ d _ d_）进行了前瞻性研究。
In this paper we present two machine learning algorithms to identify $D$ mesons produced in a color singlet state from radiative $W$ boson decays at the LHC. The combined network algorithm is able to identify $D$ mesons via its hadronic decays with an efficiency of 47% while suppressing a background of quark and gluon jets by a factor of 100. Using the developed algorithm, we perform a prospective study for the measurement of $\mathcal{B}(W\to D_{s}γ)$.
