论文摘要
Baryon数在粒子物理的标准模型（SM）中是保守的。巴里昂违规（BNV）是解释宇宙反对不对称物质的标准之一。超越SM（BSM）场景激励BNV。从这种角度来看，寻找各种BNV衰变变得很重要。 \\在这项工作中，我们考虑了重型迷人的介子的BNV衰变，对反普罗顿和正电子。该衰减通过DIM-6 SM有效场理论（SMEFT）操作员进行，并涉及12个独立的形式。我们在光锥总规则（LCSR）的框架中对这些形式的估计进行了估计。由于质子状态的插值电流不是唯一的，因此我们考虑了质子插值电流的不同形式，并讨论了选择插值电流的效果。
Baryon number is conserved in the Standard Model (SM) of particle physics. Baryon Number Violation (BNV) is one of the criteria to explain the matter anti-matter asymmetry of the universe. Various beyond the SM (BSM) scenarios motivate BNV. In that view, it becomes important to look for various BNV decays. \\ In this work, we consider the BNV decay of heavy charmed meson to anti-proton and positron. This decay proceeds via the dim-6 SM effective field theory (SMEFT) operator and involves 12 independent form factors. We give estimates for these form factors in the framework of Light Cone Sum Rules (LCSR). As the interpolation current for the proton state is not unique, we have considered different forms of proton interpolation current and discuss the effect of the choice of the interpolation current.
