Abstract
We present a Mathematica package designed to automatize the expansion of transition amplitudes calculated in the mass eigenstates basis (i.e. expressed in terms of physical masses and mixing matrices) into series of “mass insertions”, defined as off-diagonal entries of mass matrices in Lagrangian before diagonalization and identification of the physical states. The algorithm implemented in this package is based on the general “Flavor Expansion Theorem” proven in Dedes et al. (2015). The suppl...

本报告提出一款Mathematica软件包，旨在实现基于质量本征态基（即以物理质量及混合矩阵为表达形式）计算出的跃迁幅度的自动化展开，将其转化为一系列所谓的‘质量插入’形式，该形式定义为拉格朗日量在对角化及物理态识别之前质量矩阵的非对角元素。本软件包中实现的算法基于Dedes等人在2015年提出的通用‘味展开定理’。此外，补充...
