Novel method for determining the light quark mass ratio using decays
Adolfo Guevara, Feng-Kun Guo, Hao-Jie Jing
We propose a novel approach for extracting symmetry breaking effects from symmetry conserving three-body decays. The method is based on mapping the Dalitz plot to a unit disk, and…

Discontinuity calculus and applications to two-body coupled-channel scattering
Hao-Jie Jing, Xiong-Hui Cao, Feng-Kun Guo
We present a novel method, termed discontinuity calculus, for computing discontinuities of complex functions. This framework enables a systematic investigation of both analytic con…
