Low-energy scattering of the and system
Jiang Yan, Xiong-Hui Cao, Meng-Lin Du +1
We investigate the low-energy interactions between the charmonium state and the light pseudoscalar mesons ( and ) within the framework of dispersion relations. We demon…
Renormalization of chiral perturbation theory with spinless matter field in curved spacetime
Cheng-Cheng Li, Xiong-Hui Cao, Feng-Kun Guo
We generalize chiral perturbation theory with spinless matter fields in the fundamental representation of to curved spacetime in the presence of an external gravitati…
Dispersive analysis of the transition form factor with - mixing effects
Xiong-Hui Cao, Feng-Kun Guo, Christoph Hanhart +1
Motivated by the discrepancies noted recently between the theoretical predictions of the electromagnetic transition form factor and the BESIII data, we reanalyze t…
Revisiting Roy-Steiner-equation analysis of pion-kaon scattering from lattice QCD data
Xiong-Hui Cao, Feng-Kun Guo, Zhi-Hui Guo +1
A comprehensive analysis of and amplitudes at large unphysical pion mass for all important partial waves is presented. A set of crossing-…
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…
Gravitational form factors of pions, kaons and nucleons from dispersion relations
Xiong-Hui Cao, Feng-Kun Guo, Qu-Zhi Li +2
The gravitational form factors of pions, kaons and the nucleons are investigated by employing modern dispersive techniques and chiral perturbation theory. We determine the gravitat…
