New Insights on Low Energy Scattering Amplitudes: Comprehensive Analyses at Level

Yu-Fei Wang, De-Liang Yao, Han-Qing Zheng

A production representation of partial-wave matrix is utilized to construct low-energy elastic pion-nucleon scattering amplitudes from cuts and poles on complex Riemann sheets.…

On the Existence of Resonance in Channel of Scatterings

Yu-Fei Wang, De-Liang Yao, Han-Qing Zheng

Low-energy partial-wave scattering data is reexamined with the help of the production representation of partial-wave matrix, where branch cuts and poles are thoroughly und…

Weak pion production off the nucleon in covariant chiral perturbation theory

De-Liang Yao, Luis Alvarez-Ruso, Astrid N. Hiller Blin +1

Weak pion production off the nucleon at low energies has been systematically investigated in manifestly relativistic baryon chiral perturbation theory with explicit inclusion of th…

Masses and sigma terms of doubly charmed baryons up to in manifestly Lorentz-invariant baryon chiral perturbation theory

De-Liang Yao

We calculate the masses and sigma terms of the doubly charmed baryons up to next-to-next-to-next-to-leading order (i.e., ) in a covariant baryon chiral perturbati…
