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…
Heavy-to-light scalar form factors from Muskhelishvili-Omnès dispersion relations
De-Liang Yao, P. Fernandez-Soler, M. Albaladejo +2
By solving the Muskhelishvili-Omnès integral equations, the scalar form factors of the semileptonic heavy meson decays , , $\b…
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…
