Distribution amplitudes and functions of ground-state scalar and pseudoscalar charmonia
X. -Y. Zeng, Y. -Y. Xiao, Z. -N. Xu +2
Charmonia are often supposed to provide simple hydrogen-like ``atomic'' systems that can be used to obtain insights into heavier-quark QCD. We use continuum Schwinger function meth…
A Continuum Schwinger Method to Study the Pion's Generalized Parton Distribution
J. M. Morgado-Chávez, J. Segovia, F. de Soto +5
Generalised Parton Distributions (GPDs) provide multidimensional insight into hadron structure and are particularly relevant for the pion, whose dynamics are intimately linked to c…
Orbital angular momentum in the pion and kaon: rest-frame and light-front
Y. -Y. Xiao, Z. -N. Xu, Z. -Q. Yao +2
Orbital angular momentum (OAM) is not a Poincaré invariant quantity; so, its value is observer dependent. Notwithstanding that, in quantum chromodynamics, a Poincaré-invariant theo…
Imaging the charge distributions of flavor-symmetric and -asymmetric mesons
Yin-Zhen Xu, Adnan Bashir, Khépani Raya +2
We investigate the internal structure of a comprehensive set of pseudoscalar and vector mesons, including both flavor-symmetric and flavor-asymmetric systems, by reconstructing the…
Pion, Kaon and nucleon gravitational form factors
Zhao-Qian Yao, Yin-Zhen Xu, Daniele Binosi +5
A unified set of predictions for pion, kaon and nucleon gravitational form factors is obtained using a symmetry-preserving truncation of each relevant quantum field equation. A cru…
A brief comment on the similarities of the IR solutions for the ghost propagator DSE in Landau and Coulomb gauges
J. Rodríguez-Quintero
This brief note is devoted to reconcile the conclusions from a recent analysis of the IR solutions for the ghost propagator Dyson-Schwinger equations in Coulomb gauge with previous…
