Bridging a gap between continuum-QCD and ab initio predictions of hadron observables
Daniele Binosi, Lei Chang, Joannis Papavassiliou +1
Within contemporary hadron physics there are two common methods for determining the momentum-dependence of the interaction between quarks: the top-down approach, which works toward…
Pion Valence-quark Parton Distribution Function
Lei Chang, Anthony W. Thomas
Within the Dyson-Schwinger equation formulation of QCD, a rainbow ladder truncation is used to calculate the pion valence-quark distribution function(PDF). The gap equation is reno…
Basic features of the pion valence-quark distribution function
Lei Chang, Cédric Mezrag, Hervé Moutarde +3
The impulse-approximation expression used hitherto to define the pion's valence-quark distribution function is flawed because it omits contributions from the gluons which bind quar…
Flavour symmetry breaking in the kaon parton distribution amplitude
Chao Shi, Lei Chang, Craig D. Roberts +3
We compute the kaon's valence-quark (twist-two parton) distribution amplitude (PDA) by projecting its Poincare'-covariant Bethe-Salpeter wave-function onto the light-front. At a sc…
Parton distribution amplitudes of light vector mesons
Fei Gao, Lei Chang, Yu-Xin Liu +2
A rainbow-ladder truncation of QCD's Dyson-Schwinger equations is used to calculate rho- and phi-meson valence-quark (twist-two parton) distribution amplitudes (PDAs) via a light-f…
