Form factors of light pseudoscalar mesons from the perturbative QCD approach
Jian Chai, Shan Cheng
We study the electromagnetic and meson-photon transition form factors (TFF) of light pseudoscalar mesons from the perturbative QCD (pQCD) approach. To comprehensively account for b…

Shedding light on the intrinsic transversal momentum distributions of pion and kaon
Jian Chai, Shan Cheng
We propose to introduce the intrinsic transversal momentum distribution functions (iTMDs), in conjunction with the light-cone distribution amplitudes (LCDAs), to elucidate the prob…
