Tomography of light hadron structures: From LCDAs to iTMDs
Shan Cheng, Jian Chai, Ji-Xin Yu
To account for the soft transverse dynamics overlooked by the factorization formalism of exclusive QCD processes, we propose introducing the intrinsic transversal momentum di…
Polarization fractions and helicity-dependent CP asymmetries in and decays
Jian Chai, Shan Cheng, Feng-Qing Hu +3
In this paper, we present a phenomenological analysis of and decays using state-of-the-art perturbative QCD (pQCD) calculations. Our study…
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…
