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 $k_{T}$ factorization formalism of exclusive QCD processes, we propose introducing the intrinsic transversal momentum di…

The $C P$ violations and branching ratios for $B_{c}^{+} \to D_{(s)}^{+} π^{+} π^{-} (K^{+} K^{-})$ from interference of the vector mesons in Perturbative QCD

Kun Shuai Ye, Gang Lü, Na-Wang +2

Within the framework of the perturbative QCD approach utilizing $K_{T}$ factorization, we have investigated the CP violations and branching ratios in the decay processes of $B_{c}^{+…

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…
