Polarization fractions and helicity-dependent CP asymmetries in $B_{(s)} \to I ¨ I ¨ , I ¨ K^{}$ and $K^{} K^{*}$ decays

Jian Chai, Shan Cheng, Feng-Qing Hu +3

In this paper, we present a phenomenological analysis of $B_{(s)} \to I ¨ I ¨ , I ¨ K^{*}$ and $K^{*} K^{*}$ decays using state-of-the-art perturbative QCD (pQCD) calculations. Our st…

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…
