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…

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

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

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