16. Two-photon processes $\gamma\gamma\rightarrow \pi^{+}\pi^{-}, K^{+}K^{-}$ in $k_{T}$ factorization

Cong WANG

As one of the simplest hadronic processes, $\gamma\gamma\rightarrow M^{+}M^{-}$ ($M=\pi,K$) could be a good testing ground for our understanding of the perturbative and nonperturbative structure of QCD, and will be studied with high precision at BELLE-II in the near future. In this paper, we revisit these processes with twist-3 corrections in the perturbative QCD approach based on the $k_{T}$...

17. Radiative decays of $h_{c}$ to the light mesons $\eta^{(\prime)}$: A perturbative QCD calculation

We study the radiative decays $h_{c}\rightarrow\gamma\eta^{(\prime)}$ in the framework of perturbative QCD and evaluate analytically the one-loop integrals with the light quark masses kept. Interestingly, the branching ratios $\mathcal{B}(h_{c}\rightarrow\gamma\eta^{(\prime)})$ are insensitive to both the light quark masses and the shapes of $\eta^{(\prime)}$ distribution amplitudes. And it is...

11. Interplaying mechanisms behind inclusive jet $R_{AA}$ and extraction of jet energy loss distributions

The observed suppression of inclusive jets in heavy-ion collisions at LHC has a very weak $p_{T}$ dependence over a large range of $p_{T}$ = 50-1000 GeV and is almost independent of the colliding energy, though the initial energy density of the formed QGP has increased significantly from $\sqrt{s}$ = 2.76 to 5.02 TeV. This interesting phenomenon is fully investigated in the linear Boltzmann...

1. The elliptic flow of open heavy flavor in pA collisions from initial state

Yu SHI

The azimuthal angular correlation between a heavy-flavor meson ($J/ \Psi$ and $D^0$) and a light hadron has been measured firstly by the CMS experiment. The elliptic flow of J/psi from the initial state has been successful described not long ago. We investigate the angular correlation between a open heavy flavor meson and a charged light hadron in the Color Glass Condensate framework. Our...
