Recently, the observation of the X(5568) by the D0 Collaboration has attracted a lot of interest both theoretically and experimentally. In a previous study(arXiv:1309.4743[hep-ph]), based on a fit to the lattice QCD scattering lengths of $DK$ and its coupled channels, unitary chiral perturbation theory (UChPT) can dynamically generate the $D_{s0}(2317)$. Inspired by that work and the recent work ... More

The semileptonic weak decay process of the $\Lambda_c$ baryon to the neutron $\Lambda_c\rightarrow ne^+\nu_e$ is examined. The transition form factors are investigated with light-cone QCD sum rules. The differential decay rate is obtained in the dynamical area by fitting the sum rules-allowed results with the dipole formula. The decay width and the branching ratio are estimated to be $\Gamma(\Lamb ... More

Gaussian expansion method (GEM) is a powerful method with high precision for few-body problems. The baryon and dibaryon are investigated in the framework of constituent quark model by using GEM.
A previously known class of analytic, exact solutions of prefect relativistic hydrodynamics is utilized to fit the new results on the pseudorapidity distributions with an acceleration parameter $\lambda$. Those results include a broad centrality range for Cu+Cu, Au+Au, Pb+Pb at RHIC and LHC. Based on hydrodynamic description of the pseudo-rapidity distribution with acceleration effects taken into ...

We analytically solve the full next-to-leading logarithmic Balitsky-Kovchegov equation in the saturation regime, which includes corrections from quark and gluon loops, and large double transverse logarithms. The analytic result for the S-matrix in the saturation regime shows that the linear rapidity decrease with rapidity of the exponent in running coupling case is replaced by rapidity raised ... More

With the dielectric function obtained from AdS/CFT correspondence, we investigate the strong-coupling wake potentials induced by the fast-moving charged particles with velocities v=0.55c and v=0.99c, respectively, and compare them with those in the weak-coupling case. We find that for v= 0.99c, the remarkable oscillation akin to Cherenkov-like radiation and the Mach cone in the weak-couplin ... More

In the dynamical evolutions of heavy ion collisions, heavy quark dipoles such as $c\bar c$ (or $b\bar b$) are produced from parton hard scatterings, and need a formation time to evolve into a certain bound states. Different from proton-proton collisions, the hot medium (called QGP) will affect the internal evolutions of heavy quark dipole due to color screening and parton inelastic collisions. Thi ... More
