We present results on a study of the dynamics of the formation of nonhomogeneous phases of the chiral transition transition in QCD. The possibility of the formation of a spatially modulated chiral condensate in the final stages of a heavy-ion collision is investigated assuming a Ginzburg-Landau-Langevin time evolution, using a free energy functional motivated by the Nambu—Jona-Lasinio mo ...

The measurements of hadronic form factors using the data samples collected with the BESIII detector at BEPCII collider are presented. The cross section of $e^+e^-\to p\bar{p}$ at 12 energies from $2232.4$ to $3671.0$ MeV are measured, the electromagnetic form factor is deduced, and the ratio $|G_{E}/G_{M}|$ is extracted by fitting the polar angle distribution. The cross section of $e^+e^-\to\pi^+\ ... More

Measurements of the Drell-Yan production of $W$ and $Z/\gamma$ bosons at the LHC provide a benchmark of our understanding of perturbative QCD and probe the proton structure in a unique way. The ATLAS collaboration has performed new high precision measurements at center-of-mass energies of 7 TeV. The measurements are performed for $W^+$, $W^-$ and $Z/\gamma$ bosons integrated and as a function of t ... More

Meson photoproduction is an important tool in the study of baryon resonances. The spectrum of broad and overlapping nucleon excitations can be greatly clarified by use of polarization observables. The N* program at Jefferson Lab with the CEBAF Large Acceptance Spectrometer (CLAS) includes experimental studies with linearly- and circularly-polarized tagged-photon beams, longitudinally- and transver ...

I discuss the fragmentation region at very high energies. Due to the mismatch of the saturation momenta of the target and projectile, there is a parametric difference between the energy density and multiplicity density of produced particles dependence upon saturation momenta. This parametric difference allows one to discriminate between thermalized and non-thermalized systems by measuring ... More
