15. Pushing fluid dynamics beyond its limits

Radoslaw Ryblewski (Institute of Nuclear Physics PAN)

06/11/2016, 11:00

The one-dimensional non-boost-invariant evolution of the quark-gluon plasma is analyzed within various frameworks of dissipative fluid dynamics. Predictions of all studied models are similar in the midrapidity region which stays in agreement with recent comparison of their gradient expansions, see arXiv:1608.07558. On the other hand, they differ significantly in the forward/backward region...

5. Comparative studies of pion spectra in p+p and Pb+Pb collisions (part II)

Andrzej Rybicki (Polish Academy of Sciences (PL))

In the previous Workshop in this series I addressed the characteristic structures in the
ratio of negative pion spectra in Pb+Pb divided by p+p collisions, published by NA61/SHINE
collaboration. This included in particular the enhancement of $\pi^-$ production at low
transverse momenta and/or high rapidities.

In the present talk I will discuss this enhancement as an interesting example of...

17. Vertex Detector of NA61/SHINE experiment for open charm measurements at CERN SPS energies

Anastasia Merzlaya (Jagiellonian University (PL), Saint-Petersburg State University (RU))

The heavy-ion programme of the NA61/SHINE experiment at CERN SPS is expanding to allow precise measurements of exotic particles with short lifetime. The study of open charm mesons allows for investigation of the properties of the hot and dense matter produced in nuclear-nuclear collisions. Vertex Detector for open charm measurements at the SPS is being constructed by the NA61/SHINE...

10. Examination of the heavy ion collisions using EPOS model in frame of BES program

Maria Stefaniak (Warsaw University of Technology)

Collisions of heavy-ions are major method used to study properties of matter. Such studies are performed with comparison of experimental data and model simulations.

One of theoretical description is Parton-Based Gribov-Regge theory included in the phenomenological model like EPOS. It was originally created to explain the processes at the highest energies obtained with LHC complex. EPOS...

24. Proton femtoscopy in BES

Sebastian Siejka (Warsaw University of Technology)

06/11/2016, 12:25

Through experiments with heavy-ion collisions at high energy we can study the properties of nuclear matter under extreme conditions. The information on the sizes of the particle-emitting sources can be inferred via the method of femtoscopy.

The femtoscopy method uses Quantum Statistics effects and the Final State Interactions to determine the space-time properties of the source. The radii...
