24. Coupling of $\Lambda$ to the Atomic Nucleus

Jan Pokorný (CTU FNSPE)

We discuss the coupling of the $\Lambda$ particle to the atomic nucleus in the mean-field approximation. The mean field is constructed by the Hartree-Fock (HF) method. We develop a formalism of the HF method including the three-body NNN and $\Lambda$NN interactions. The HF basis is used as a starting point for the Tamm-Dancoff Approximation (TDA). We present a generalization of the TDA that...

6. Azimuthally sensitive femtoscopy with sorted events

Jakub Cimerman (České vysoké učení technické v Praze)

In the first part of the talk we shall investigate how the averaging
over a large number of events influences the shape of the observed
correlation function. We demonstrate that a shape characterised by Levy
distribution may result from an average over Gaussian sources with
varying sizes and orientations. We then propose to sort the events
according to their similarity and investigate...

Presentation

With the help of a master equation we study the evolution of the multiplicity distribution. Particularly we focus on the third and fourth factorial moments from which all other kinds of moments can be calculated.We first study how the third and the fourth moments thermalise when the kinetic temperature is fixed. Then we study the evolution of the moments in a situation with decreasing...

37. Multiplicity Fluctuations and Resonances in Heavy-Ion Collisions

Josef Uchytil (CTU FNSPE)

The number of particles produced in ultra-relativistic nucleus-nucleus collisions is well described by the statistical model. In this model, the particle yields depend on temperature and chemical potential. However, statistical physics can also predict multiplicity fluctuations, which can subsequently be compared to experimental data. Our primary aim research is to provide information on how...

34. Correlation femtoscopy

Lukáš Holub (CTU FNSPE)

18/01/2018, 11:30

In my presentation, I will present a preliminary analysis of correlation femtoscopy measurements of two positive and negative charged pions at small relative momenta, using STAR data from p−Au collisions at $\sqrt{sNN}$ = 200 GeV. The correlation includes Bose-Einstein and Coulomb interaction. The strong interaction is not included here because it is not relevant.
Obtained correlation...
