Efficiency corrections for factorial moments and cumulants of overlapping sets of particles

1 code implementation6 Jan 2021 Volodymyr Vovchenko, Volker Koch

In this note we discuss subtleties associated with the efficiency corrections for measurements of off-diagonal cumulants and factorial moments for a situation when one deals with overlapping sets of particles, such as correlations between numbers of protons and positively charged particles.

Pion condensation in the early Universe at nonvanishing lepton flavor asymmetry and its gravitational wave signatures

no code implementations4 Sep 2020 Volodymyr Vovchenko, Bastian B. Brandt, Francesca Cuteri, Gergely Endrődi, Fazlollah Hajkarim, Jürgen Schaffner-Bielich

We investigate the possible formation of a Bose-Einstein condensed phase of pions in the early Universe at nonvanishing values of lepton flavor asymmetries.

Cumulants of multiple conserved charges and global conservation laws

1 code implementation8 Jul 2020 Volodymyr Vovchenko, Roman V. Poberezhnyuk, Volker Koch

We analyze the behavior of cumulants of conserved charges in a subvolume of a thermal system with exact global conservation laws by extending a recently developed subensemble acceptance method (SAM) [V. Vovchenko et al., arXiv:2003. 13905] to multiple conserved charges.

Connecting fluctuation measurements in heavy-ion collisions with the grand-canonical susceptibilities

1 code implementation31 Mar 2020 Volodymyr Vovchenko, Oleh Savchuk, Roman V. Poberezhnyuk, Mark I. Gorenstein, Volker Koch

We derive the relation between cumulants of a conserved charge measured in a subvolume of a thermal system and the corresponding grand-canonical susceptibilities, taking into account exact global conservation of that charge.

Canonical statistical model analysis of p-p, p-Pb, and Pb-Pb collisions at the LHC

1 code implementation7 Jun 2019 Volodymyr Vovchenko, Benjamin Dönigus, Horst Stoecker

Exact baryon number conservation is found to be even more important than that of strangeness in the canonical suppression picture at the LHC, in contrast to intermediate and low collision energies.

Thermal-FIST: A package for heavy-ion collisions and hadronic equation of state

5 code implementations16 Jan 2019 Volodymyr Vovchenko, Horst Stoecker

A distinct feature of this package is the presence of the graphical user interface frontend -- QtThermalFIST -- which is designed for fast and convenient general-purpose HRG model applications.

Multiplicity dependence of light nuclei production at LHC energies in the canonical statistical model

1 code implementation15 Aug 2018 Volodymyr Vovchenko, Benjamin Donigus, Horst Stoecker

The statistical model with exact conservation of baryon number, electric charge, and strangeness - the Canonical Statistical Model (CSM) - is used to analyze the dependence of yields of light nuclei at midrapidity on charged pion multiplicity at the LHC.

Finite resonance widths influence thermal model description of hadron yields

1 code implementation5 Jul 2018 Volodymyr Vovchenko, Mark I. Gorenstein, Horst Stoecker

Different scenarios for modeling resonances in a thermal model description of hadron yields measured in heavy-ion collisions are explored: the zero-width approximation, the energy independent Breit-Wigner scheme, and the energy dependent Breit-Wigner (eBW) scheme.
