Speed of sound and baryon cumulants in heavy-ion collisions

no code implementations12 Mar 2021 Agnieszka Sorensen, Dmytro Oliinychenko, Volker Koch, Larry McLerran

We present a method that may allow an estimate of the value of the speed of sound as well as its logarithmic derivative with respect to the baryon number density in matter created in heavy-ion collisions.

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.

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.

Effects of local event-by-event conservation laws in ultra-relativistic heavy ion collisions at the particlization

1 code implementation22 Jan 2020 Dmytro Oliinychenko, Shuzhe Shi, Volker Koch

Many simulations of relativistic heavy ion collisions involve the switching from relativistic hydrodynamics to kinetic particle transport.

Particlization with local event-by-event conservation laws

1 code implementation26 Feb 2019 Dmytro Oliinychenko, Volker Koch

We present a sampling method for the transition from relativistic hydrodynamics to particle transport, commonly referred to as particlization, which preserves the local event-by-event conservation of energy, momentum, baryon number, strangeness, and electric charge.
