Ratios of cumulants of conserved net charge fluctuations are sensitive to the degrees of freedom that are carriers of the corresponding quantum numbers in different phases of strong interaction matter. Using lattice QCD with 2+1 dynamical flavors and

Conserved Charge Fluctuations from Lattice QCD and the Beam Energy Scan

We discuss the next-to-leading order Taylor expansion of ratios of cumulants of net-baryon number fluctuations. We focus on the relation between the skewness ratio, $S_B\sigma_B = \chi_3^B/\chi_1^B$, and the kurtosis ratio, $\kappa_B\sigma_B^2 =\chi_

QCD equation of state to O(μB6) from lattice QCD

Autor: Swagata Mukherjee, Y. Maezawa, M. Wagner, P. Hegde, Peter Petreczky, Olaf Kaczmarek, Heng-Tong Ding, Christian Schmidt, Alexei Bazavov, P. Steinbrecher, Hauke Sandmeyer, Edwin Laermann, W. Soeldner, Sapana Sharma, Frithjof Karsch, Hiroshi Ohno

Publikováno v: Physical Review D. 95

We calculated the QCD equation of state using Taylor expansions that include contributions from up to sixth order in the baryon strangeness and electric charge chemical potentials. Calculations have been performed with the Highly Improved Staggered Q

Curvature of the freeze-out line in heavy ion collisions

Publikováno v: Physical Review D. 93

We calculate the mean and variance of net-baryon number and net-electric charge distributions from Quantum Chromodynamics (QCD) using a next-to-leading order Taylor expansion in terms of temperature and chemical potentials. We compare these expansion

Equation of state in (2+1)-flavor QCD

Publikováno v: Physical Review D. 90

We present results for the equation of state in ($2+1$)-flavor QCD using the highly improved staggered quark action and lattices with temporal extent ${N}_{\ensuremath{\tau}}=6$, 8, 10, and 12. We show that these data can be reliably extrapolated to

Additional Strange Hadrons from QCD Thermodynamics and Strangeness Freeze-out in Heavy Ion Collisions

Autor: W. Soeldner, Mathias Wagner, Heng-Tong Ding, Alexei Bazavov, Edwin Laermann, Frithjof Karsch, Hiroshi Ohno, Olaf Kaczmarek, P. Hegde, Swagata Mukherjee, Yu Maezawa, Sayantan Sharma, Christian Schmidt, Peter Petreczky

We compare lattice QCD results for appropriate combinations of net strangeness fluctuations and their correlations with net baryon number fluctuations with predictions from two hadron resonance gas (HRG) models having different strange hadron content
