Fluctuations of conserved charges at finite temperature from lattice QCD
Szabolcs Borsanyi, Zoltan Fodor, Sandor D. Katz +3
We present the full results of the Wuppertal-Budapest lattice QCD collaboration on flavor diagonal and non-diagonal quark number susceptibilities with 2+1 staggered quark flavors,…
Systematics of azimuthal asymmetries in heavy ion collisions in the 1 A GeV regime
FOPI Collaboration, W. Reisdorf, Y. Leifels +51
Using the large acceptance apparatus FOPI, we study central and semi-central collisions in the reactions (energies in A GeV are given in parentheses): 40Ca+40Ca (0.4, 0.6, 0.8, 1.0…
Measurement of Production Properties of Positively Charged Kaons in Proton-Carbon Interactions at 31 GeV/c
SHINE Collaboration, N. Abgrall, A. Aduszkiewicz +135
Spectra of positively charged kaons in p+C interactions at 31 GeV/c were measured with the NA61/SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data co…
The finite temperature QCD transition in external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +5
The effect of an external magnetic field on the finite temperature transition of QCD is studied. We measure thermodynamic observables including the quark condensates and susceptibi…
SU(2) chiral perturbation theory low-energy constants from staggered 2+1 flavor simulations
Enno E. Scholz, Szabolcs Borsanyi, Stephan Durr +5
We measure the pion mass and decay constant on ensembles generated by the Wuppertal-Budapest Collaboration, and extract the NLO low-energy constants l_3 and l_4 of SU(2) chiral per…
QCD thermodynamics with Wilson fermions
Szabolcs Borsanyi, Zoltan Fodor, Christian Hoelbling +6
QCD is investigated at finite temperature using Wilson fermions in the fixed scale approach. A 2+1 flavor stout and clover improved action is used at four lattice spacings allowing…
Antideuteron and deuteron production in mid-central Pb+Pb collisions at 158 GeV
Tome Anticic, NA49 collaboration
Production of deuterons and antideuterons was studied by the NA49 experiment in the 23.5% most central Pb+Pb collisions at the top SPS energy of =17.3 GeV. Invariant…
The QCD phase diagram for external magnetic fields
G. S. Bali, F. Bruckmann, G. Endrodi +5
The effect of an external (electro)magnetic field on the finite temperature transition of QCD is studied. We generate configurations at various values of the quantized magnetic flu…

The QCD transition is studied on lattices up to . The chiral condensate is presented as a function of the temperature, and the corresponding transition temperature is extra…
Correlations and fluctuations from lattice QCD
Szabolcs Borsanyi, Zoltan Fodor, Sandor D. Katz +3
We present the new results of the Wuppertal-Budapest lattice QCD collaboration on flavor diagonal and non-diagonal quark number susceptibilities with 2+1 staggered quark flavors, i…
Sigma term and strangeness content of octet baryons
S. Durr, Z. Fodor, T. Hemmert +11
By using lattice QCD computations we determine the sigma terms and strangeness content of all octet baryons by means of an application of the Hellmann-Feynman theorem. In addition…

G. Bali, S. Collins, S. Durr +18
We study the spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states. We use two sets of gauge configurations, one set fro…
Precision computation of the kaon bag parameter
S. Durr, Z. Fodor, C. Hoelbling +8
Indirect CP violation in K \rightarrow ππ decays plays a central role in constraining the flavor structure of the Standard Model (SM) and in the search for new physics. For many ye…
