Ultra high energy cosmic rays: clustering, GUT scale and neutrino masses
Z. Fodor
The clustering of ultra high energy (above 5\cdot 10^{19} eV) cosmic rays (UHECR) suggests that they might be emitted by compact sources. We present a statistical analysis on the s…
Differential directed flow in Au+Au collisions
A. Andronic, FOPI Collaboration
We present experimental data on directed flow in semi-central Au+Au collisions at incident energies from 90 to 400 A MeV. For the first time for this energy domain, the data are pr…
Four-dimensional lattice results on the MSSM electroweak phase transition
F. Csikor, Z. Fodor, P. Hegedus +3
We present the results of our large scale 4-dimensional (4d) lattice simulations for the MSSM electroweak phase transition (EWPT). We carried out infinite volume and continuum limi…
Lattice determination of the critical point of QCD at finite T and μ
Z. Fodor, S. D. Katz
Based on universal arguments it is believed that there is a critical point (E) in QCD on the temperature (T) versus chemical potential (μ) plane, which is of extreme importance for…
Determination of absolute neutrino masses from Z-bursts
Z. Fodor, S. D. Katz, A. Ringwald
Ultrahigh energy neutrinos (UHEν) scatter on relic neutrinos (Rν) producing Z bosons, which can decay hadronically producing protons (Z-burst). We compare the predicted proton spec…
A new method to study lattice QCD at finite temperature and chemical potential
Z. Fodor, S. D. Katz
Due to the sign problem, it is exponentially difficult to study QCD on the lattice at finite chemical potential. We propose a method --an overlap improving multi-parameter reweight…
Direct comparison of phase-space distributions of K- and K+ mesons in heavy-ion collisions at SIS energies - evidence for in-medium modifications of kaons ?
K. Wisniewski, P. Crochet, N. Herrmann
The ratio of K- to K+ meson yields has been measured in the systems RuRu at 1.69 A GeV, Ru+Zr at 1.69 A GeV, and Ni+Ni at 1.93 A GeV incident beam kinetic energy. The yield ratio i…
