Grand canonical potential for a static quark--anti-quark pair at finite T/mu
Z. Fodor, S. D. Katz, K. K. Szabo +1
We present numerical results on the static quark--anti-quark grand canonical potential in full QCD at non-vanishing temperature () and quark chemical potential (). Non-zero $…
Upper Bounds on the Neutrino-Nucleon Inelastic Cross Section
L. A. Anchordoqui, Z. Fodor, S. D. Katz +2
Extraterrestrial neutrinos can initiate deeply developing air showers, and those that traverse the atmosphere unscathed may produce cascades in the ice or water. Up to now, no such…
Dynamical overlap fermions, results with HMC algorithm
Z. Fodor, S. D. Katz, K. K. Szabo
We present results of a hybrid Monte-Carlo algorithm for dynamical, , four-dimensional QCD with overlap fermions. The fermionic force requires careful treatment, when changi…
Strong Neutrino-Nucleon Interactions at Ultrahigh Energies as a Solution to the GZK Puzzle
Z. Fodor, S. D. Katz, A. Ringwald +1
After a short review of the ultrahigh energy cosmic ray puzzle - the apparent observation of cosmic rays originating from cosmological distances with energies above the expected Gr…
Critical point of QCD at finite T and μ, lattice results for physical quark masses
Z. Fodor, S. D. Katz
A critical point (E) is expected in QCD on the temperature (T) versus baryonic chemical potential (μ) plane. Using a recently proposed lattice method for μ\neq 0 we study dynamical…
Finite T/μlattice QCD and the critical point
Z. Fodor, S. D. Katz
We present results on lattice QCD at finite temperature (T) and chemical potential (μ). We apply the overlap-improving multi-parameter reweighting technique for n_f=4 and 2+1 stagg…
