Calculating the running coupling in strong electroweak models (2009)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
One possibility for Beyond Standard Model physics is a new strongly-interacting gauge theory. One way to determine if a non-abelian gauge theory is QCD-like or conformal is to measure the running of...
Chiral symmetry breaking in nearly conformal gauge theories (2009)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
We present new results on chiral symmetry breaking in nearly conformal gauge theories with fermions in the fundamental representation of the SU(3) color gauge group. The number of fermion flavors is...

Chiral properties of SU(3) sextet fermions (2009)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
SU(3) gauge theory with overlap fermions in the 2-index symmetric (sextet) and fundamental representations is considered. A priori it is not known what the pattern of chiral symmetry breaking is in a...
Nearly conformal gauge theories in finite volume (2009)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
We report new results on nearly conformal gauge theories with fermions in the fundamental representation of the SU(3) color gauge group as the number of fermion flavors is varied in the Nf = 4-16...
Topology and higher dimensional representations (2009)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
SU(3) gauge theory in the 2-index symmetric (sextet) and fundamental representations is considered in symmetric and periodic boxes. Using the overlap formulation in the quenched approximation it is...
Nearly conformal electroweak sector with chiral fermions (2008)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
SU(3) gauge theory with dynamical overlap fermions in the 2-index symmetric (sextet) representation is considered. This model may be a viable model of the electroweak symmetry breaking sector along...
Probing technicolor theories with staggered fermions (2008)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
One exciting possibility of new physics beyond the Standard Model is that the fundamental Higgs sector is replaced by a strongly-interacting gauge theory, known as technicolor. A viable theory must...
QCD finite T transition -- Comparison between Wilson and staggered results (2007)
Aoki, Yasumichi, Fodor, Zoltan, Katz, Sandor D., Szabo, Kalman K., Toth, Balint C.
A quantitative comparison between the finite temperature behaviour of the staggered and Wilson fermion formulations are performed. The comparison is based on a physical quantity that is expected to...
New Higgs physics from the lattice (2007)
Fodor, Zoltan, Holland, Kieran, Kuti, Julius, Nogradi, Daniel, Schroeder, Chris
We report the first results from our comprehensive lattice tool set to explore non-perturbative aspects of Higgs physics in the Standard Model. We demonstrate in Higgs-Yukawa models that Higgs mass...
Laszlo, Andras, Fodor, Zoltan, Vesztergombi, Gyorgy
Transverse momentum spectra of pi^{+/-} at midrapidity are measured at high p_T in p+p and p+Pb collisions at 158 GeV/nucleon beam energy by the NA49 experiment. This study is complementary to our...
The density of states method at non-zero chemical potential (2007)
Fodor, Zoltan, Katz, Sandor D., Schmidt, Christian
We study the QCD phase diagram by first principle lattice calculations at so far unreached high densities. For this purpose we employ the density of states method. Unimproved staggered fermions,...
Precision study of the SU(3) topological susceptibility in the continuum (2006)
Durr, Stephan, Fodor, Zoltan, Hoelbling, Christian, Kurth, Thorsten
We determine the topological susceptibility in the SU(3) pure gauge theory. We perform a series of high-statistics lattice studies and take the combined continuum and infinite volume limit. We find...
Lattice QCD as a video game (2006)
Egri, Gyozo I., Fodor, Zoltan, Hoelbling, Christian, Katz, Sandor D., Nogradi, Daniel, Szabo, Kalman K.
The speed, bandwidth and cost characteristics of today's PC graphics cards make them an attractive target as general purpose computational platforms. High performance can be achieved also for lattice...
The QCD phase diagram at finite density (2005)
Schmidt, Christian, Fodor, Zoltan, Katz, Sandor
We study the density of states method to explore the phase diagram of the chiral transition on the tempeature and quark chemical potential plane. Four quark flavours are used in the analysis. Though...
Closing the light gluino window (1997)
The running of the strong coupling constant, $R_{e^+e^-},R_Z$ and $R_\tau$ is studied on the three-loop level. Based on experimental data of $R_{e^+e^-},R_Z$ and $R_\tau$ and the LEP multijet...

We study the finite-temperature electroweak phase transition by numerical simulations of the four-dimensional SU(2)-Higgs model on anisotropic lattices with temporal extension $L_t=2$. The physically...
