Quark mass dependence of the vacuum electric conductivity induced by the magnetic field in SU(2) lattice gluodynamics
the vacuum electric conductivity induced the magnetic field in SU(2) lattice gluodynamics
2011/1/6
We study the electric conductivity of the vacuum of quenched SU(2) lattice gauge theory induced by the magnetic field B as a function of the bare quark mass m. The conductivity grows as the quark mass...

Low Mass Gluino within the Sparticle Landscape, Implications for Dark Matter, and Early Discovery Prospects at LHC-7
Low Mass Gluino Sparticle Landscape Dark Matter
2010/12/24
We analyze supergravity models that predict a low mass gluino within the landscape of sparticle mass hierarchies. The analysis includes a broad class of models that arise in minimal and in non-minimal...
We present the results of the recent high precision lattice calculation of the average up/down, strange and charm quark masses performed by ETMC with Nf=2 twisted mass Wilson fermions. The analysis in...

Higgs boson mass bounds in the presence of a very heavy fourth quark generation
Higgs boson mass bounds quark generation
2011/1/6
We study the effect of a potential fourth quark generation on the upper and lower Higgs boson mass bounds. This investigation is based on the numerical evaluation of a chirally invariant lattice Higgs...

2011/1/6
We report the status of nucleon structure calculations on the (2+1)-flavor dynamical domain-wall fermions ensembles with pion masses as low as 180 and 250 MeV on a lattice with about 4.6 fm spatial ex...

Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties of the decay consta...
Comparison of the mass preconditioned HMC and the DD-HMC algorithm for two-flavour QCD
the mass preconditioned HMC the DD-HMC algorithm
2011/1/6
Mass preconditioned HMC and DD-HMC are among the most popular algorithms to simulate Wilson fermions. We present a comparison of the performance of the two algorithms for realistic quark masses and la...

Leading order hadronic g-2 from twisted mass QCD
2011/1/7
We calculate the leading order hadronic contribution to the muon anomalous magnetic moment using twisted mass lattice QCD. The pion masses range from 330 MeV to 650 MeV. We use two lattice spacings, a...

2011/1/14
We study the quarkmass dependence of the QCD phase transition by an effective potential defined
through the distribution function of observables. As a test of the method, we study the first
