The results for SU(N) Yang-Mills theories with N=3, 4, 5, 6, and 8 colors show a very mild dependence on N, supporting the idea that the QCD plasma could be described by models based on the large-N limit.
Lattice study of the jet quenching parameter.
How one can evaluate the soft contribution to the collision kernel characterizing this real-time phenomenon is explained, analyzing certain gauge-invariant operators in a dimensionally reduced effective theory (electrostatic QCD), which can be studied nonperturbatively via simulations on a Euclidean lattice.
A different kind of string
A bstractIn U(1) lattice gauge theory in three spacetime dimensions, the problem of confinement can be studied analytically in a semi-classical approach, in terms of a gas of monopoles with…
The phase diagram of Yang-Mills theory with a compact extra dimension
We present a non-perturbative study of the phase diagram of SU(2) Yang-Mills theory in a five-dimensional spacetime with a compact extra dimension. The nonrenormalizable theory is regularized on an…
Numerical simulations of a non-commutative theory: The Scalar model on the fuzzy sphere
- M. Panero
- 29 August 2006
We address a detailed non-perturbative numerical study of the scalar theory on the fuzzy sphere. We use a novel algorithm which strongly reduces the correlation problems in the matrix update process,…
Numerical properties of staggered quarks with a taste-dependent mass term
A bstractThe numerical properties of staggered Dirac operators with a taste-dependent mass term proposed by Adams [1, 2] and by Hoelbling  are compared with those of ordinary staggered and Wilson…

Mesons in large-N QCD
A bstractWe present the results of a systematic, first-principles study of the spectrum and decay constants of mesons for different numbers of color charges N, via lattice computations. We restrict…
Numerical properties of staggered overlap fermions
We report the results of a numerical study of staggered overlap fermions, following the construction of Adams which reduces the number of tastes from 4 to 2 without fine-tuning. We study the…
Lattice QCD study of inclusive semileptonic decays of heavy mesons
Abstract We present an ab initio study of inclusive semileptonic decays of heavy mesons from lattice QCD. Our approach is based on a recently proposed method, that allows one to address the study of…
