Singlet Free Energies of a Static Quark-Antiquark Pair.

Description: We study the singlet part of the free energy of a static quark anti-quark (Q{bar Q}) pair at finite temperature. The model is three flavor QCD with degenerate quark masses using N{sub {tau}} = 4 and 6 lattices with Asqtad staggered fermion action. We look at thermodynamics of the system around phase transition and study its scaling with lattice spacing and quark masses.

The Littlest Higgs Model and One-Loop Electroweak Precision Constraints.

Description: We present in this talk the one-loop electroweak precision constraints in the Littlest Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. We find the one-loop contributions are comparable to the tree level corrections in some regions of parameter space. A low cutoff scale is allowed for a non-zero triplet VEV. Constraints on various other parameters in the model are also discussed. The role of triplet scalars in constructing a consistent renorm… more
