B^0_s and B^0 Mixing in the Standard Model and Beyond: A Progress Report
B^0_s B^0 Mixing the Standard Model
2011/1/6
We give a progress report on the calculation of B meson mixing matrix elements, focusing on contributions that could arise beyond the Standard Model. The calculation uses asqtad (light quark) and Ferm...
Can the matter-antimatter asymmetry be easier to understand within the "spin-charge-family-theory", predicting twice four families and two times $SU(2)$ vector gauge and scalar fields?
the matter-antimatter asymmetry spin-charge-family-theory
2010/12/27
This contribution is an attempt to try to understand the matter-antimatter asymmetry in the universe within the {\it spin-charge-family-theory} if assuming that transitions in non equilibrium processe...
Technicolor and other theories of dynamical electroweak symmetry breaking invoke chiral symmetry breaking triggered by strong gauge-dynamics, analogous to that found in QCD, to explain the observed W,...

Semileptonic decays of K and D mesons in 2+1 flavor QCD
Semileptonic decays K and D mesons in 2+1 flavor QCD
2011/1/6
The experimentally measured rates of the semileptonic decays K -> pi l nu and D -> K(pi) l nu can be combined with lattice calculations of the associated form factors to precisely extract the CKM matr...

Operator algebra quantum groups of universal gauge groups
Operator algebra quantum groups universal gauge groups
2010/12/24
In this paper, we quantize universal gauge groups such as SU(\infty), in the sigma-C*-algebra setting. More precisely, we propose a concise definition of sigma-C*-quantum groups and explain the conce...
We discuss the status of different determinations of alpha_s, motivating a precise and reliable computation from lattice QCD. In order to suppress perturbative errors, the non-perturbative computation...

Properties of local Polyakov loops for SU(2) and SU(3) lattice gauge theory at finite temperature are analyzed. We show that spatial clusters can be identified where the local Polyakov loops have valu...

New soliton generating transformations in the bosonic sector of heterotic string effective theory
soliton generating transformations heterotic string effective theory
2010/12/23
In the author's paper (Phys.Rev. D80, 041901(R) (2009)), the integrable structure of the symmetry reduced bosonic dynamics in the low energy heterotic string effective theory was presented. In that p...
We present an update of our calculation of the form factor for B -> D* l nu at zero recoil, with higher statistics and finer lattices. As before, we use the Fermilab action for b and c quarks, the asq...

Large-N reduction of SU(N) Yang-Mills theory with massive adjoint overlap fermions
Large-N reduction SU(N) Yang-Mills theory
2011/1/6
We study four dimensional large-N SU(N) Yang-Mills theory coupled to adjoint overlap fermions on a single site lattice. Lattice simulations along with perturbation theory show that the bare quark mass...
