Renormalization of heavy-light currents in moving NRQCD
Renormalization heavy-light currents
2011/1/6
Heavy-light decays such as $B \to \pi \ell \nu$, $B \to K^{*} \gamma$ and $B \to K^{(*)} \ell \ell$ can be used to constrain the parameters of the Standard Model and in indirect searches for new physi...

Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Perturbative renormalization factors O(a^2) corrections
2011/1/7
In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculations is that they ar...
Supersymmetry non-renormalization theorem from a computer and the AdS/CFT correspondence
Supersymmetry non-renormalization theorem computer the AdS/CFT correspondence
2011/1/7
We perform Monte Carlo calculation of correlation functions in 4d N=4 super Yang-Mills theory on R*S^3 in the planar limit. In order to circumvent the well-known problem of lattice SUSY, we adopt the ...
Non-equilibrium time evolution of bosons from the functional renormalization group
Non-equilibrium time evolution of bosons functional renormalization group
2010/11/25
We develop a functional renormalization group approach to obtain the time evolution of the
momentum distribution function of interacting bosons out of equilibrium. Using an external outscattering rat...
Non-perturbative renormalization of quark mass in Nf=2+1 QCD with the Schroedinger functional scheme
Non-perturbative renormalization quark mass in Nf=2+1 QCD
2011/1/6
We present an evaluation of the quark mass renormalization factor for Nf=2+1 QCD. The Schroedinger functional scheme is employed as the intermediate scheme to carry out non-perturbative running from t...
A note on nonperturbative renormalization of effective field theory
note nonperturbative renormalization effective field theory
2010/4/13
Within the realm of contact potentials, the key structures intrinsic of nonperturbative renormalization of $T$-matrices are unraveled using rigorous solutions and an inverse form of algebraic Lippmann...
