Calculation of the renormalized charmed-quark mass in Lattice QCD
A. Bochkarev, Ph. de Forcrand
The correlator of heavy-quark currents is calculated in quenched Lattice QCD on a -lattice for . The renormalized charmed quark mass is extracted fro…
Dispersive theory of charmonium on the Lattice
Alexander Bochkarev
Physical contribution of the high-energy part of hadronic spectrum is incorporated to describe the short-distance part of the correlator of heavy-quark currents obtained by quenche…
Electroweak Parameters in the -Scheme
A. I. Bochkarev, R. S. Willey
We study electroweak parameters sensitive to the radiative corrections, such as -ratio and $\hff$ decay rates in the $\ms$-scheme in the heavy -quark mass limit $m_{t} \gg m_…
Chiral symmetry at finite temperature: linear vs nonlinear -models
Alexander Bochkarev, Joseph Kapusta
The linear O() sigma model undergoes a symmetry restoring phase transition at finite temperature. We show that the nonlinear O() sigma model also undergoes a symmetry restori…
Determination of the renormalized heavy-quark mass in Lattice QCD
A. Bochkarev, Ph. de Forcrand
We study on the lattice the correlator of heavy-quark currents in the vicinity of vanishing momentum. The renormalized charmed quark mass, the renormalized strong coupling constant…
Nonperturbative Evaluation of the Sphaleron Transition Rate
A. Bochkarev
We review nonperturbative calculations of the rate of sphaleron transitions on the lattice in -dimensional field theories and introduce a way to perform the gauge-invariant Gi…
On the reliable measurement of the gluon condensate in lattice QCD
Alexander Bochkarev
We propose to calculate the gluon condensate in lattice QCD in an indirect way by extracting it from the correlator of hadronic currents of heavy quarks. Moments (derivatives with…
On the scheme dependence of the Electroweak radiative corrections
A. I. Bochkarev, R. S. Willey
We study the scheme dependence of the two-loop expression for the -parameter of the Standard Model in the heavy -quark mass limit . In the $\ms$-scheme the t…
Mesons in the quenched approximation at low temperature
A. I. Bochkarev, J. I. Kapusta
We use an effective low energy field theory to describe the coupling between glueballs and mesons as an analog of the quenched approximation in lattice QCD. This allows us to study…
On the relation between Euclidean and real time calculations of Green functions at finite temperature
A. Bochkarev
We find a relation between the semiclassical approximation of the temperature (Matsubara) 2-point correlator and the corresponding classical Green function in real time at finite t…
Nonperturbative evaluation of the diffusion rate in field theory at high temperatures
Alexander Bochkarev, Philippe de Forcrand
Kramer's approach to the rate of the thermally activated escape from a metastable state is extended to field theory. Diffusion rate in the 1+1-dimensional Sine-Gordon model as a fu…
