The Corrections to the Effective Neutral Current and to the Z Decay Rate in the Heavy Top Quark Limit
K. G. Chetyrkin, O. V. Tarasov
We find the effective neutral current in the heavy top quark limit up to and including the terms of order . The result is then employed to compute the correction of the same…
On the Heat Kernel in Covariant Background Gauge
E. I. Guendelman, A. Leonidov, V. Nechitailo +1
The first three coefficients in an expansion of the heat kernel of a nonminimal nonabelian kinetic operator taken in an arbitrary background gauge in arbitrary space-time dimension…
On the Interpretation of the Electroweak Precision Data
M. Bilenky, K. Kolodziej, M. Kuroda +1
The recent precision electroweak data on and are compared with the tree-level and the dominant-fermion-loop as well as the full one-loop standard-model…
Analytical calculation of critical temperatures in some spin systems
Z. Burda, J. Wosiek
A new method for locating analytically critical temperatures is discussed. It is exact for selfdual systems. When applied the two coupled layers of Ising spins it deviates from our…
The Potential of a New Linear Collider for the Measurement of the Trilinear Couplings among the Electroweak Vector Bosons
M. Bilenky, J. -L. Kneur, F. M. Renard +1
We study the accuracy to be obtained in measuring trilinear and couplings in the reaction at "New Linear Collider" energies of to…
The analysis of Polyakov loop and spin correlators in finite volumes
J. Engels, V. K. Mitrjushkin, T. Neuhaus
We derive an analytic expression for point to point correlation functions of the Polyakov loop based on the transfer matrix formalism. The contributions from the eigenvalues of the…
