Black Hole entropy by the brick wall method in four and five dimensions with U(1) charges
Elcio Abdalla, L. Alejandro Correa-Borbonet
Using the brick wall method we compute the statistical entropy of a scalar field in a nontrivial background, in two different cases. These background are generated by four and five…
Absence of higher order corrections to the non-Abelian topological mass term
F. T. Brandt, Ashok Das, J. Frenkel
We study the Yang-Mills-Chern-Simons theory systematically in an effort to generalize the Coleman-Hill result to the non-Abelian case. We show that, while the Chern-Simons coeffici…
Absence of higher order corrections to the non-Abelian Chern-Simons coefficient
F. T. Brandt, Ashok Das, J. Frenkel
We extend the Coleman-Hill analysis to non-Abelian Chern-Simons theories containing a tree level topological mass term. We show, in the case of a pure Yang-Mills-Chern-Simons theor…
Discrete symmetries as automorphisms of the proper Poincare group
I. L. Buchbinder, D. M. Gitman, A. L. Shelepin
We present the consistent approach to finding the discrete transformations in the representation spaces of the proper Poincaré group. To this end we use the possibility to establis…
Gravitational Interaction of Higher Spin Massive Fields and String Theory
I. L. Buchbinder, V. D. Pershin
We discuss the problem of consistent description of higher spin massive fields coupled to external gravity. As an example we consider massive field of spin 2 in arbitrary gravitati…
Two-loop corrections to the topological mass term in thermal QED_3
F. T. Brandt, Ashok Das, J. Frenkel +1
We study the radiative corrections to the Chern-Simons mass term at two loops in 2+1 dimensional quantum electrodynamics at finite temperature. We show that, in contrast to the beh…
