Charge dependent relation between the masses of different generations and Neutrino masses

- B. Sazdović
- Physics
- 29 January 2015

Despite the enormous achievements, the Standard model of Particle physics can not be consider as complete theory of fundamental interactions. Among other things, it can not describe the gravitational… Expand

W-Strings on Curved Backgrounds

- A. Miković, B. Sazdović
- Physics
- 26 January 1996

We discuss a canonical formalism method for constructing actions describing propagation of W-strings on curved backgrounds. The method is based on the construction of a representation of the… Expand

$$T$$T-duality in a weakly curved background

- L. Davidović, B. Sazdović
- Physics
- 9 May 2012

We consider the closed string propagating in a weakly curved background which consists of a constant metric and a Kalb–Ramond field with an infinitesimally small coordinate-dependent part. We propose… Expand

Weakly curved background T-duals

- L. Davidović, B. Sazdović, B. Nikolić
- Mathematics
- 21 July 2016

We discuss the generalized T-dualization procedure, its connection to the standard procedure, and the results of its application to the arbitrary set of coordinates of the closed string moving in the… Expand

Generalized canonical quantization of antisymmetric tensor gauge theory

- M. Blagojević, D. Popović, B. Sazdović
- Physics
- 10 November 1988

Abstract The gauge-fixing problem in the nonabelian antisymmetric tensor gauge theory is discussed by using the systematic hamiltonian BRST approach. The BRST symmetry of the quantum action is… Expand

Off-shell BRST quantization of reducible gauge theories

- M. Blagojević, B. Sazdović
- Physics
- 15 June 1989

Abstract The quantization of the bosonic first-stage reducible gauge theories with closed classical gauge algebra is studied within the BRST approach. After constructing the off-shell nilpotent BRST… Expand

On the structure of ultraviolet divergences in the vacuum region of quantum electrodynamics

- B. Dragović, B. Sazdović
- Physics
- 1 April 1981

Starting from a finite QED in the Johnson-Baker-Willey formulation (1964), structures of UV divergences of (0 mod S mod 0) in QED are analysed. To obtain the finite QED in the vacuum region several… Expand

General solution of the WZNW system and 2D induced gravity in curved space-time

- B. Sazdović
- Physics
- 21 September 1998

We find the general solution of the equations of motion for the Wess-Zumino-Novikov-Witten (WZNW) system in curved space-time for arbitrary external gauge fields. Using the connection between the… Expand

Canonical approach to 2D supersymmetric WZNW model coupled to supergravity

- O. Mǐsković, B. Sazdović
- Physics
- 19 November 2001

Starting from the known representation of the Kac-Moody algebra in terms of the coordinates and momenta, we extend it to the representation of the super Kac-Moody and super Virasoro algebras. Then we… Expand

The T-dual symmetries of a bosonic string

- L. Davidović, B. Sazdović
- Physics
- 8 June 2018

We investigate whether the symmetry transformations of a bosonic string are connected by T-duality. We start with a standard closed string theory. We continue with a modified open string theory,… Expand
