The static stationary axially symmetric background («infinite cosmic string») of the D = 4 string theory provided with an axion charge is studied in the effective theory approach. The most general exact solution is constructed. It is found that the Kalb-Ramond axion charge, present in the string topology R 3 × S 1 , produces nontrivial gravitational field configurations which feature horizons. The corresponding «no-hair» theorems are proved, which stress the uniqueness of black strings. The…

Topological mass term in effective Brane-World scenario with torsion
In this work we investigate a braneworld scenario where a Kalb-Ramond field propagates, together with gravity, in a five dimensional AdS slice. The rank-2 Kalb-Ramond field is associated with

Abstract The purpose of this work is to show that there exists an additional invariance of the β-function equations of string theory on d + 1-dimensional targets with d toroidal isometries. It
