Effective gravitational mass of the Ayón-Beato and Garc\'ıa metric
A. K. Sinha, G. K. Pandey, A. K. Bhaskar +4
In this paper, we calculate the effective gravitational mass of Ayón-Beato and Garc\'ıa regular (non-singular) static spherically symmetric asymptotically Minkowskian metric that i…
Dynamics on AdS2 and Enlargement of SL(2,R) to c=1 `cut-off Virasoro Algebra'
Balram Rai
We consider the enhancement of SL(2,R) to Virasoro algebra in a system of N particles on AdS2. We restrict our discussion to the case of non-interacting particles, and argue that t…
New String Excitations in the Two-Higgs Standard Model
C. Bachas, B. Rai, T. N. Tomaras
We establish the existence of a static, classically stable string solution in a region of parameters of the generic two-Higgs Standard Model. In an appropriate limit of parameters,…
Gravity and Domain Wall Problem
Balram Rai, Goran Senjanovic
It is well known that the spontaneous breaking of discrete symmetries may lead to conflict with big-bang cosmology. This is due to formation of domain walls which give unacceptable…
