Supersymmetry Parameter Analysis: SPA Convention and Project
J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…
Orbital phase spectroscopy of X-ray pulsars to study the stellar wind of the companion
U. Mukherjee, B. Paul
High Mass X-ray Binary Pulsars (HMXBP), in which the companion star is a source of supersonic stellar wind, provide a laboratory to probe the velocity and density profile of such w…
GMRT Observations of Microquasar V4641 Sgr
C. H. Ishwara-Chandra, A. Pramesh Rao
We report the GMRT observations of V4641 Sgr during the May 2002 outburst at radio frequencies of 610 and 244 MHz. This is the lowest frequency radio detection of this source. The…
Precision Microstate Counting of Small Black Rings
Atish Dabholkar, Norihiro Iizuka, Ashik Iqubal +1
We examine certain two-charge supersymmetric states with spin in five-dimensional string theories which can be viewed as small black rings when the gravitational coupling is large.…

We study rooted self avoiding polygons and self avoiding walks on deterministic fractal lattices of finite ramification index. Different sites on such lattices are not equivalent,…
Studying the effects of minimal length in large extra dimensional models in the jet + missing energy channels at hadron colliders
Gautam Bhattacharyya, Kumar Rao, K. Sridhar
Theories of quantum gravity suggest the existence of a minimal length scale. We study the consequences of a particular implementation of the idea of a minimal length scale in the m…
