Black Hole Microstates and Attractor Without Supersymmetry
Atish Dabholkar, Ashoke Sen, Sandip Trivedi
Due to the attractor mechanism, the entropy of an extremal black hole does not vary continuously as we vary the asymptotic values of various moduli fields. Using this fact we argue…
Corrections to Tri-bimaximal Neutrino Mixing: Renormalization and Planck Scale Effects
Amol Dighe, Srubabati Goswami, Werner Rodejohann
We study corrections to tri-bimaximal (TBM) neutrino mixing from renormalization group (RG) running and from Planck scale effects. We show that while the RG effects are negligible…
Physics with a very long neutrino factory baseline
Raj Gandhi, Walter Winter
We discuss the neutrino oscillation physics of a very long neutrino factory baseline over a broad range of lengths (between 6000 km and 9000 km), centered on the ``magic baseline''…
A Critical Analysis of Goldberger-Wise Stabilization in Randall-Sundrum Scenario
Anindya Dey, Debaprasad Maity, Soumitra SenGupta
The Goldberger-Wise mechanism of stabilizing modulus in the Randall-Sundrum braneworld,by introducing a bulk scalar field with quartic interaction terms localized at the 3-branes h…
Spinning Strings as Small Black Rings
Atish Dabholkar, Norihiro Iizuka, Ashik Iqubal +2
Certain supersymmetric elementary string states with spin can be viewed as small black rings whose horizon has the topology of S^1 \times S^{d-3} in a d-dimensional string theory.…
Is Modified Chaplygin gas along with barotropic fluid responsible for acceleration of the Universe?
Writambhara Chakraborty, Ujjal Debnath
In this letter, we have considered a model of the universe filled with modified Chaplygin gas and another fluid (with barotropic equation of state) and its role in accelerating pha…
