Emergent Universe Scenario in the Modified Chaplygin gas : Towards an Exact Solution and Observational Constraints
D. Panigrahi, S. Chatterjee, B. C. Paul
The Modified Chaplygin Gas (MCG) model is revisited as a unified framework for describing cosmic evolution. Due to the nonlinear field equations, exact solutions in cosmic time are…
An Alternative Approach to the Exact Solution of FRW-Type Spacetime with a Generalized Chaplygin Gas
D Panigrahi
The generalized Chaplygin gas model, characterized by the equation of state , is investigated within the framework of a Robertson-Walker spacetime. The resulti…
Studies of the Inhomogeneous Cosmology in Higher Dimensional space-time with a Cosmological Constant
D. Panigrahi, S. Chatterjee
We have studied the inhomogeneous cosmology in Kaluza-Klein spacetime with a positive cosmological constant in a dust dominated era (). Depending on the integration constant…
Evolution of FRW universe in variable modified Chaplygin gas model
Samarjit Chakraborty, Sarbari Guha, D. Panigrahi
In this paper we study the evolution of the FRW universe filled with variable modified Chaplygin gas (VMCG). We begin with a thermodynamical treatment of VMCG described by the equa…
How light a higgsino or a wino dark matter can become in a compressed scenario of MSSM
Manimala Chakraborti, Utpal Chattopadhyay, Sujoy Poddar
Higgsinos and Wino have strong motivations for being Dark Matter (DM) candidates in supersymmetry, but their annihilation cross sections are quite large. For thermal generation and…
New Limits on Heavier Electroweakinos and their LHC Signatures
Amitava Datta, Nabanita Ganguly, Sujoy Poddar
We investigate the heavier electroweakino sectors in several versions of the MSSM, which has not been explored so far in the light of the LHC data, and obtain new bounds using the…
