How much has DESI dark energy evolved since DR1?
Eoin Ó Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari +1
DESI has reported a dynamical dark energy (DE) signal based on the CDM model that is in conflict with Hubble tension. Recalling that the combination of DESI DR1 BAO and DR…
Is the Observable Universe Consistent with the Cosmological Principle?
Pavan Kumar Aluri, Paolo Cea, Pravabati Chingangbam +20
The Cosmological Principle (CP) -- the notion that the Universe is spatially isotropic and homogeneous on large scales -- underlies a century of progress in cosmology. It is conven…
1/N Resolution to Inflationary eta-Problem
A. Ashoorioon, U. Danielsson, M. M. Sheikh-Jabbari
We observe that the dominant one loop contribution to the graviton propagator in the theory of N (N>>1) light scalar fields ϕ_a (with masses smaller than M_{pl}/\sqrt{N}) minimally…
Nearing 11d Extremal Intersecting Giants and New Decoupled Sectors in D = 3,6 SCFT's
R. Fareghbal, C. N. Gowdigere, A. E. Mosaffa +1
We extend the analysis of arXiv:0801.4457 [hep-th] to charged black hole solutions of four-dimensional gauged supergravity which carry three charges. There are two decoupl…
Noncommutative Super Yang-Mills Theories with 8 Supercharges and Brane Configurations
M. M. Sheikh-Jabbari
In this paper we consider D=4 NCSYM theories with 8 supercharges. We study these theories through a proper type IIA (and M-theory) brane configuration. We find the one loop beta fu…
Mixed Boundary Conditions and Brane-String Bound States
H. Arfaei, M. M. Sheikh-Jabbari
In this article we consider open strings with mixed boundary conditions (a combination of Neumann and Dirichlet conditions at each end). We discuss how their end points show a $D_p…
