Sphere-level Ramond-Ramond couplings in Ramond-Neveu-Schwarz formalism
Hamid R. Bakhtiarizadeh, Mohammad R. Garousi
We calculate in details the sphere-level scattering amplitude of two Ramond-Ramond (RR) and two Neveu-Schwarz-Neveu-Schwarz (NSNS) vertex operators in type II superstring theories…
Casimir-like corrections to the classical tensions of the strings and membranes
Y. Koohsarian, A. Shirzad
We find the Casimir-like energies for strings and membranes. We show that the related Casimir forces can be interpreted as quantum corrections to the classical tensions of the stri…

In this paper we introduce a generalization of Hilbert C-modules which are pre- Finsler module namely C-semi-inner product spaces. Some properties and results of such spaces are in…
Exact cosmological solutions from Hojman conservation quantities
Salvatore Capozziello, Mahmood Roshan
We present a new approach to find exact solutions for cosmological models. By requiring the existence of a symmetry transformation vector for the equations of motion of the given c…
T-duality of D-brane action at order in bosonic string theory
Mohammad R. Garousi, Ahmad Ghodsi, Tooraj Houri +1
In bosonic string theory, it is known that the Buscher rules for the T-duality transformations receive quantum corrections at order . In this paper, we use the consistency of t…
Dual 2d CFT Identification of Extremal Black Rings from Holes
Ahmad Ghodsi, Hanif Golchin, M. M. Sheikh-Jabbari
Five dimensional Einstein gravity vacuum solutions in general fall into two classes of black rings with horizon topology S^2 \times S^1, and black holes with horizon topology S^3.…

M. Ghasemnezhad, M. Khajavi, S. Abbassi
We examine the effect of thermal conduction on the observational properties of a super critical hot magnetized flow. We obtained self-similar solution of a magnetized disc when the…
Asymmetric transition disks: Vorticity or eccentricity?
S. Ataiee, P. Pinilla, A. Zsom +3
Context. Transition disks typically appear in resolved millimeter observations as giant dust rings surrounding their young host stars. More accurate observations with ALMA have sho…
