Superstring and Superstring Field Theory: A New Solution Using Ultradistributions of Exponential Type [PDF]

, 2022
In this paper we show that Ultradistributions of Exponential Type (UET) are appropriate for the description in a consistent way superstring and superstring field theories. A new Lagrangian for the closed superstring is given. We show that the superstring

Swampland variations on a theme by KKLT

Journal of High Energy Physics, 2019
The KKLT scenario in a warped throat, if consistent, provides a concrete counterexample to both the AdS scale separation and the dS swampland conjectures.

A large class of new gravitational and axionic backgrounds for four-dimensional superstrings

, 1994
A large class of new 4-D superstring vacua with non-trivial/singular geometries, spacetime supersymmetry and other background fields (axion, dilaton) are found.

Fluxes, Hierarchies, and Metastable Vacua in Supersymmetric Field Theories [PDF]

, 2007
This thesis concerns topics both in low-energy effective field theories from type IIB superstring flux compactifications and in fourdimensional, rigidly supersymmetric gauge theories.

Greedy-reduction from Shortest Linear Superstring to Shortest Circular Superstring

, 2021
A superstring of a set of strings correspond to a string which contains all the other strings as substrings. The problem of finding the Shortest Linear Superstring is a well-know and wellstudied problem in stringology.

Flowing between string vacua for the critical non-Abelian vortex with a deformation of N=2 Liouville theory

Physical Review D
It has been shown that non-Abelian solitonic vortex string supported in four-dimensional (4D) N=2 supersymmetric QCD (SQCD) with the U(2) gauge group and Nf=4 quark flavors becomes a critical superstring.

T-duality invariant approaches to string theory [PDF]

, 2010
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.
