Quark mass correction to the string potential [PDF]

open access: yesPhysical Review D, 1995
A consistent method for calculating the interquark potential generated by the relativistic string with massive ends is proposed. In this approach the interquark potential in the model of the Nambu--Goto string with point--like masses at its ends is ...

String-corrected black holes [PDF]

open access: yesJournal of High Energy Physics, 2005
We investigate the geometry of four dimensional black hole solutions in the presence of stringy higher curvature corrections to the low energy effective action. For certain supersymmetric two charge black holes these corrections drastically alter the causal structure of the solution, converting seemingly pathological null singularities into timelike ...

Instanton corrections and Emergent Strings [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We study limits of infinite distance in the moduli space of 4d $$ \mathcal{N} $$ N = 2 string compactifications, in which instanton effects dominate.

String unification and threshold corrections [PDF]

open access: yesPhysics Letters B, 1993
The interpretation of the apparent unification of gauge couplings within supersymmetric theories depends on uncertainties induced through heavy particle thresholds. While in standard grand unified theories these effects can be estimated easily, the corresponding calculations are quite complicated in string unified theories and do exist only in models ...

α′-corrected black holes in String Theory [PDF]

open access: yesJournal of High Energy Physics, 2018
Abstract We consider the well-known solution of the Heterotic Superstring effective action to zeroth order in α ′ that describes the intersection of a fundamental string with momentum and a solitonic 5-brane and which gives a 3-charge, static, extremal, supersymmetric black hole in 5 dimensions upon dimensional ...

Nonminimal string corrections and supergravity [PDF]

open access: yesPhysical Review D, 2006
We reconsider the well-known issue of string corrections to Supergravity theory. Our treatment is carried out to second order in the string slope parameter. We establish a procedure for solving the Bianchi identities in the non minimal case, and we solve a long standing problem in the perturbative expansion of D=10, N=1 string corrected Supergravity ...

Curvature Expansion for the Gluodynamics String including Perturbative Gluonic Contributions [PDF]

open access: yes, 1997
Perturbation theory in the nonperturbative QCD vacuum and the non-Abelian Stokes theorem, representing a Wilson loop in the SU(2) gluodynamics as an integral over all the orientations in colour space, are applied to a derivation of the correction to the ...

Infinity in string cosmology: A review through open problems [PDF]

open access: yes, 2016
We review recent developments in the field of string cosmology with particular emphasis on open problems having to do mainly with geometric asymptotics and singularities.
