Spiked instantons from intersecting D-branes

Nuclear Physics B, 2017
The moduli space of spiked instantons that arises in the context of the BPS/CFT correspondence [22] is realised as the moduli space of classical vacua, i.e.

Open String Renormalization Group Flow as a Field Theory

Fortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract This article shows that the integral flow‐lines of the RG‐flow of open string theory can be interpreted as the solitons of a Hořova–Lifshitz sigma‐model of open membranes. The authors argue that the effective background description of this model implies the g‐theorem of open string theory.

Interacting Dark Matter and q‐Deformed Dark Energy Nonminimally Coupled to Gravity

Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
In this paper, we propose a new approach to study the dark sector of the universe by considering the dark energy as an emerging q‐deformed bosonic scalar field which is not only interacting with the dark matter, but also nonminimally coupled to gravity, in the framework of standard Einsteinian gravity.

Closed string tachyon condensation revisited

Journal of High Energy Physics
We consider condensation of nearly marginal matter tachyons in closed string field theory and observe that upon restricting to a subspace of states not containing the ghost dilaton, the on-shell value of the action is proportional to the shift of the ...

Finite temperature corrections to tachyon mass in intersecting D-branes

Journal of High Energy Physics, 2017
We continue with the analysis of finite temperature corrections to the Tachyon mass in intersecting branes which was initiated in [1]. In this paper we extend the computation to the case of intersecting D3 branes by considering a setup of two ...

Initial value problem in string-inspired nonlocal field theory

Journal of High Energy Physics, 2022
We consider a nonlocal scalar field theory inspired by the tachyon action in open string field theory. The Lorentz-covariant action is characterized by a parameter ξ 2 that quantifies the amount of nonlocality.

Carroll membranes

Journal of High Energy Physics, 2019
We explore Carroll limit corresponding to M2 as well as M3 branes propagating over 11D supergravity backgrounds in M theory. In the first part of the analysis, we introduce the membrane Carroll limit associated to M2 branes propagating over M theory ...

Tachyon Condensation and Black Hole Entropy [PDF]

Physical Review Letters, 2002
String propagation on a cone with deficit angle $2π(1-{1\over N})$ is considered for the purpose of computing the entropy of a large mass black hole. The entropy computed using the recent results on condensation of twisted-sector tachyons in this theory is found to be in precise agreement with the Bekenstein-Hawking entropy.

Quantum corrections for D-brane models with broken supersymmetry

Journal of High Energy Physics, 2019
Intersecting D-brane models and their T-dual magnetic compactifications yield attractive models of particle physics where magnetic flux plays a twofold role, being the source of fermion chirality as well as supersymmetry breaking.
