Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We obtain the off‐shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti‐BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three (2 + 1)‐dimensional (3D) Abelian two‐form gauge theory with a single pseudoscalar field. The latter field (having the negative kinetic term

Directly from H-flux to the family of three nonlocal R-flux theories
Journal of High Energy Physics, 2019 In this article we consider T-dualization of the 3D closed bosonic string in the weakly curved background — constant metric and Kalb-Ramond field with one nonzero component, B xy = Hz, where field strength H is infinitesimal.

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.

Journal of High Energy Physics, 2018 We revisit the problem of charged string pair creation in a constant external electric field. The string states are massive and creation of pairs from the vacuum is a tunnelling process, analogous to the Schwinger process where charged particle-anti ...

String Theory is a hot topic of physics and mathematics. For the former, it stands as a huge sandbox where the formulation of difficult problems can be simplified and their hard computations carried out. For the latter, it stands as a direct contribution upstream, going from physics to maths, rather than the usual other way around.

Finite momentum at string endpoints
, 2013 We argue that classical strings, both bosonic and supersymmetric, can have finite energy and momentum at their endpoints. We show that in a general curved background, string endpoints must propagate along null geodesics as long as their energy remains ...

Effective action of bosonic string theory at order α ′3
Journal of High Energy PhysicsIn this work, we derive the classical effective action of bosonic string theory at order α ′3 for the metric, Kalb-Ramond field, and dilaton by imposing a higher-derivative extension of the Buscher rules on the circular reduction of the minimal basis at ...

Multiloop soft theorem for gravitons and dilatons in the bosonic string
Journal of High Energy Physics, 2019 We construct, in the closed bosonic string, the multiloop amplitude involving N tachyons and one massless particle with 26 − D compactified directions, and we show that at least for D > 4, the soft behaviors of the graviton and dilaton satisfy the same ...

All-order splits and multi-soft limits for particle and string amplitudes
Journal of High Energy PhysicsThe most important aspects of scattering amplitudes have long been thought to be associated with their poles. But recently a very different sort of “split” factorizations for a wide range of particle and string tree amplitudes have been discovered away ...

Topics in String Theory and Quantum Gravity
, 1992 These are the lecture notes for the Les Houches Summer School on Quantum Gravity held in July 1992. The notes present some general critical assessment of other (non-string) approaches to quantum gravity, and a selected set of topics concerning what we ...
