Heterotic string field theory with manifest spacetime supersymmetry

Journal of High Energy Physics
Using the hybrid formalism with manifest N = 1 d = 4 spacetime supersymmetry, we construct the quadratic term in the heterotic superstring field theory action.

Worldsheet formalism for decoupling limits in string theory

Journal of High Energy Physics
We study the bosonic sector of a decoupling limit of type IIA superstring theory, where a background Ramond-Ramond one-form is fined tuned to its critical value, such that it cancels the associated background D0-brane tension.

Superstring limit of Yang–Mills theories [PDF]

Physics Letters B, 2016
It was pointed out by Shifman and Yung that the critical superstring on $X^{10}={\mathbb R}^4\times Y^6$, where $Y^6$ is the resolved conifold, appears as an effective theory for a U(2) Yang-Mills-Higgs system with four fundamental Higgs scalars defined on $ _2\times{\mathbb R}^2$, where $ _2$ is a two-dimensional Lorentzian manifold.

Carrollian Amplitudes from Strings

Journal of High Energy Physics
Carrollian holography is supposed to describe gravity in four-dimensional asymptotically flat space-time by the three-dimensional Carrollian CFT living at null infinity.

Strings on celestial sphere

Nuclear Physics B, 2018
We transform superstring scattering amplitudes into the correlation functions of primary conformal fields on two-dimensional celestial sphere. The points on celestial sphere are associated to the asymptotic directions of (light-like) momenta of external ...

On finite-size d-branes in superstring theory

Journal of High Energy Physics, 2019
We test exact marginality of the deformation describing the blow-up of a zero- size D(−1) brane bound to a background of D3-branes by analyzing the equations of motion of superstring field theory to third order in the size.

STATUS OF SUPERSTRING AND M-THEORY [PDF]

International Journal of Modern Physics A, 2010
The first lecture gives a colloquium-level overview of string theory and M-theory. The second lecture surveys various attempts to construct a viable model of particle physics. A recently proposed approach, based on F-theory, is emphasized.

Dual D-brane actions in nonrelativistic string theory

Journal of High Energy Physics, 2022
We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory.
