Note about T-duality of non-relativistic string

open access: yesJournal of High Energy Physics, 2019
In this note we perform canonical analysis of T-duality for non-relativistic string in stringy Newton-Cartan background. We confirm recent result that T-duality along longitudinal spatial direction of stringy Newton-Cartan geometry maps non-relativistic ...

Plahte diagrams for string scattering amplitudes

open access: yesJournal of High Energy Physics, 2021
Plahte identities are monodromy relations between open string scattering amplitudes at tree level derived from the Koba-Nielsen formula. We represent these identities by polygons in the complex plane.

On N=1 Superconformal Algebra in the Non-Critical Bosonic String Theory

open access: yes, 1994
In a recent work it has been shown that the bosonic strings could be embedded into a special class of $N=1$ fermionic strings. We argue that the superpartners of any physical state in the spectrum of this fermionic string is non-physical. So, there is no

Non-relativistic D-brane from T-duality along null direction

open access: yesJournal of High Energy Physics, 2019
We construct new type of non-relativistic D-branes which are defined with the help of T-duality along null direction. We find Lagrangian and Hamiltonian formulation of these D-branes and study their properties under T-duality transformations.

An excursion into the string spectrum

open access: yesJournal of High Energy Physics, 2023
We propose a covariant technique to excavate physical bosonic string states by entire trajectories rather than individually. The approach is based on Howe duality: the string’s spacetime Lorentz algebra commutes with a certain inductive limit of sp ...

Zero Modes on Linked Strings

open access: yes, 1994
We study linked loops of string in the presence of bosonic condensates and fermionic zero modes on the strings. We find that the strings necessarily carry a current if the bosons have an Aharanov-Bohm interaction with the string.

Tachyon Condensation and Spectrum of Strings on D-branes [PDF]

open access: yes, 2001
We investigate spectrum of open strings on D-branes after tachyon condensation in bosonic string theory. We calculate 1-loop partition function of the string and show that its limiting forms coincide with partition functions of open strings with ...

A vertex operator algebra construction of the colour-kinematics dual numerator

open access: yesJournal of High Energy Physics, 2018
We derive a vertex operator based expression for the kinematic numerators of Yang-Mills amplitudes by applying the momentum kernel formalism to open string amplitudes. The expression involves an α ′ -weighted commutator induced by the monodromy relations

NEW GAUGE BOSONS FROM STRING MODELS [PDF]

open access: yesModern Physics Letters A, 1996
We address the mass ranges of new neutral gauge bosons and constraints on the accompanying exotic particles as predicted by a class of superstring models. Under certain assumptions about the supersymmetry breaking parameters we show that breaking of an additional U(1)′ symmetry is radiative when the appropriate Yukawa couplings of exotic particles are

New Form of the T-Duality Due to the Stability of a Compact Dimension

open access: yes, 2008
We study behaviors of a compact dimension and the $T$-duality, in the presence of the wrapped closed bosonic strings. When the closed strings interact and form another system of strings, the radius of compactification increases.
