Stringy scaling of n-point Regge string scattering amplitudes

open access: yesJournal of High Energy Physics, 2023
We discover a stringy scaling behavior for a class of n-point Regge string scattering amplitudes (RSSA). The number of independent kinematics variables is found to be reduced by dim M $$ \mathcal{M} $$ .

Stability analysis of classical string solutions and the dressing method

open access: yesJournal of High Energy Physics, 2019
The dressing method is a technique to construct new solutions in non-linear sigma models under the provision of a seed solution. This is analogous to the use of autoBäcklund transformations for systems of the sine-Gordon type.

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 ...

Pinching parameters for open (super) strings

open access: yesJournal of High Energy Physics, 2018
We present an approach to the parametrization of (super) Schottky space obtained by sewing together three-punctured discs with strips. Different cubic ribbon graphs classify distinct sets of pinching parameters; we show how they are mapped onto each ...

Canonical description of T-duality with NSNS background

open access: yesJournal of High Energy Physics, 2020
We study T-duality with non-zero components of NSNS two form field along directions we dualize with the help of canonical formalism. As a result of this procedure we determine generalized Buscher’s rules.

Narain CFTs and error-correcting codes on finite fields

open access: yesJournal of High Energy Physics, 2022
We construct Narain CFTs from self-dual codes on the finite field F p through even self-dual lattices for any prime p > 2. Using this correspondence, we can relate the spectral gap and the partition function of the CFT to the error correction capability ...

Two-point string amplitudes

open access: yesJournal of High Energy Physics, 2019
We show that the two-point tree level amplitude in string theory in flat space is given by the standard free particle expression.

Courant bracket as T-dual invariant extension of Lie bracket

open access: yesJournal of High Energy Physics, 2021
We consider the symmetries of a closed bosonic string, starting with the general coordinate transformations. Their generator takes vector components ξ μ as its parameter and its Poisson bracket algebra gives rise to the Lie bracket of its parameters.

On the covariant quantization of tensionless bosonic strings in AdS spacetime [PDF]

open access: yes, 2003
The covariant quantization of the tensionless free bosonic (open and closed) strings in AdS spaces is obtained. This is done by representing the AdS space as an hyperboloid in a flat auxiliary space and by studying the resulting string constrained ...

On the positivity of Coon amplitude in D = 4

open access: yesJournal of High Energy Physics, 2022
The Coon amplitude is the unique solution to duality constraints with logarithmic Regge trajectories. A striking feature of this solution is that it interpolates between the Veneziano amplitude and a scalar particle amplitude.
