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

Stability analysis of classical string solutions and the dressing method
Journal 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.

Canonical description of T-duality with NSNS background
Journal 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.

Stringy scaling of n-point Regge string scattering amplitudes
Journal 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 $$ \mathcal{M} $$ .

Bosonic structure of realistic SO(10) supersymmetric cosmic strings [PDF]
, 2015 We study the bosonic structure of F-term Nambu-Goto cosmic strings forming in a realistic SO(10) implementation, assuming standard hybrid inflation. We describe the supersymmetric grand unified theory, and its spontaneous symmetry breaking scheme in ...

Pinching parameters for open (super) strings
Journal 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 ...

Narain CFTs and error-correcting codes on finite fields
Journal 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 ...

Courant bracket as T-dual invariant extension of Lie bracket
Journal 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.

Bosonic string theory with dust [PDF]
Classical and Quantum Gravity, 2014 We study a modified bosonic string theory that has a pressureless ``dust'' field on the string worldsheet. The dust is a real scalar field with unit gradient which breaks conformal invariance. Hamiltonian analysis reveals a time reparametrization constraint linear in the dust field momentum and a spatial diffeomorphism constraint. This feature provides
