Quantizing the rotating string with massive endpoints
We compute leading order quantum corrections to the Regge trajectory of a rotating string with massive endpoints using semiclassical methods. We expand the bosonic string action around a classical rotating solution to quadratic order in the fluctuations ...

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

Degeneracy Between the Regge Slope of Mesons and Baryons from Supersymmetry [PDF]
We consider the degeneracy between the Regge slope of mesons and baryons in QCD. We argue that within the "orientifold large-N approximation" asymptotically massive mesons and baryons become supersymmetric partners and hence degenerate.

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

The Nambu–Goto theory of closed bosonic strings moving in 1 + 3–dimensional Minkowski space: the quantum algebra of observables [PDF]
A relevant part of the quantum algebra of observables for the closed bosonic strings moving in 1 + 3–dimensional Minkowski space is presented in the form of generating relations involving still one, as yet undetermined, real free parameter.

Closed string deformations in open string field theory. Part I. Bosonic string [PDF]
Abstract This is the first of a series of three papers on open string field theories based on Witten star product deformed with a gauge invariant open/closed coupling. This de- formation is a tree-level tadpole which destabilizes the initial perturbative vacuum.

Stability analysis of classical string solutions and the dressing method
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.

On the positivity of Coon amplitude in D = 4
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.

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

The generalized Bergshoeff-de Roo identification. Part II
We recently introduced a T-duality covariant mechanism to compute all-order higher-derivative interactions in the heterotic string. Here we extend the formalism to account for a two-parameter family of corrections that also include the bosonic string and
