The scattering amplitude of stringy hadrons: strings with opposite charges on their endpoints

Journal of High Energy Physics, 2020
In this note we describe hadrons: mesons and baryons as strings with electric charges on their endpoints. We consider here only the neutral system with opposite charges, coupled to an external constant electromagnetic field.

On the quantization of folded strings in non-critical dimensions

Journal of High Energy Physics, 2020
Classical rotating closed string are folded strings. At the folding points the scalar curvature associated with the induced metric diverges. As a consequence one cannot properly quantize the fluctuations around the classical solution since there is no ...

Quantizing the rotating string with massive endpoints

Journal of High Energy Physics, 2018
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

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.

On realizing the bosonic string as a noncritical W3-string [PDF]

Physics Letters B, 1995
We discuss a realization of the bosonic string as a noncritical $W_3$-string. The relevant noncritical $W_3$-string is characterized by a Liouville sector which is restricted to a (non-unitary) $(3,2)$ $W_3$ minimal model with central charge contribution $c_l = - 2$.

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.

On the positivity of Coon amplitude in D = 4

Journal 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.
