Deformation Quantization of Bosonic Strings [PDF]

Journal of Physics A: Mathematical and General, 2000
Deformation quantization of bosonic strings is considered. We show that the light-cone gauge is the most convenient classical description to perform the quantization of bosonic strings in the deformation quantization formalism.

Entanglement entropy for open bosonic strings on Dp-branes [PDF]

Physics Letters B, 2018
We study the entanglement entropy for open bosonic strings on multiple Dp-branes by using the covariant open string field theory. Choosing one of the spatial coordinates which are tangential to the hyperplane on which Dp-branes are located, we divide the

The action of long strings in supersymmetric field theories

Journal of High Energy Physics, 2019
Long strings emerge in many Quantum Field Theories, for example as vortices in Abelian Higgs theories, or flux tubes in Yang-Mills theories. The actions of such objects can be expanded in the number of derivatives, around a long straight string solution.

Scattering amplitudes of regularized bosonic strings [PDF]

, 2017
We compute scattering amplitudes of the regularized bosonic Nambu-Goto string in the mean-field approximation, disregarding fluctuations of the Lagrange multiplier and an independent metric about their mean values.

Summing Planar Bosonic Strings [PDF]

Nuclear Physics B, 2006
In earlier work, planar graphs of massless phi^3 theory were summed with the help of the light cone world sheet picture and the mean field approximation.

A W-String Realization of the Bosonic String [PDF]

Physics Letters B, 1993
It has recently been shown that the ordinary bosonic string can be represented by a special background of N=1 or N=2 strings. In this paper, it will be shown that the bosonic string can also be represented by a special background of $W$-strings.Comment ...

Scaling behavior of regularized bosonic strings [PDF]

, 2015
We implement a proper-time UV regularisation of the Nambu-Goto string, introducing an independent metric tensor and the corresponding Lagrange multiplier, and treating them in the mean-field approximation justified for long strings and/or when the ...

QUANTUM GEOMETRY OF BOSONIC STRINGS

Physics Letters B, 1981
We develop a formalism for computing sums over random surfaces which arise in all problems containing gauge invariance (like QCD, three-dimensional Ising model etc.). These sums are reduced to the exactly solvable quantum theory of the two-dimensional Liouville lagrangian.

New BPS states from bosonic/heterotic duality

Journal of High Energy Physics
In this paper, we consider the recently proposed bosonic/heterotic duality that relates the heterotic superstrings to the noncritical bosonic string. Although the latter is nonsupersymmetric, it can be viewed as pseudo-supersymmetric in that the theory ...
