Compactification of closed bosonic strings

Physical Review Letters, 1986
The boundary conditions of the first-quantized compactified closed bosonic string constrain the eigenvalues of the zero-mode operators. Requiring that internal symmetries result from compactification, we show that the simplest boundary conditions imply that the ``left'' and ``right'' lattices must be self-dual at the first-quantized level.

On the conformal field theories for bosonic strings in PP-waves

, 2008
Recently Kazama and Yokoi (arXiv:0801.1561 [hep-th]) have used a phase-space method to study the Virasoro algebra of type IIB superstring theory in the maximally supersymmetric R-R plane wave background in a semi-light-cone gauge.

The Bosonic String

1990
The starting point of dual string theories was the scattering amplitude proposed by Veneziano in 1968 for four neutral scalar particles. The (s,t) term of such an amplitude is given by the well-known Veneziano formula (1): $${\text{A(s,t) = }}\frac{{\Gamma ( - {\alpha _{\text{s}}}){\text{ }}{\mkern 1mu} \Gamma ( - {\alpha _{\text{t}}})}}{{\Gamma ( -

Scattering of D0-branes and Strings

Journal of High Energy Physics
It has been known for about thirty years that a scattering amplitude involving D0-branes and closed strings suffers from infrared divergences beyond tree level.

Non-relativistic quantum strings from gauged WZW models

Journal of High Energy Physics
We construct non-relativistic quantum strings from gauged Wess-Zumino-Witten (WZW) models. We depart from the fact that Lie groups with a bi-invariant galilean structure can be seen as the quotient by a null central subgroup of a generalised Nappi-Witten

BOSONIC STRING WITH TOPOLOGICAL TERM

Modern Physics Letters A, 1991
It is shown that in D = 3 space-time dimensions there exist a topological term for the bosonic strings. The corresponding constraints satisfy the same Virasoro algebra as the ordinary bosonic strings. These results are generalized for an arbitrary dimensional space-time if we have SO (1, 2) ⊗ O (D − 3) or SO (3) ⊗ O (1, D − 4) symmetry instead of SO ...

The Quantized Bosonic String

2012
In this chapter the quantization of the bosonic string is discussed. This leads to the notion of a critical dimension (d= 26) in which the bosonic string can consistently propagate. Its discovery was of great importance for the further development of string theory.
