The Bosonic Ancestor of Closed and Open Fermionic Strings [PDF]

, 2002
We review the emergence of the ten-dimensional fermionic closed string theories from subspaces of the Hilbert space of the 26-dimensional bosonic closed string theory compactified on an $E_8\times SO(16)$ lattice.

Pohlmeyer reduction for superstrings in AdS space

, 2012
The Pohlmeyer reduced equations for strings moving only in the AdS subspace of AdS_5 x S^5 have been used recently in the study of classical Euclidean minimal surfaces for Wilson loops and some semiclassical three-point correlation functions.

Gravitating Semilocal strings

, 2009
We discuss the properties of semilocal strings minimally coupled to gravity. Semilocal strings are solutions of the bosonic sector of the Standard Model in the limit $\sin^2\theta_W=1$ (where $\theta_W$ is the Weinberg angle) and correspond to embedded ...

Second order bosonic string effective action from O(d, d)

Journal of High Energy Physics
The corrections to the tree-level effective action for the bosonic string up to second order in α ′ are fixed by requiring its dimensional reduction to 26 – d dimensions to be compatible with O(d, d) symmetry.

TFD Approach to Bosonic Strings and $D_{P}$-branes

, 2003
In this work we explain the construction of the thermal vacuum for the bosonic string, as well that of the thermal boundary state interpreted as a $D_{p}$-brane at finite temperature.

Veneziano and Shapiro-Virasoro amplitudes of arbitrarily excited strings

Journal of High Energy Physics
We extend the Veneziano and Shapiro-Virasoro amplitudes to four arbitrarily excited states in bosonic string theory. We use the formalism of coherent string states based on the Di Vecchia-Del Giudice-Fubini construction.

Relations between closed string amplitudes and mixed string amplitudes at tree-level

Journal of High Energy Physics
This paper investigates the relationships between closed and mixed string amplitudes at the tree level in string theory. Through the analytic continuation of complex variables, we establish a factorization of closed string amplitudes into those involving

Celestial holography from chiral strings

Journal of High Energy Physics
In this paper, we studied the relationship between celestial holography and chiral strings. Chiral strings differ from the usual string theory by a change of boundary conditions on the string propagators.
