Abstract

Studying the ghost contribution to an off-shell vertex in the open bosonic string theory we argue for the existence of twisted ghost fields, compute some of their properties and compare with recent work of Bershadski.

A bosonic representation of the twisted string emission vertex
1988, Nuclear Physics, Section B
We present an explicit construction of the twist fields which create states in the twisted sectors of the Hilbert space in twisted bosonic string models. Such vertex operators have a complicated structure, which intertwines between the various sectors in the theory, and therefore represents a bosonic analogue of the fermion emission vertex which intertwines between the two sectors of the spinning string.
Comments on the algebra of straight, twisted and intertwining vertex operators
1988, Nuclear Physics, Section B
The extent to which the “intertwining” operator, which converts the untwisted or straight bosonic string to a twisted string and vice versa, also enhances the algebra constructed in the two sectors separately is explored. The relationship between the E₈ + E₈ and the so(32) algebras is discussed in the context of the reflection twist, as is the special role of E₈. The possibility of the other twists (particularly of third order) playing a fundamental role in string theory is briefly explored.
