String worldsheet
WebStrings in this mode couple to the worldsheet curvature of other strings, so their abundance through space-time determines the measure by which an average string worldsheet will be curved. This determines its probability to split or connect to other strings: the more a worldsheet is curved, the higher a chance of splitting and reconnecting it has. WebIn String Theory, a Worldsheet is a two-dimensional manifold which describes the …

We construct the physical vertex operators of these models, and compute an extensive set of novel heavy-light correlators.
WebMar 10, 2024 · We compute a large collection of string worldsheet correlators describing light probes interacting with heavy black hole microstates. The heavy states consist of NS5 branes carrying momentum and/or fundamental string charge. WebMar 15, 2024 · In these examples, the weak coupling regime of the four-dimensional theory is mapped to the weak coupling regime of the worldsheet theory. In addition, we study the classical string zero-modes in flat space and obtain predictions for the worldsheet spectra, which agree with the low-energy spectra of the GLSMs obtained in the localization analysis.

These diagrams appear in question # 22475. Some of them are described in Polchinski vol. 1 (p. 79). WebCreate free online language learning exercises in minutes. Unexpected end of JSON input
In physics, the Polyakov action is an action of the two-dimensional conformal field theory describing the worldsheet of a string in string theory. It was introduced by Stanley Deser and Bruno Zumino and independently by L. Brink, P. Di Vecchia and P. S. Howe in 1976, and has become associated with Alexander Polyakov after he made use of it in quantizing the string in 1981. The action reads where is the string tension, is the metric of the target manifold, is the worldsheet metric, its inverse…
