Connection between particles a field in string theory

Click For Summary

Discussion Overview

The discussion centers on the relationship between strings and fields in string theory, specifically exploring whether a field can be considered analogous to a brane and how these concepts relate to particles.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions how the string entity relates to its underlying field, suggesting a potential analogy between fields and branes.
  • Another participant asserts that a brane is not analogous to a field, clarifying that a string is a one-dimensional object while a D-brane is a D-dimensional object.
  • A similar assertion is made again regarding the distinction between branes and fields, emphasizing the dimensionality of these objects.
  • One participant proposes that a brane can be viewed as an analog of space-time with D dimensions, noting that gravitons may exist on branes while other standard model particles cannot.
  • A participant reiterates their initial question about the relationship between strings and fields, referencing an external link for further clarification.
  • Another participant expresses gratitude for the information provided, indicating that it was helpful.

Areas of Agreement / Disagreement

Participants express disagreement regarding the analogy between branes and fields, with some asserting that they are distinct concepts. The discussion remains unresolved as multiple perspectives are presented without consensus.

Contextual Notes

Some claims depend on specific definitions of branes and fields, and there are unresolved aspects regarding the implications of these distinctions in string theory.

Im a trying to understand how the string entity relates to its underlying field. Is the field a brane and the string the partice?

No. A brane is not the analog of a field, it is another type of object. In the sense that a string is a one-dimensional object (and a particle is a zero-dimensional object), a D-brane is a D-dimensional object.

Thank you.
 
A brane is the analog of space-time with D dimensions, with the caveat that often gravitons can live on branes that other SM particles (i.e. string excitations) are not permitted to be present in.
 
Thank you. That was just what I was looking for!
