Off-shell central charge/dimensions in string theory.

Click For Summary

Discussion Overview

The discussion revolves around the concept of off-shell central charge and dimensions in string theory, particularly focusing on the relationship between critical and non-critical strings. Participants explore theoretical implications, potential applications, and the nature of vacuum selection within this framework.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose viewing critical and non-critical strings as aspects of the same theory, suggesting that non-critical strings could provide virtual dimensions that guide vacuum selection.
  • One participant expresses skepticism about the credibility of a referenced paper, noting a lack of external citations and suggesting that it may not be worth studying due to potential errors.
  • Another participant clarifies that their idea regarding the title of the discussion is not directly related to the referenced author's work, but rather suggests it could serve as an attractor in the context of their theory.
  • A participant questions the idea of using non-critical string theory to work directly in four dimensions, seeking clarification on the proposed approach.
  • One participant elaborates on using non-critical strings as a guide for compactification, linking it to the concept of off-shell mass and its implications for critical strings, particularly regarding the conservation of central charge.

Areas of Agreement / Disagreement

Participants express differing views on the relevance and validity of the referenced work, with some supporting the exploration of non-critical strings while others remain skeptical. The discussion does not reach a consensus on the proposed theories or their implications.

Contextual Notes

There are unresolved assumptions regarding the relationship between critical and non-critical strings, as well as the implications of off-shell mass and central charge conservation. The discussion reflects a variety of interpretations and potential applications that remain to be fully explored.

Who May Find This Useful

This discussion may be of interest to researchers and students in theoretical physics, particularly those focused on string theory, compactification, and the interplay between critical and non-critical frameworks.

Instead of thinking of non - critical and critical strings, why not thinking about those as 1 aspect of the same theory, where the non - critical character provides a kind of virtual dimensions. Maybe this could somehow guide a preferential choice of the vaccuum?

For example, this theory, could work as a guide, or attractor:

For 13 years, the first author (B.B. Deo) has been placing papers on the arxiv on this theme, and I found nothing but self-citations for his work. It doesn't inspire confidence that it's worth deciphering; everything suggests that studying the paper will reduce to identifying the places where it goes wrong.
 
The idea of the title was mine. The author's work is not direclty related to that. The only relation is, for example, it would be suited as kind of atractor.

What is the idea? To use noncritical string theory so we can work directly in four dimensions?
 
No, I was thinking use non critical strings as a guide to compactification. For example, consider the concept of off shell mass, which is based in non observable violations of special relativy. Extend that to the critical strings, in which one of the fundamental properties to be conserved is the central charge. So, let it be a sum on c=/=0. And take several values to see if there is a preferential way to fold.
