TL;DR

This paper investigates p-q-superstrings within Anti-de-Sitter space-time, revealing how a negative cosmological constant influences string core size, binding energy, and space-time geometry, with implications for theoretical physics models.

Contribution

It provides a detailed analysis of p-q-superstrings in Anti-de-Sitter space, highlighting the effects of negative cosmological constant on string properties and space-time structure.

Findings

Negative cosmological constant decreases string core radius.

Binding energy of strings diminishes with increasing |Λ|.

Negative Λ reduces the deficit angle compared to flat space.

Abstract

We study a field theoretical model for p-q-superstrings in a fixed Anti-de-Sitter background. We find that the presence of the negative cosmological constant tends to decrease the core radius of the strings. Moreover, the binding energy decreases with the increase of the absolute value of the cosmological constant. Studying the effect of the p-q-strings on Anti-de-Sitter space, we observe that the presence of the negative cosmological constant tends to decrease the deficit angle as compared to asymptotically flat space-time.
