Anti-de-Sitter时空中的p-q超弦

p-q-superstrings in Anti-de-Sitter space-time

Betti Hartmann, Momchil Minkov

摘要:

本文研究了固定Anti-de-Sitter背景下p-q超弦的场论模型。我们发现,负宇宙学常数的存在,往往会减少弦的核心半径。而且结合能随宇宙学常数绝对值的增大而减小。通过研究p-q弦对Anti-de-Sitter空间的影响,我们观察到与渐近平坦时空相比,负宇宙学常数的存在会使亏损角减小。

英文摘要:

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.
