有效弦论的协变演算

Covariant Calculus for Effective String Theories

N. D. Hari Dass, Peter Matlock

摘要:

本文发展了一种构造有效弦论的协变演算。描述任意维量子类弦激发的有效弦论,在过去是用共形场论的原理建立的,但不是以一种系统的方式。利用场定义的自由选择,一个特定的场定义是在一个系统的方式,允许一个明确的有效的弦论与明确的共形对称的建设。一个明显不变的描述的Polchinski-Strominger拉格朗日的不可能性证明和它的意义解释。

英文摘要:

A covariant calculus for the construction of effective string theories is developed. Effective string theory, describing quantum string-like excitations in arbitrary dimension, has in the past been constructed using the principles of conformal field theory, but not in a systematic way. Using the freedom of choice of field definition, a particular field definition is made in a systematic way to allow an explicit construction of effective string theories with manifest exact conformal symmetry. The impossibility of a manifestly invariant description of the Polchinski-Strominger Lagrangian is demonstrated and its meaning is explained.
