来自有问题的场论的有质量弦

Massive strings from a haunted field theory

Nicholas Carabine, Renann Lipinski Jusinskas

AI总结:

本研究给出玻色手征弦积分掉自旋2鬼场后的α'精确背景运动方程,通过散射振幅交叉验证其正确性,为计算常规玻色弦世界面关联函数提供场论捷径,并为弦论有质量共振研究提供新视角。

摘要:

在本研究中,我们给出了玻色手征弦(也称为Hohm-Siegel-Zwiebach模型)的α'精确背景运动方程,其中已积分掉自旋为2的鬼场。这是世界面模型中首个在一般弯曲时空中所有修正都被完全确定的实例。作为具体的交叉验证,我们发现使用场论方法与手征弦方案计算的所有三点树级散射振幅以及部分四点树级散射振幅完全一致。这些运动方程为计算常规玻色弦(包含任意数量的无质量态和第一质量能级态)中的世界面关联函数提供了场论捷径,并为弦论中的有质量共振勾勒出了新的视角。

英文摘要:

In this work we present the $α'$-exact background equations of motion of the bosonic chiral string (also known as Hohm-Siegel-Zwiebach model), with the spin two ghost fields integrated out. This is the first instance of a worldsheet model in which all corrections are fully determined in a generic curved spacetime. As a concrete cross-check, we find complete agreement between all three-point and a sample of four-point tree level scattering amplitudes computed using field theory methods and the chiral string prescription. These equations of motion provide a field theoretical shortcut to compute worldsheet correlators in conventional bosonic strings (with arbitrary number of massless and mass level one states), and outline a new perspective on massive resonances in string theory.
