In this Letter, 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 world sheet 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 world sheet correlators in conventional bosonic strings (with an arbitrary number of massless and mass-level-one states) and outline a new perspective on massive resonances in string theory.
在这封信中，我们给出了玻色子手征弦（也称为霍姆 - 西格尔 - 茨维巴赫模型）的α′精确背景运动方程，其中自旋 - 2鬼场已被积分掉。这是世界面模型的首个实例，其中所有修正都在一般弯曲时空中完全确定。作为一个具体的交叉检验，我们发现使用场论方法计算的所有三点和四点树图级散射振幅与手征弦规定之间完全一致。这些运动方程为计算传统玻色弦（具有任意数量的无质量和质量一级态）中的世界面关联函数提供了一种场论捷径，并勾勒出弦理论中大量共振的新视角。
