我们研究了在具有恒定h通量的平坦背景下及其t对偶结构中传播的闭玻色子弦。我们定义了一个保形场理论,捕捉了通量中的线性效应,并计算了速子的散射振幅,其中罗杰斯二对数起着突出的作用。对于四速子的散射,导出了一种流体版本的Virasoro-Shapiro振幅,并分析了其极点结构。在经过三个t对偶得到的r -通量背景的情况下,我们发现了一个非结合的目标空间结构的指示,该结构可以用变形的三积来描述。值得注意的是,该乘积与共形相关函数的交叉对称是相容的。我们最后论证了r -通量背景流向非对称CFT。
We study closed bosonic strings propagating both in a flat background with constant H-flux and in its T-dual configurations. We define a conformal field theory capturing linear effects in the flux and compute scattering amplitudes of tachyons, where the Rogers dilogarithm plays a prominent role. For the scattering of four tachyons, a fluxed version of the Virasoro–Shapiro amplitude is derived and its pole structure is analysed. In the case of an R-flux background obtained after three T-dualities, we find indications for a nonassociative target-space structure which can be described in terms of a deformed tri-product. Remarkably, this product is compatible with crossing symmetry of conformal correlation functions. We finally argue that the R-flux background flows to an asymmetric CFT.
