重塑B模型

Remodeling the B-model

Vincent Bouchard, Albrecht Klemm, Marcos Marino, Sara Pasquetti

摘要:

我们提出了一个完整的,新的形式主义,明确地计算B-模型开放和封闭的振幅在当地的卡-丘几何,包括复曲面流形的镜子。该方法基于Eynard和Orantin最近提出的矩阵模型的递归解。由此产生的振幅是非微扰的封闭和开放的模量。该方法可用于研究开/闭模空间中的弦相变。在大半径时,该形式可以看作是拓扑顶点的镜像形式,但在模空间的其它相也是有效的。我们开发的形式主义一般,并提供了大量的检查,包括测试的orbifold点的A_p纤维化,振幅计算的“t Hooft展开的威尔逊圈在镜头空间。我们还用我们的方法预测了轨道圈C^3/Z_3的圆盘振幅。

英文摘要:

We propose a complete, new formalism to compute unambiguously B-model open and closed amplitudes in local Calabi-Yau geometries, including the mirrors of toric manifolds. The formalism is based on the recursive solution of matrix models recently proposed by Eynard and Orantin. The resulting amplitudes are non-perturbative in both the closed and the open moduli. The formalism can then be used to study stringy phase transitions in the open/closed moduli space. At large radius, this formalism may be seen as a mirror formalism to the topological vertex, but it is also valid in other phases in the moduli space. We develop the formalism in general and provide an extensive number of checks, including a test at the orbifold point of A_p fibrations, where the amplitudes compute the 't Hooft expansion of Wilson loops in lens spaces. We also use our formalism to predict the disk amplitude for the orbifold C^3/Z_3.
