卡-尤杂种优势复合体结构的稳定化

Stabilizing the Complex Structure in Heterotic Calabi-Yau Vacua

Lara B. Anderson, James Gray, Andre Lukas, Burt Ovrut

摘要:

在本文中,我们表明,存在的规范场的杂合卡-丘紧化的原因稳定的一些,或全部,复杂的结构模的卡-丘流形,同时保持闵可夫斯基真空。卡-丘复结构的某些变形,在所有其他模保持不变的情况下,可以导致规范丛成为非全纯的,因此是非超对称的。这导致了一个F项的潜力,稳定相应的复杂的结构模量。我们使用10-和4-维场论的参数,以及纯粹基于代数几何的推导表明,这幅图确实是正确的。一个明确的例子,其中复杂的结构模量的一个大的子集是固定的。我们证明,这种类型的理论可以作为杂合真空中的隐藏部门,并可以与现实的粒子物理学共存。

英文摘要:

In this paper, we show that the presence of gauge fields in heterotic Calabi-Yau compacitifications causes the stabilisation of some, or all, of the complex structure moduli of the Calabi-Yau manifold while maintaining a Minkowski vacuum. Certain deformations of the Calabi-Yau complex structure, with all other moduli held fixed, can lead to the gauge bundle becoming non-holomorphic and, hence, non-supersymmetric. This leads to an F-term potential which stabilizes the corresponding complex structure moduli. We use 10- and 4-dimensional field theory arguments as well as a derivation based purely on algebraic geometry to show that this picture is indeed correct. An explicit example is presented in which a large subset of complex structure moduli is fixed. We demonstrate that this type of theory can serve as the hidden sector in heterotic vacua and can co-exist with realistic particle physics.
