复曲面SO(10)F理论概况

Wilfried Buchmuller, Markus Dierigl, Paul-Konstantin Oehlmann, Fabian Ruehle

摘要:

具有大统一规范对称性的四维以上超引力理论是弦论中标准模型紫外线完成的重要中间步骤。利用复曲面几何,考虑Mordell-Weil U(1)和离散规范因子,对规范群为SO(10)的六维F理论真空进行了分类和分析.我们确定了这些模型的全部物质谱,包括带电和中性SO(10)单态。仅基于几何,我们计算所有的物质的多重性,并确认取消规范和引力异常的基础空间无关。特别强调的是对称性增强的物质领域的轨迹和频繁出现的超共形点。它们与非复曲面Kähler变形有关,后者有助于计算自由度。我们计算这些理论的异常系数,以及通过使用一个基地独立的爆破过程和超共形物质过渡。最后,我们确定了六维超引力模型,可以产生高尺度超对称性的标准模型,通过进一步紧致化到四维阿贝尔通量背景。

英文摘要:

Supergravity theories in more than four dimensions with grand unified gauge symmetries are an important intermediate step towards the ultraviolet completion of the Standard Model in string theory. Using toric geometry, we classify and analyze six-dimensional F-theory vacua with gauge group SO(10) taking into account Mordell-Weil U(1) and discrete gauge factors. We determine the full matter spectrum of these models, including charged and neutral SO(10) singlets. Based solely on the geometry, we compute all matter multiplicities and confirm the cancellation of gauge and gravitational anomalies independent of the base space. Particular emphasis is put on symmetry enhancements at the loci of matter fields and to the frequent appearance of superconformal points. They are linked to non-toric Kähler deformations which contribute to the counting of degrees of freedom. We compute the anomaly coefficients for these theories as well by using a base-independent blow-up procedure and superconformal matter transitions. Finally, we identify six-dimensional supergravity models which can yield the Standard Model with high-scale supersymmetry by further compactification to four dimensions in an Abelian flux background.
