用F理论建模

Model Building with F-Theory

Ron Donagi, Martijn Wijnholt

摘要:

尽管最近在用D膜建立模型方面取得了很大进展,但要找到一个完全令人信服的规范耦合统一的解释仍然是个问题。我们通过考虑F-理论紧化来扩展模型类,这可能更自然地包含统一。我们解释了如何用G通量推导F理论N=1紧化中的带电手征谱和汤川耦合。在一类模型,承认微扰杂种优势,我们表明,F-理论和杂种优势计算匹配。

英文摘要:

Despite much recent progress in model building with D-branes, it has been problematic to find a completely convincing explanation of gauge coupling unification. We extend the class of models by considering F-theory compactifications, which may incorporate unification more naturally. We explain how to derive the charged chiral spectrum and Yukawa couplings in N=1 compactifications of F-theory with G-flux. In a class of models which admit perturbative heterotic duals, we show that the F-theory and heterotic computations match.
