一种新的CY椭圆纤维化和蝌蚪相消

A new CY elliptic fibration and tadpole cancellation

Sergio L. Cacciatori, Andrea Cattaneo, Bert Van Geemen

摘要:

F-Theory中的Sen极限中的蝌蚪相消是最近由Bauffi和Esole研究的。我们扩展了他们的结果,推广了他们使用的椭圆纤维化,并获得了一个新的情况下,普遍蝌蚪取消,至少在数值上。我们找不到一个实际的森极限具有正确的膜内容,我们认为,这样的极限可能不存在。我们还给出了一个统一的描述的纤维化所使用的Alkiffi和Esole以及一个新的,简单的,纤维化,其中有非小平型纤维。

英文摘要:

Tadpole cancellation in Sen limits in F-theory was recently studied by Aluffi and Esole. We extend their results, generalizing the elliptic fibrations they used and obtaining a new case of universal tadpole cancellation, at least numerically. We could not find an actual Sen limit having the correct brane content, and we argue that such a limit may not exist. We also give a uniform description of the fibration used by Aluffi and Esole as well as a new, simple, fibration which has non-Kodaira type fibers.
