Non-toric brane webs, Calabi-Yau 3-folds, and 5d SCFTs
Non-toric brane webs, Calabi-Yau 3-folds, and 5d SCFTs
We study webs of 5-branes with 7-branes in Type IIB string theory from a geometric perspective. To any such a web $W$, we attach a log Calabi-Yau surface $(Y,D)$ with a line bundle $L$. We then describe supersymmetric webs, which are webs defining 5d superconformal field theories (SCFTs), in terms …
