Magnetic quivers from brane webs with O7+-planes

We consider the Higgs branch of 5d fixed points engineered using brane webs with an O7(+)-plane. We use the brane construction to propose a set of rules to extract the corresponding magnetic quivers. Such magnetic quivers are generically framed non-simply-laced quivers containing unitary as well as special unitary gauge nodes. We compute the Coulomb branch Hilbert series of the proposed magnetic quivers. In some specific cases, an alternative magnetic quiver can be obtained either using an ordinary brane web or a brane web with an O5-plane. In these cases, we find a match at the level of the Hilbert series.

Automated summary

We explore the Higgs branch of 5d fixed points engineered using brane webs with an O7(+)-plane, proposing rules to extract magnetic quivers and calculating the Coulomb branch Hilbert series of these quivers. In some cases, alternative magnetic quivers can be obtained using ordinary brane webs or brane webs with an O5-plane, with a matching Hilbert series found.
