Journal ArticleDOI
Renormalization of vacuum expectation values in spontaneously broken gauge theories
TL;DR: In this article, one-loop and two-loop β-functions for vacuum expectation values (VEVs) in gauge theories were computed for generic as well as supersymmetric gauge theories.
Journal ArticleDOI
Renormalization of vacuum expectation values in spontaneously broken gauge theories: Two-loop results
TL;DR: In this paper, the two-loop calculation of β-functions for vacuum expectation values (VEVs) in generic and supersymmetric theories up to 2-loop level in arbitrary R ξν ξ -gauge was presented by using a scalar background field.
Journal ArticleDOI
The Higgs mechanism — Hasse diagrams for symplectic singularities
Antoine Bourget,Santiago Cabrera,Julius F. Grimminger,Amihay Hanany,Marcus Sperling,Anton Zajac,Zhenghao Zhong +6 more
TL;DR: In this paper, the geometrical structure of Higgs branches of quantum field theories with 8 supercharges in 3, 4, 5 and 6 dimensions was explored, and a Hasse diagram was obtained to encode the structure of the foliation.
Journal ArticleDOI
Magnetic Quivers from Brane Webs with O5 Planes
TL;DR: In this paper, the magnetic quiver prescription is derived and contrasted with a unitary magnetic quivers description extracted from an O7− construction. And the results are validated by a derivation of the associated Hasse diagrams.
Journal ArticleDOI
Magnetic quivers, Higgs branches and 6d \( \mathcal{N} = \left(1,\kern0.5em 0\right) \) theories
TL;DR: In this paper, a formalism is introduced that allows to derive a novel object from a brane configuration, called the magnetic quiver, which can be used to describe the Higgs branches at finite and infinite gauge coupling spaces of dressed monopole operators.
