Kinetic Mixing at Strong Coupling
Michele Del Zotto, Jonathan J. Heckman, Piyush Kumar +2
A common feature of many string-motivated particle physics models is additional strongly coupled U(1)'s. In such sectors, electric and magnetic states have comparable mass, and int…
Chiral Ring Generating Functions & Branches of Moduli Space
James McGrane, Sanjaye Ramgoolam, Brian Wecht
We consider the worldvolume theory of N D3-branes transverse to various non-compact Calabi-Yau spaces, and describe subtleties in the counting of chiral primary operators in such t…
Theories of Class S and New N=1 SCFTs
James McGrane, Brian Wecht
We describe an infinite two-parameter subfamily of theories of class S where dialing one of the parameters interpolates between Gaiotto's T_N theory and a theory of N^2 free hyperm…
Higher Derivative Corrections and Central Charges from Wrapped M5-branes
Marco Baggio, Nick Halmagyi, Daniel R. Mayerson +2
We compute four-derivative corrections to the AdS supergravity actions arising from the near-horizon geometry of N M5-branes wrapped on either one or two Riemann surfaces. This set…
Global Symmetries and N=2 SUSY
Jock McOrist, Ilarion V. Melnikov, Brian Wecht
We prove that N=2 theories that arise by taking n free hypermultiplets and gauging a subgroup of Sp(n), the non-R global symmetry of the free theory, have a remaining global symmet…
S and T for SCFTs
Jonathan J. Heckman, Piyush Kumar, Brian Wecht
We develop a general set of methods for computing the oblique electroweak parameters S and T for bottom-up and top-down motivated scenarios in which the Higgs weakly mixes with a s…
