The Romelsberger Index, Berkooz Deconfinement, and Infinite Families of Seiberg Duals

Understand

Romelsberger's index has been argued to be an RG-invariant and, therefore, Seiberg-duality-invariant object that counts protected operators in the IR SCFT of an N=1 theory.

• These claims have so far passed all tests.
• In fact, it remains possible that this index is a perfect discriminant of duality.
• The investigation presented here bolsters such optimism.
