5d Superconformal Index with Enhanced E-type Global Symmetry

Monday 30th April 2012 - 11:30 to 12:30
INI Seminar Room 1
We have recently calculated the superconformal index on 5d N=1 supersymmetric theory with SU(2) gauge group and N fundamental hypermultiplets in the conformal limit where the gauge coupling goes to infinite. This index shows as expected that the global symmetry in the conformal limit is enhanced from the flavor SO(2N) symmetry and the global U(1) symmetry for the instanton number to the exceptional group E(N+1).
