Dr. Beem will describe the identification of a supersymmetryprotected subalgebra of the operator algebra of any fourdimensional **N=2** SCFT or six-dimensional (2,0) SCFT that takes the form of a two-dimensional chiral algebra. The structure of this protected chiral algebra reflects the physics of the parent four- or six-dimensional theory in interesting ways. Applications of this structure include the derivation of new unitarity bounds for four-dimensional SCFTs with global symmetries and the computation of three-point functions of half-BPS operators in the (2,0) theories at finite central charge.
