Type-B anomaly matching and the 6D (2,0) theory
Abstract We study type-B conformal anomalies associated with 1 2 $$ rac{1}{2} $$ -BPS Coulomb-branch operators in 4D N $$ mathcal{N} $$ = 2 superconformal field theories.When the vacuum preserves the conformal symmetry these anomalies coincide with the two-point function coefficients in the Coulomb-branch chiral ring.They are non-trivial functions
