Comments on Bounds on Central Charges in N = 1 Superconformal Theories

چکیده
Abstract The ratio of central charges in four-dimensional CFT s has been suggested by Hofman and Maldacena to lie within an interval whose boundaries are fixed by the number of supersymmetries. We compute this ratio for a set of interacting N = 1 superconformal field theories which arise as RG fixed points of supersymmetric Yang-Mills theories with adjoint and fundamental matter. We do not find violations of the proposed bounds, which appear to be saturated by free field theories.

We derive general bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal andN = 1 superconformal field theories. In any CFT containing a scalar primary φ of dimension d we show that crossing symmetry of 〈φφφφ〉 implies a completely general lower bound on the central charge c ≥ fc(d). Similarly, in CFTs containing a complex scalar charged under global symmetries, we ...
متن کاملCentral charges of N = 2 superconformal field theories in four dimensions
We present a general method for computing the central charges a and c of N = 2 superconformal field theories corresponding to singular points in the moduli space of N = 2 gauge theories. Our method relates a and c to the U(1)R anomalies of the topologically twisted gauge theory. We evaluate these anomalies by studying the holomorphic dependence of the path integral measure on the moduli. We cal...
متن کاملSpheres, Charges, Instantons, and Bootstrap: A Five-Dimensional Odyssey
We combine supersymmetric localization and the conformal bootstrap to study fivedimensional superconformal field theories. To begin, we classify the admissible counterterms and derive a general relation between the five-sphere partition function and the conformal and flavor central charges. Along the way, we discover a new superconformal anomaly in five dimensions. We then propose a precise tri...
متن کاملA holographic computation of the central charges of d = 4 , N = 2 SCFTs
We use the AdS/CFT correspondence to compute the central charges of the d = 4, N = 2 superconformal field theories arising from N D3-branes at singularities in F-theory. These include the conformal theories with En global symmetries. We compute the central charges a and c related to the conformal anomaly, and also the central charges k associated to the global symmetry in these theories. All of...
متن کاملCarving Out the End of the World or ( Superconformal Bootstrap in Six Dimensions )
We bootstrap N = (1, 0) superconformal field theories in six dimensions, by analyzing the four-point function of flavor current multiplets. Assuming E8 flavor group, we present universal bounds on the central charge CT and the flavor central charge CJ . Based on the numerical data, we conjecture that the rank-one E-string theory saturates the universal lower bound on CJ , and numerically determ...
