Abstract In this paper we revisit a generalised crossing equation that follows from harmonic analysis on the conformal group, and is of particular interest for the cosmological bootstrap programme. We present an exact solution to this equation, for d

Abstract We study four-point functions of spinning operators in the flavor current multiplet in four dimensional N $$ \mathcal{N} $$ = 2 SCFTs, using superspace techniques. In particular we explicitly construct the differential operators relating the

Abstract We study a class of two-point functions in a conformal field theory near a wedge. This is a set-up with two boundaries intersecting at an angle θ. We compute it as a solution to the Dyson-Schwinger equation of motion for a quartic interacti

Abstract We start a systematic study of quarter-BPS operators in four-dimensional N $$ \mathcal{N} $$ = 4 Super Yang-Mills with gauge group SU(N) making use of recently developed tools in conformal field theory. We adapt the technology of embedding s

Abstract We initiate the study of one-loop gluon amplitudes in AdS space. These amplitudes were recently computed at tree level for a variety of backgrounds of the form AdS d+1 × S 3. For concreteness, we compute the one-loop correction to the massl

We consider a crossing symmetric dispersion relation (CSDR) for CFT four point correlation with identical scalar operators, which is manifestly symmetric under the cross-ratios $u,v$ interchange. This representation has several features in common wit

Abstract We perform a numerical bootstrap study of the mixed correlator system containing the half-BPS operators of dimension two and three in N $$ \mathcal{N} $$ = 4 Super Yang-Mills. This setup improves on previous works in the literature that only

Abstract We present a dispersion relation in conformal field theory which expresses the four point function as an integral over its single discontinuity. Exploiting the analytic properties of the OPE and crossing symmetry of the correlator, we show t

Abstract We explore and exploit the relation between non-planar correlators in N $$ \mathcal{N} $$ = 4 super-Yang-Mills, and higher-genus closed string amplitudes in type IIB string theory. By conformal field theory techniques we construct the genus-

Abstract We propose a method to analytically solve the bootstrap equation for two point functions in boundary CFT. We consider the analytic structure of the correlator in Lorentzian signature and in particular the discontinuity of bulk and boundary c
