Journal of High Energy Physics, 2019 We study the Virasoro conformal block decomposition of the genus two partition function of a two-dimensional CFT by expanding around a ℤ3-invariant Riemann surface that is a three-fold cover of the Riemann sphere branched at four points, and explore ...

The Lorentzian inversion formula and the spectrum of the 3d O(2) CFT
Journal of High Energy Physics, 2020 We study the spectrum and OPE coefficients of the three-dimensional critical O(2) model, using four-point functions of the leading scalars with charges 0, 1, and 2 (s, ϕ, and t).

Wronskian indices and rational conformal field theories
Journal of High Energy Physics, 2021 The classification scheme for rational conformal field theories, given by the Mathur-Mukhi-Sen (MMS) program, identifies a rational conformal field theory by two numbers: (n, l). n is the number of characters of the rational conformal field theory.

Cut-touching linear functionals in the conformal bootstrap
Journal of High Energy Physics, 2017 The modern conformal bootstrap program often employs the method of linear functionals to derive the numerical or analytical bounds on the CFT data. These functionals must have a crucial “swapping” property, allowing to swap infinite summation with the ...

Conformal four-point correlation functions from the operator product expansion
Journal of High Energy Physics, 2020 We show how to compute conformal blocks of operators in arbitrary Lorentz representations using the formalism described in [1, 2] and present several explicit examples of blocks derived via this method.

Bound on asymptotics of magnitude of three point coefficients in 2D CFT
Journal of High Energy Physics, 2020 We use methods inspired from complex Tauberian theorems to make progress in understanding the asymptotic behavior of the magnitude of heavy-light-heavy three point coefficients rigorously. The conditions and the precise sense of averaging, which can lead

Classifying three-character RCFTs with Wronskian index equalling 0 or 2
Journal of High Energy Physics, 2021 In the modular linear differential equation (MLDE) approach to classifying rational conformal field theories (RCFTs) both the MLDE and the RCFT are identified by a pair of non-negative integers [n,l].

The analytic bootstrap equations of non-diagonal two-dimensional CFT
Journal of High Energy Physics, 2018 Under the assumption that degenerate fields exist, diagonal CFTs such as Liouville theory can be solved analytically using the conformal bootstrap method. Here we generalize this approach to non-diagonal CFTs, i.e.

Crossing, modular averages and N ↔ k in WZW models
Journal of High Energy Physics, 2019 We consider the construction of genus zero correlators of SU(N ) k WZW models involving two Kac-Moody primaries in the fundamental and two in the anti-fundamental representation from modular averaging of the contribution of the vacuum conformal block. We

Large-c superconformal torus blocks
Journal of High Energy Physics, 2018 We study large-c SCFT2 on a torus specializing to one-point superblocks in the N $$ \mathcal{N} $$ = 1 Neveu-Schwarz sector. Considering different contractions of the Neveu-Schwarz superalgebra related to the large central charge limit we explicitly ...
