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].

Conformal blocks in Virasoro and W theories: duality and the Calogero-Sutherland model [PDF]
, 2011 We study the properties of the conformal blocks of the conformal eld theories with Virasoro or W-extended symmetry. When the conformal blocks contain only second-order degenerate elds, the conformal blocks obey second order dierential equations and they ...

Crossing symmetry and Higher spin towers
Journal of High Energy Physics, 2017 We consider higher spin operators in weakly coupled gauge conformal field theories. Crossing symmetry of mixed scalar correlators relates different higher spin towers and we study the consequences for the spectrum and structure constants of higher spin ...

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

Quest for the Dynamical Origin of Mass - An LHC perspective from Sakata, Nambu and Maskawa [PDF]
, 2009 I review the dynamical symmetry breaking (DSB) approach to the Origin of Mass, which is traced back to the original (2008 Nobel prize) work of Nambu based on the BCS analogue of superconductor where mass of nucleon (then elementary particle) arises due ...

Recursion relations for 5-point conformal blocks
Journal of High Energy Physics, 2021 We consider 5-point functions in conformal field theories in d > 2 dimensions. Using weight-shifting operators, we derive recursion relations which allow for the computation of arbitrary conformal blocks appearing in 5-point functions of scalar operators,

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 ...

A tauberian theorem for the conformal bootstrap
Journal of High Energy Physics, 2017 For expansions in one-dimensional conformal blocks, we provide a rigorous link between the asymptotics of the spectral density of exchanged primaries and the leading singularity in the crossed channel. Our result has a direct application to systems of SL(

On local and integrated stress-tensor commutators
Journal of High Energy Physics, 2021 We discuss some general aspects of commutators of local operators in Lorentzian CFTs, which can be obtained from a suitable analytic continuation of the Euclidean operator product expansion (OPE).

Gapless quantum spin chains: multiple dynamics and conformal wavefunctions [PDF]
, 2017 We study gapless quantum spin chains with spin 1/2 and 1: the Fredkin and Motzkin models. Their entangled groundstates are known exactly but not their excitation spectra. We first express the groundstates in the continuum which allows for the calculation
