Accidental symmetries and the conformal bootstrap [PDF]
Journal of High Energy Physics, 2016 We study an ${\cal N} = 2$ supersymmetric generalization of the three-dimensional critical $O(N)$ vector model that is described by $N+1$ chiral superfields with superpotential $W = g_1 X \sum_i Z_i^2 + g_2 X^3$. By combining the tools of the conformal bootstrap with results obtained through supersymmetric localization, we argue that this model ...

Extended conformal symmetries [PDF]
Journal of Geometry and Physics, 1993 Written in a nice pedagogical style this article provides a rigorous introduction into the subject of \(W\)-algebras. After a brief review of the basic properties of the Virasoro symmetries, the author discusses the most simple example of a higher-spin extension of the Virasoro algebra, namely the \(W_ 3\)-algebra, and further extends the analysis to ...

Spontaneous conformal symmetry breaking in fishnet CFT
Physics Letters B, 2020 Quantum field theories with exact but spontaneously broken conformal invariance have an intriguing feature: their vacuum energy (cosmological constant) is equal to zero. Up to now, the only known ultraviolet complete theories where conformal symmetry can

Quantum diffeomorphisms and conformal symmetry [PDF]
Physical Review D, 1997 We analyze the constraints of general coordinate invariance for quantum theories possessing conformal symmetry in four dimensions. The character of these constraints simplifies enormously on the Einstein universe $R \times S^3$. The $SO(4,2)$ global conformal symmetry algebra of this space determines uniquely a finite shift in the Hamiltonian ...

Conformal symmetry, chiral fermions and semiclassical approximation
Physics Letters B, 2020 The explicit form of conformal generators is found which provides the extension of Poincare symmetry for massless particles of arbitrary helicity. The helicity 12 particles are considered as the particular example.

A scaling limit for line and surface defects
Journal of High Energy Physics, 2022 We study symmetry-breaking line defects in the Wilson-Fisher theory with O(2N + 1) global symmetry near four dimensions and symmetry-preserving surface defects in a cubic model with O(2N) global symmetry near six dimensions.

Chiral Scale and Conformal Invariance in 2D Quantum Field Theory [PDF]
, 2011 It is well known that a local, unitary Poincare-invariant 2D QFT with a global scaling symmetry and a discrete non-negative spectrum of scaling dimensions necessarily has both a left and a right local conformal symmetry.

Journal of High Energy Physics, 2022 I discuss the 2-flavor Schwinger model with θ = 0 and small equal and opposite fermion masses (or θ = π with equal masses). The massless model has an unparticle sector with unbroken conformal symmetry.

Hidden conformal symmetry in Randall–Sundrum 2 model: Universal fermion localization by torsion
Physics Letters B, 2017 In this manuscript we describe a hidden conformal symmetry of the second Randall–Sundrum model (RS2). We show how this can be used to localize fermions of both chiralities. The conformal symmetry leaves few free dimensionless constants and constrains the
