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.

Defect a-theorem and a-maximization
Journal of High Energy Physics, 2022 Conformal defects describe the universal behaviors of a conformal field theory (CFT) in the presence of a boundary or more general impurities. The coupled critical system is characterized by new conformal anomalies which are analogous to, and generalize ...

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.

Neutrinos, axions and conformal symmetry [PDF]
The European Physical Journal C, 2008 We demonstrate that radiative breaking of conformal symmetry (and simultaneously electroweak symmetry) in the Standard Model with right-chiral neutrinos and a minimally enlarged scalar sector induces spontaneous breaking of lepton number symmetry, which naturally gives rise to an axion-like particle with some unusual features.

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

Higher-dimensional symmetry of AdS2×S2 correlators
Journal of High Energy Physics, 2022 It was recently shown that IIB supergravity on AdS5×S5 enjoys 10d conformal symmetry and that superstring theory on this background can be described using a 10d scalar effective field theory.

Conformal symmetry and unification [PDF]
AIP Conference Proceedings, 1998 The Weyl-Weinberg-Salam model is presented. It is based on the local conformal gauge symmetry. The model identifies the Higgs scalar field in SM with the Penrose-Chernikov-Tagirov scalar field of the conformal theory of gravity. Higgs mechanism for generation of particle masses is replaced by the originated in Weyl's ideas conformal gauge scale fixing.
