On the symmetry of TT¯ deformed CFT
Nuclear Physics B, 2020 We propose a symmetry of TT¯ deformed 2D CFT, which preserves the trace relation. The deformed conformal killing equation is obtained. Once we consider the background metric runs with the deformation parameter μ, the deformation contributes an additional

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 ...

Conformal symmetry and the Standard Model
Physics Letters B, 2007 We re-examine the question of radiative symmetry breaking in the standard model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate that, with these extra ingredients, the hypothesis of classically unbroken conformal symmetry, besides naturally introducing and stabilizing a hierarchy, is compatible with all ...

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.

Gravitational dressing of 3D conformal Galileon
Physics Letters B, 2019 Could a conformal Galileon be describing a gauge mode of a broader diffeomorphism invariant theory? We answer this question affirmatively in 3D by using a coset construction for a nonlinearly realized conformal symmetry.

“Kepler Harmonies” and conformal symmetries
Physics Letters B, 2019 Kepler's rescaling becomes, when "Eisenhart-Duval lifted" to $5$-dimensional "Bargmann" gravitational wave spacetime, an ordinary spacetime symmetry for motion along null geodesics, which are the lifts of Keplerian trajectories. The lifted rescaling generates a well-behaved conserved Noether charge upstairs, which takes an unconventional form when ...

Conformal symmetry and the chiral anomaly [PDF]
Physical Review D, 1997 Two-loop contributions to the anomalous correlation function of three chiral currents are calculated by a method based on the conformal properties of massless field theories. The method was previously applied to virtual photon diagrams in quantum electrodynamics, and it is extended here to diagrams with scalars and chiral spinors in the abelian Higgs ...

AdS3 gravity and the complex SYK models
Journal of High Energy Physics, 2021 We provide a non-conformal generalization of the Compère-Song-Strominger (CSS) boundary conditions for AdS3 gravity that breaks the u ̂ 1 $$ \hat{u}(1) $$ Kac-Moody-Virasoro symmetry to two u(1)s.

Conformal Bootstrap Dashing Hopes of Emergent Symmetry
, 2016 We use the conformal bootstrap program to derive necessary conditions for emergent symmetry enhancement from discrete symmetry (e.g. $\mathbb{Z}_n$) to continuous symmetry (e.g. $U(1)$) under the renormalization group flow.
