Conformal symmetry: Towards the link between the Fermi and the Planck scales
Physics Letters B, 2018 If the mass of the Higgs boson is put to zero, the classical Lagrangian of the Standard Model (SM) becomes conformally invariant (CI). Taking into account quantum non-perturbative QCD effects violating CI leads to electroweak symmetry breaking with the scale $v \sim _{\rm QCD}\sim 100$ MeV which is three orders of magnitude less than it is observed ...

The Gross-Neveu-Yukawa archipelago
Journal of High Energy Physics, 2023 We perform a bootstrap analysis of a mixed system of four-point functions of bosonic and fermionic operators in parity-preserving 3d CFTs with O(N) global symmetry. Our results provide rigorous bounds on the scaling dimensions of the O(N)-symmetric Gross-

Duality constructions from quantum state manifolds [PDF]
, 2015 The formalism of quantum state space geometry on manifolds of generalised coherent states is proposed as a natural setting for the construction of geometric dual descriptions of non-relativistic quantum systems.

Dualities between fermionic theories and the Potts model
Journal of High Energy Physics, 2023 We show that a large class of fermionic theories are dual to a q → 0 limit of the Potts model in the presence of a magnetic field. These can be described using a statistical model of random forests on a graph, generalizing the (unrooted) random forest ...

Bootstrapping conformal QED3 and deconfined quantum critical point
Journal of High Energy Physics, 2022 We bootstrap the deconfined quantum critical point (DQCP) and 3D Quantum Electrodynamics (QED3) coupled to N f flavors of two-component Dirac fermions. We show the lattice and perturbative results on the SO(5) symmetric DQCP are excluded by the bootstrap

Axial symmetry and conformal Killing vectors [PDF]
, 1993 Axisymmetric spacetimes with a conformal symmetry are studied and it is shown that, if there is no further conformal symmetry, the axial Killing vector and the conformal Killing vector must commute.

Noether symmetries, energy-momentum tensors and conformal invariance in classical field theory
, 2009 In the framework of classical field theory, we first review the Noether theory of symmetries, with simple rederivations of its essential results, with special emphasis given to the Noether identities for gauge theories.

Notes on a surface defect in the O(N) model
Journal of High Energy Physics, 2023 We study a surface defect in the free and critical O(N) vector models, defined by adding a quadratic perturbation localized on a two-dimensional subspace of the d-dimensional CFT.

Scalar tilt from broken conformal invariance
, 2010 Within recently proposed scenario which explains flatness of the spectrum of scalar cosmological perturbations by a combination of conformal and global symmetries, we discuss the effect of weak breaking of conformal invariance.

The epsilon expansion of the O(N) model with line defect from conformal field theory
Journal of High Energy Physics, 2023 We employ the axiomatic framework of Rychkov and Tan to investigate the critical O(N) vector model with a line defect in (4 − ϵ) dimensions. We assume the fixed point is described by defect conformal field theory and show that the critical value of the ...
