Broken conformal symmetry and hadronic scaling [PDF]
Physics Letters B, 1973 Abstract High energy, large momentum transfer hadronic reactions are studied in the framework of broken conformal symmetry. Hadrons lie on almost linear Regge trajectories. Inclusive cross section scale as ∼s −2 ( q 2 T s) −4 . Large rates of heavy particle production are predicted.

CONFORMAL SCALING GAUGE SYMMETRY AND INFLATIONARY UNIVERSE [PDF]
International Journal of Modern Physics A, 2005 Considering the conformal scaling gauge symmetry as a fundamental symmetry of nature in the presence of gravity, a scalar field is required and used to describe the scale behavior of the universe. In order for the scalar field to be a physical field, a gauge field is necessary to be introduced.

Scaling and conformal symmetries for plane gravitational waves [PDF]
Journal of Mathematical Physics, 2020 The isometries of an exact plane gravitational wave are symmetries for both massive and massless particles. Their conformal extensions are, in fact, chrono-projective transformations {introduced earlier by Duval et al. [Classical Quantum Gravity 3, 461 (1986); Classical Quantum Gravity 32(17), 175006 (2015)]} and are symmetries for massless particles ...

Scale invariant Einstein-Cartan gravity and flat space conformal symmetry [PDF]
Journal of High Energy Physics, 2023 Abstract We find the conditions under which scale-invariant Einstein-Cartan gravity with scalar matter fields leads to an approximate conformal invariance of the flat space particle theory up to energies of the order of the Planck mass.

Softly broken conformal symmetry and the stability of the electroweak scale [PDF]
Modern Physics Letters A, 2015 We point out a possible mechanism by which the electroweak hierarchy problem can be avoided in the low energy effective quantum field theory. Assuming the existence of a UV complete underlying fundamental theory and treating the cutoff scale Λ of the effective field theory as a real physical scale we argue that the hierarchy problem would be solved if

Conformal symmetry: Towards the link between the Fermi and the Planck scales [PDF]
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 ...

Supersymmetry shielding the scaling symmetry of conformal quantum mechanics [PDF]
Physical Review A, 2020 Renormalization of the inverse square potential usually breaks its classical conformal invariance. In a strongly attractive potential, the scaling symmetry is broken to a discrete subgroup while, in a strongly repulsive potential, it is preserved at quantum level. In the intermediate, weak-medium range of the coupling, an anomalous length scale appears

Scale-invariant breaking of conformal symmetry [PDF]
Journal of Physics A: Mathematical and Theoretical, 2015 Known examples of unitary relativistic scale but not conformal-invariant field theories (SFTs) can be embedded into conventional conformal field theories (CFTs). We show that any SFT which is a subsector of a unitary CFT is a free theory. Our discussion applies to an arbitrary number of spacetime dimensions and explains triviality of known SFTs in four
