Generalized Goldstone theorem: Automatic imposition of the Higgs mechanism and application to scale and conformal symmetry breaking [PDF]
Journal of Mathematical Physics, 2001 Standard discussions of Goldstone’s theorem based on a symmetry of the action assume constant fields and global transformations, i.e., transformations which are independent of spacetime coordinates. By allowing for arbitrary field distributions in a general representation of the symmetry we derive a generalization of the standard Goldstone’s theorem ...

Poincaré, Scale and Conformal Symmetries: Gauge Perspective and Cosmological Ramifications [PDF]
, 2016 Symmetries are omnipresent and play a fundamental role in the description of Nature. Thanks to them, we have at our disposal nontrivial selection rules that dictate how a theory should be constructed. This thesis, which is naturally divided into two parts, is devoted to the broad physical implications that spacetime symmetries can have on the systems ...

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.

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.

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 ...

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.

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

Evidence of universal conformal invariance in living biological matter. [PDF]
Nat PhysThe emergent dynamics of collective cellular movement are typically thought to depend on how cells interact with one another and the mechanisms used to drive motility, both of which exhibit remarkable diversity across different biological systems.
