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-dependence of the $B$-meson LCDA beyond leading order from conformal symmetry [PDF]

Proceedings of 14th International Symposium on Radiative Corrections — PoS(RADCOR2019), 2019
We argue that the evolution kernel for the scale-dependence of the $B$-meson light-cone distribution amplitude (LCDA) can be written, to all orders in perturbation theory, in terms of the generator of special conformal transformations in a modified theory: QCD at critical coupling in non-integer $d\neq 4$ dimensions.

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

Conformal symmetry of a black hole as a scaling limit: a black hole in an asymptotically conical box [PDF]

Journal of High Energy Physics, 2012
We show that the previously obtained subtracted geometry of four-dimensional asymptotically flat multi-charged rotating black holes, whose massless wave equation exhibit $SL(2,\R) \times SL(2,\R) \times SO(3)$ symmetry may be obtained by a suitable scaling limit of certain asymptotically flat multi-charged rotating black holes, which is reminiscent of ...

Conformal Symmetry as a Template:Commensurate Scale Relations and Physical Renormalization Schemes [PDF]

, 1999
Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the ''generalized Crewther relation'', which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum rules to measurements of the e{sup +}e{sup {minus}} annihilation cross section.

Parisi-Sourlas Supertranslation and Scale Invariance without Conformal Symmetry

Physical Review Letters
Inspired by the possibility of emergent supersymmetry in critical random systems, we study a field theory model with a quartic potential of one superfield, possessing the Parisi-Sourlas supertranslation symmetry. Within perturbative ε expansion, we find nine nontrivial scale-invariant renormalization group fixed points, but only one of them is ...
