A CFT interpretation of cosmological correlation functions in α−vacua in de-Sitter space

open access: yesJournal of High Energy Physics, 2023
De-Sitter(dS) space allows for a generalized class of vacua, known as α–vacua, described by some parameters. The Bunch-Davies (BD) vacuum is a point in this parameter space. The cosmological correlation function in BD vacuum in four dimensions and can be

CONFORMAL SCALING GAUGE SYMMETRY AND INFLATIONARY UNIVERSE [PDF]

open access: yesInternational 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]

open access: yesModern 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

Non-Lorentzian RG flows and supersymmetry

open access: yesJournal of High Energy Physics, 2019
We describe a general process where a non-Lorentzian rescaling of a supersymmetric field theory leads to a scale-invariant fixed point action without Lorentz invariance but where the supersymmetry is preserved or even enhanced. We apply this procedure to

Modular differential equations with movable poles and admissible RCFT characters

open access: yesJournal of High Energy Physics, 2023
Studies of modular linear differential equations (MLDE) for the classification of rational CFT characters have been limited to the case where the coefficient functions (in monic form) have no poles, or poles at special points of moduli space.

Scale invariant Einstein-Cartan gravity and flat space conformal symmetry

open access: yesJournal 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.

An integer basis for celestial amplitudes

open access: yesJournal of High Energy Physics, 2023
We present a discrete basis of solutions of the massless Klein-Gordon equation in 3 + 1 Minkowski space which transform as 𝔰𝔩(2, ℂ) Lorentz/conformal primaries and descendants, and whose elements all have integer conformal dimension.

Hecke relations among 2d fermionic RCFTs

open access: yesJournal of High Energy Physics, 2023
Recently, Harvey and Wu proposed a suitable Hecke operator for vector-valued SL(2, ℤ) modular forms to connect the characters of different 2d rational conformal field theories (RCFTs).
