Four point functions in momentum space and topological terms in gravity
Dimosthenis Theofilopoulos
In the first part, we concentrate on CFTs in coordinate space. We lay the foundations of Conformal Field Theory and we also demonstrate a method where by using the embedding formal…
Topological Corrections and Conformal Backreaction in the Einstein Gauss-Bonnet/Weyl Theories of Gravity at D=4
Claudio Corianò, Matteo Maria Maglio, Dimosthenis Theofilopoulos
We investigate the gravitational backreaction, generated by coupling a general conformal sector to external, classical gravity, as described by a conformal anomaly effective action…
The Conformal Anomaly Action to Fourth Order (4T) in in Momentum Space
Claudio Corianò, Matteo Maria Maglio, Dimosthenis Theofilopoulos
We elaborate on the structure of the conformal anomaly effective action up to 4-th order, in an expansion in the gravitational fluctuations of the background metric, in the f…
Dark Matter with Light and Ultralight Stückelberg Axions
Claudio Corianò, Matteo Maria Maglio, Alessandro Tatullo +1
Scenarios with axion-like particles of variable masses, from the milli-eV range to ultralight, can be generated in a natural way in the context of effective field theory models wit…
The conformal N-point scalar correlator in coordinate space
Nikos Irges, Fotis Koutroulis, Dimosthenis Theofilopoulos
We present a systematic derivation of the form of correlators of N operators in a Conformal Field Theory in d>2 dimensions and the exchange-symmetry constraints that the functions…
Four-Point Functions in Momentum Space: Conformal Ward Identities in the Scalar/Tensor case
Claudio Corianò, Matteo Maria Maglio, Dimosthenis Theofilopoulos
We derive and analyze the conformal Ward identities (CWI's) of a tensor 4-point function of a generic CFT in momentum space. The correlator involves the stress-energy tensor an…
An Axion-Like Particle from an Seesaw with
Claudio Corianò, Paul H. Frampton, Alessandro Tatullo +1
We investigate the decoupling of heavy right handed neutrinos in the context of an SO(10) GUT model, where a remnant anomalous symmetry is . In this model the see-saw mec…
Exact Correlators from Conformal Ward Identities in Momentum Space and Perturbative Realizations
Claudio Corianò, Matteo Maria Maglio, Alessandro Tatullo +1
The general solution of the conformal Ward identities (CWI's) in momentum space, and their matching to perturbation theory, allows to uncover some specific characteristics of the b…
