Conformal Spectrum of (Super) Chiral Ising and XY Models

Oleg Antipin, Jahmall Bersini, Jacob Hafjall +2

We determine the spectrum of scaling dimensions of composite operators in the critical Gross-Neveu-Yukawa and Nambu-Jona-Lasinio-Yukawa models through a next-to-leading order semic…

Revisiting the - tension in QCD from a 1PI-action perspective

Paolo Di Vecchia, Francesco Sannino, Graham M. Shore +2

We discuss the tension one encounters in trying to solve, simultaneously, the and strong- problems in QCD with light quarks and a small angle within QCD itself.…

Semiclassical Canovaccio for Composite Operators

Oleg Antipin, Jahmall Bersini, Jacob Hafjall +2

We present a novel semiclassical framework tailored to determine the scaling dimensions of heavy neutral composite operators in conformal field theories (CFTs) which are inaccessib…

Semiclassical spectrum of the Ising CFT

Oleg Antipin, Jahmall Bersini, Jacob Hafjall +2

We develop a semiclassical framework to determine scaling dimensions of neutral composite operators in scalar conformal field theories. For the critical Ising theory in $d=4…

Four-Fermion Deformations on Line Defects in QED with Yukawas

Alessandra D'Alise, Giulia Muco, Francesco Sannino

We elucidate the dynamics induced by a Wilson Line of charge and electron charge in coupled to a real scalar via Yukawa interactions. We observe that there is a ran…

Consistency Relation for Fixed Point Dynamics

Oleg Antipin, Alan Pinoy, Francesco Sannino +1

We gain insight on the fixed point dynamics of dimensional quantum field theories by exploiting the critical behavior of the sister theories. To this end we first derive…

On the -angle physics of QCD under pressure: The strange and isospin phase diagram

Jahmall Bersini, Alessandra D'Alise, Clelia Gambardella +1

We unveil the impact of the -angle on the QCD phase diagram at nonzero isospin and strangeness chemical potentials for three light flavors and different quark mass ratios. We es…

A Temporal Playbook for Multiple Wave Dengue Pandemic from Latin America and Asia to Italy

Alessandra D'Alise, Davide Iacobacci, Francesco Sannino

We show that the epidemiological Renormalization Group (eRG) framework is a useful and minimal tool to effectively describe the temporal evolution of the Dengue multi-wave pandemic…

Exact Results for Scaling Dimensions of Neutral Operators in scalar CFTs

Oleg Antipin, Jahmall Bersini, Francesco Sannino

We determine the scaling dimension for the class of composite operators in the theory in taking the double scaling limit and $λ\rig…

Information index augmented eRG to model vaccination behaviour: A case study of COVID-19 in the US

Bruno Buonomo, Alessandra D'Alise, Rossella Della Marca +1

Recent pandemics triggered the development of a number of mathematical models and computational tools apt at curbing the socio-economic impact of these and future pandemics. The ne…

Defect Induced Heavy Meson Dynamics in the QCD Conformal Window

Vigilante Di Risi, Davide Iacobacci, Francesco Sannino

Upon introducing an heavy quark in the perturbative regime of the QCD conformal window we precisely determine the associated heavy meson spectrum and wave functions in terms of the…

Infinite order results for charged sectors of the Standard Model

Oleg Antipin, Jahmall Bersini, Pantelis Panopoulos +2

We determine anomalous dimensions of a family of fixed hypercharge operators in the Standard Model featuring the general Cabibbo-Kobayashi-Maskawa structure. The results are obtain…

The Dilatonic Dynamics of Baryonic Crystals, Branes and Spheres

Jahmall Bersini, Alessandra D'Alise, Matias Torres +1

We systematically analyze the impact of dilatonic dynamics on Skyrme spheres, crystals and branes. The effects of the dilatonic model parameters, encompassing different underlying…

SM vacuum stability and the Weyl consistency conditions: Counting to three

Jens Krog

We demonstrate how a new perturbative ordering may result from the structure of the Weyl anomaly. Respecting the abelian nature of the Weyl anomaly at the lowest order enforces the…
