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…

Semiclassics at the cusp

Jahmall Bersini, Domenico Orlando, Susanne Reffert +1

We study cusped Wilson line operators in the Abelian Higgs model in $d = 4 - ε$ at large external charges. Using a double-scaling limit $Q \to \infty$ , $ε \to 0$ with $Qε$ fix…

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 $λ ϕ^{4}$ theory in $d=4…

Resurgence Analysis of the Nambu-Jona-Lasinio model at large charge

Jahmall Bersini, Simeon Hellerman, Domenico Orlando +1

We study the fixed point of the three-dimensional NJL model in a double-scaling limit where both the charge $Q$ and the number of fermion flavors $N$ become large with a fixed rati…

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

Exact Results for Scaling Dimensions of Neutral Operators in scalar CFTs

Oleg Antipin, Jahmall Bersini, Francesco Sannino

We determine the scaling dimension $Δ_{n}$ for the class of composite operators $ϕ^{n}$ in the $λ ϕ^{4}$ theory in $d = 4 - ε$ taking the double scaling limit $n \to \infty$ and $λ\rig…

Scaling results for charged sectors of near conformal QCD

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

We provide the leading near conformal corrections on a cylinder to the scaling dimension $Δ_{Q}^{*}$ of fixed isospin charge $Q$ operators defined at the lower boundary of the Quant…

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…

The $θ$ -angle and axion physics of two-color QCD at fixed baryon charge. Part I

Jahmall Bersini, Alessandra D'Alise, Francesco Sannino +1

We analyze the impact of the $θ$ -angle and axion dynamics for two-color (in fact any $S p (2 N)$ ) QCD at nonzero baryon charge and as a function of the number of matter fields on the…

Yukawa interactions at Large Charge

Oleg Antipin, Jahmall Bersini, Pantelis Panopoulos

We extend the fixed-charge semiclassical method by computing anomalous dimensions of fixed-charge scalar operators in models with Yukawa interactions. In particular, we discuss the…
