Strongly Coupled Sectors in Inflation: Gapped Theories of Unparticles

Yikun Jiang, Guilherme L. Pimentel, Chen Yang

We consider a novel scenario for a strongly coupled spectator sector during inflation, that of a higher dimensional conformal field theory with large anomalous dimensions -- ``unpa…

Baryons, Skyrmions and -periodicity anomaly in chiral and vector-like gauge theories

Stefano Bolognesi, Andrea Luzio, Giacomo Santoni

In this paper, we study the baryons and solitons of chiral and vector-like gauge theories with matter in mixed one and two-index representations. Focusing on the Color-flav…

Classicized dynamics and initial conditions in field theories with fakeons

Damiano Anselmi, Gianluca Calcagni

Theories with purely virtual particles (fakeons) do not possess a classical action in the strict sense, but rather a "classicized" one, obtained by integrating out the fake particl…

On the Asymptotic Nature of Cosmological Effective Theories

Carlos Duaso Pueyo, Harry Goodhew, Ciaran McCulloch +1

Much of our intuition about Effective Field Theories (EFTs) stems from their formulation in flat spacetime, yet EFTs have become indispensable tools in cosmology, where time-depend…

Strongly Coupled Sectors in Inflation: Gapless Theories and Unparticles

Guilherme L. Pimentel, Chen Yang

We compute correlation functions of the primordial density perturbations when they couple to a gapless, strongly coupled sector of spectator fields -- ``unparticles" -- during infl…

Amplitude prescriptions in field theories with complex poles

Damiano Anselmi, Fabio Briscese, Gianluca Calcagni +1

In the context of field theories with complex poles, we scrutinize four inequivalent ways of defining the scattering amplitudes, each forfeiting one or more tenets of standard quan…

Time Evolution of the Symmetry Resolved Entanglement Entropy after a Mass Quench

Federico Rottoli, Michele Mazzoni, Fabio Sailis +1

In this paper we investigate the properties of the symmetry resolved entanglement entropy after a mass quench in the Ising field theory. Since the theory is free and the post-quenc…

The tricritical Ising CFT and conformal bootstrap

Johan Henriksson

The tricritical Ising CFT is the IR fixed-point of theory. It can be seen as a one-parameter family of CFTs connecting between an -expansion near the upper crit…
