Open AccessEffective field theories for dark matter pairs in the early universe: center-of-mass recoil effects
For non-relativistic thermal dark matter, close-to-threshold effects largely dominate the evolution of the number density for most of the times after thermal freeze-out, and hence affect the cosmological relic...

Open AccessComparative study of quarkonium transport in hot QCD matter
This document summarizes the efforts of the EMMI Rapid Reaction Task Force on “Suppression and (re)generation of quarkonium in heavy-ion collisions at the LHC”, centered around their 2019 and 2022 meetings. It...

Open AccessEffective field theories for dark matter pairs in the early universe: cross sections and widths
In order to predict the cosmological abundance of dark matter, an estimation of particle rates in an expanding thermal environment is needed. For thermal dark matter, the non-relativistic regime sets the stage...

Open AccessHeavy-flavor production and medium properties in high-energy nuclear collisions --What next?
Open and hidden heavy-flavor physics in high-energy nuclear collisions are entering a new and exciting stage towards reaching a clearer understanding of the new experimental results with the possibility to lin...

Open AccessCP asymmetry in heavy Majorana neutrino decays at finite temperature: the hierarchical case
We consider the simplest realization of leptogenesis with one heavy Majorana neutrino species much lighter than the other ones. In this scenario, when the temperature of the early universe is smaller than the ...

Open AccessCP asymmetry in heavy Majorana neutrino decays at finite temperature: the nearly degenerate case
In a model where Majorana neutrinos heavier than the electroweak scale couple to Standard Model Higgs bosons and leptons, we compute systematically thermal corrections to the direct and indirect CP asymmetries...

Open AccessQCD and strongly coupled gauge theories: challenges and perspectives
We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical pro...

Renormalization of loop functions in QCD
We give a short overview of the renormalization properties of rectangular Wilson loops, the Polyakov loop correlator and the cyclic Wilson loop. We then discuss how to renormalize loops with more than one inte...

An effective field theory for non-relativistic Majorana neutrinos
Heavy Majorana neutrinos enter in many scenarios of physics beyond the Standard Model: in the original seesaw mechanism they provide a natural explanation for the small masses of the Standard Model neutrinos a...

Heavy quarkonium: progress, puzzles, and opportunities
A golden age for heavy-quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experimental activity. The early year...

Effective field theories for the heavy quarkonium
We briefly review how nonrelativistic effective field theories give us a definition of the QCD potentials and a coherent field-theory-derived quantum-mechanical scheme to calculate the properties of bound stat...

Prospects for e+e- physics at Frascati between the φ and the ψ
We present a detailed study, done in the framework of the INFN 2006 Roadmap, of the prospects for e+e- physics at the Frascati National Laboratories. The physics case for an e+e- collider running at high luminosi...

On the form of the quark-antiquark bethe-salpeter kernel
We obtain a quark-antiquark BS kernel which in the instantaneous approximation reproduces a theoretical based potential including all first-order relativistic corrections and derived in a preceding paper by an...

Relativistic corrections to the quark-antiquark potential and the quarkonium spectrum
The theoretical derivation from QCD of the \(q\bar q\) potential with velocity-dependent corrections is reconsider...
