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 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 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...

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...
