2. Non-perturbative regime: Strongly coupled DM and quarkonia systems, phase transitions of QCD and new physics particles in the early Universe Tuesday - Session 1

Speaker

Description

I review how strongly coupled potential nonrelativistic QCD (pNRQCD) and lattice
can describe quarkonium in the confinement region. A new effective field theory called Born Effective Field Theory (BOEFT) is able also to describe the new XYZ exotics discovered in the sector with two heavy quarks. I discuss the implications
of these findings for nonperturbative scenarios of DM.
