50th anniversary of the discovery of asymptotic freedom in QCD

Zbigniew Haba: Asymptotic freedom in QFT
I shall discuss first why QFT (like QED) without the asymptotic freedom is in trouble. Then, I show the virtues of theories with the asymptotic freedom: a reliable weak coupling expansion and (possibly) continuum limit of lattice gauge theories.

Pok Man Lo: Nonperturbative QCD in Coulomb Gauge
This talk focuses on the confinement of quarks and gluons in nonperturbative Quantum Chromodynamics (QCD) within the Coulomb gauge framework. We explore the mechanisms underlying confinement and discuss their implications for constructing low-energy effective models.

David Blaschke: Asymptotic freedom and confinement in neutron star matter
The proof of asymptotic freedom in QCD prompted the hypothesis that in the dense interiors of neutron stars quarks should be deconfined and they appear as “giant MIT bag”. I discuss the recent picture of linking confinement and asymptotic freedom in neutron stars.
