ICCUB Colloquia: Quarkonium with Effective field theories

ICCUB Colloquia: Quarkonium with Effective field theories Quantum Chromodynamics (QCD) is the sector of the Standard Model of particle physics that describes the strong interaction, deceptively simple to formulate but notoriously difficult to solve. Heavy quarkonium...

Colloquium – History of Quantum Chromodynamics

Colloquium – History of Quantum Chromodynamics In 1971 Gell-Mann and I introduced the color quantum number of the quarks. One year later the exact color symmetry group was interpreted as the gauge group of a new gauge theory, quantum chromodynamics. The self-coupling...

Colloquium – Reading the Record of Ancient Impacts

Colloquium – Reading the Record of Ancient Impacts Debris from asteroids and comets continually bombards the Earth. Large impacts launch ejecta on trajectories that transport it thousands of kilometers from the impact site. These events are recorded in discrete layers...

Cosmological Simulations of Galaxy Formation

Cosmological Simulations of Galaxy Formation We present a suite of simulated galaxies that match a wide range of scaling relations over a large mass range at z=0, and follow the evolution of these relations and confront them with observational constraints. We then...
