19 Mar 2019, 09:00 → 20 Mar 2019, 21:30 Europe/Berlin

DESY Main Auditorium (Campus Bahrenfeld)

This is the kickoff meeting of the Cluster of Excellence “Quantum Universe” funded by the German Research Foundation (DFG) as part of Germany's Excellence Strategy.

(https://www.qu.uni-hamburg.de)

First day will be plenary in the DESY main auditorium, with a special keynote talk at 16:45, followed by a reception. In the morning of second day, teams from sub-projects will meet in parallel sessions.

16:45 → 17:45 Keynote Talk: "Higgs and the new fundamental interactions"

Particle physicists often talk of four fundamental forces, or interactions: gravity, electromagnetic, weak and strong. Yet particle physicists' standard model has long predicted a new short-range force, associated with the Higgs boson. Unlike the electromagntic, weak and strong forces, its interaction strength does not seem to be a multiple of any underlying basic unit such as the electric charge. Nor does it simply couple to mass in the way that gravity does.

This new "Higgs" force is hypothesised to shape our world in crucial ways, for example ensuring stability of the proton. Yet it is only in the past two years that experiments at the Large Hadron Collider have succeeded in directly observing it. In this talk I will give an overview of what we know of this unique new force, of questions about
it that we know in principle how to answer with future colliders, and of others that we still have no idea how to address.
