Goal
The main goal of the experiment was to perform a complete study of CP violation (CP is the symmetry linking particules and antiparticules) in the system of B mesons.
More generally the experiment studied the physics of heavy flavors: mesons and baryons with a b or a c quark and tau leptons.
Gravitational Behaviour of Antihydrogen at Rest
Aims:
One of the fundamental questions of today’s physics concerns the action of gravity upon antimatter. No experimental direct measurement had been successfully performed with antimatter particles in the 2010's. CERN has thus launched a research program with the Antiproton Decelerator (AD) allowing to prepare a measurement of the effect of gravity on antihydrogen atoms.
The primary aim of this experiment is to determine how antimatter reacts to gravity.
