The Stefan Meyer Institute (SMI) is devoted to basic research in the field of subatomic physics. Our research focuses on the study of fundamental symmetries and interactions, in particular:
Precision Experiments at low energies: antihydrogen studies at CERN-AD/CH (hyperfine spectroscopy testing CPT symmetry, ASACUSA collaboration, and measurement of the gravitational interaction of antimatter, AEgIS collaboration), search for violations of the Pauli principle with VIP@LNGS/IT, and precision measurements of the neutron decay with NoMoS@FRM-II/DE.
Hadron Physics: study of QCD in the non-perturbative regime. Experiments using light-quark systems (kaonic atoms and meson nucleon bound states at DAFNE/IT and J-PARC/JP, pionic and η’ bound states at RIKEN/JP and GSI/DE), systems containing heavy quarks (charmonium and other heavy hadrons with BELLE at KEKB/JP and PANDA at FAIR/DE), and di-electrons to study the Quark Gluon Plasma with ALICE at CERN/CH.
In the third focus Advanced Instrumentation we develop detectors as well as cryogenic and UHV systems needed to perform our experiments.
