Seeking the sensational on a small scale
The Swiss Research Magazine 'Horizons' features particle physics performed at PSI.
The Running Bottom Quark Mass and the Higgs Boson
We present a new measurement of the bottom quark mass in the MS scheme at the renormalization scale of the Higgs boson mass from measurements of Higgs boson decay rates at the LHC: mb (mH) = 2.6 +0.36-0.31 GeV. The measurement has a negligible theory uncertainty and excellent prospects to improve at the HL-LHC and a future Higgs factory.
Antiprotons in superfluid helium: a new way for sensitive measurements of antimatter
Scientists, publishing in Nature, have found that a hybrid antimatter-matter atom behaves in an unexpected way when submerged in superfluid helium.
Two million Swiss francs granted to search for new physics
Philipp Schmidt-Wellenburg will set up a novel experiment at a muon beamline at PSI.
