Scientific Highlights and News
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.
Aldo Antognini Adjunct Professor at ETHZ
Aldo Antognini, currently lecturer and senior scientist at both ETH Zurich and the Laboratory for Particle Physics at NUM/PSI was awarded the title of Adjunct Professor at ETH Zurich.
Higgs-boson pair production at LHC: reliable theoretical uncertainties
Researchers at PSI have refined the theoretical prediction for the pair production of Higgs bosons at the LHC and re-analized the related uncertainties resulting in sizable contributions neglected before. This process will be highly relevant at the high-luminosity run of the LHC to measure the Higgs potential directly.
