Scientific Highlights and News
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.
Scientists, publishing in Nature, have found that a hybrid antimatter-matter atom behaves in an unexpected way when submerged in superfluid helium.
Philipp Schmidt-Wellenburg will set up a novel experiment at a muon beamline at PSI.
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.
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.
