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.

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.
