Shang Gao receives SGN Young Scientist Prize
Dr. Shang Gao was awarded the Young Scientist Prize of the Swiss Neutron Scattering Society for his high quality thesis and neutron scattering investigation leading to the discovery of a spiral spin-liquid state in the compound MnSc2S4 and of fast monopole hopping rates in the spin-ice compounds CdEr2X4. The prize is sponsored by Swiss Neutronics and is awarded annualy to a young scientist in recognition of a notable scientific achievement in the form of a PhD thesis.

Claire Donnelly dissertation and research awards
In August 2018, Claire Donnelly was awarded the SPS Award in Computational Physics, sponsored by COMSOL, and the Werner Meyer-Ilse Memorial Award. We congratulate her on these awards as well as for two awards earlier on in the year: the ETH Medal for an outstanding doctoral thesis and the American Physical Society Richard L. Greene Dissertation Award, recognizing doctoral thesis research of exceptional quality and importance. These prizes are for her dissertation on “Hard X-ray Tomography of Three Dimensional Magnetic Structures”.
CMS Young Researcher Prize awarded to Lea Caminada
Lea Caminada, a researcher in the High-Energy Particle Physics group of the Laboratory for Particle Physics (LTP) in NUM, has received the annual CMS Young Researcher Prize. This Prize is given once a year to outstanding young physicists who made very significant and sustained contributions to the CMS experiment at the LHC facility at CERN. Dr. Caminada has been recognized for her contribution to the construction, installation and commissioning of the two pixel detectors which were build at PSI for the CMS experiment. Her work also included the measurement of the B-meson production cross section and the observation of the Higgs boson in association with top quarks.
Observation of ttH Production
The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of √s = 7,8, and 13 TeV, corresponding to integrated luminosities of up to 5.1, 19.7, and 35.9 fb-1, respectively. The data were collected with the CMS detector at the CERN LHC.
Searching for New Physics with b → sτ+τ-
In recent years, intriguing hints for the violation of lepton flavor universality (LFU) have been accumulated in semileptonic B decays, both in the charged-current transitions b → cl-ν-l (i.e., RD, RD∗, and RJ/Ψ and the neutral-current transitions b → sl+l- (i.e., RK and RK∗.
