We welcome Paolo Crivelli as a new Professor in the group
Dr. Paolo Crivelli, a Senior Scientist in the group since several years, was promoted with the title of Adjoint Professor. Paolo Crivelli is an internationally acclaimed specialist in exotic atoms and dark matter. He investigates these by means of high-precision experiments. He was awarded an ERC Consolidator Grant for his research. We congratulate!!!
PRESS RELEASE : T2K Results Restrict Possible Values of Neutrino CP Phase
Published in Nature, the results are a major step forward in the study of difference between matter and antimatter in the Universe.
Positronium Decays show no evidence of massless Mirror Dark Photons
The origin of the violation of parity symmetry in weak interactions is still a great mystery. Could there be a Mirror world of ours such that overall parity is conserved in Nature? Using our unique positron infrastructure at ETHZ to create positronium, we have searched for its disappearance into its Mirror state. With extremely high sensitivity, we could exclude this process by an order of magnitude compared to previously existing studies. The search for Mirror Matter has been pushed further!
New neutrino interaction cross-section measured in T2K shows discrepancy with expectations
T2K published a new measurement of the differential cross sections of muon neutrino charged-current interactions on carbon with a single positively charged pion. While agreement with the models is generally good, data shows a significant discrepancy in the so-called low Q2 region.
