Marcello Giorgi of the University of Pisa and Tatsuya Nakada of the Swiss Federal Institute of Technology in Lausanne (EPFL) have been awarded the Enrico Fermi Prize from the Italian Physical Society for their outstanding contributions to the experimental evidence of CP violation in the heavy-quark sector. Giorgi is cited “for his leading role in experimental high-energy particle physics with particular regard to the BaBar experiment and the discovery of CP symmetry violation in the B meson systems with beauty quarks”, while Nakada is recognised for his conception and crucial leading role in the realisation of the LHCb experiment that led earlier this year to the discovery of CP violation in D mesons with charm quarks. The prize was presented on 23 September during the opening ceremony of the 105th national congress of the Italian Physical Society in L’Aquila, Italy.
