Welcome to the summer issue of CERN Courier, which has a focus on neutrinos. Today, a new generation of reactor and accelerator experiments – including megaprojects DUNE in the US and Hyper-Kamiokande in Japan – are gearing up to complete the measurements of neutrino-oscillation parameters, while a series of shorter baseline experiments are scrutinising the three-neutrino paradigm. The 2020 update of the European strategy for particle physics, released on 19 June, identifies an electron–positron Higgs factory as the highest priority collider after the LHC and urges Europe to explore the feasibility of a future energy-frontier hadron collider with a Higgs factory as a possible first stage. These are exciting times, and this month’s Viewpoint calls on particle physicists to highlight the broad socioeconomic impact of our field. Also in this issue: GNOME homes in on exotic fields; neutron facilities prepare to study SARS-CoV-2; graphene-based Hall probes trialled at CERN; reports on the virtual IPAC and LHCP events; CLOUD breaks new ground in atmospheric science; and much more.
