Until June, SPEAR was operating with beams of energy up to 2.5 GeV so that the total energy in the collision was up to a peak of 5 GeV. The ring was shut down during the late summer to install a new RF system and new power supplies so as to reach about 4.5 GeV per beam....
accompanied by two jets, production rates for particle jets at 2.76 TeV compared with 8 TeV, as well as the production of two photons along with jets. Discovered more than two decades ago, the top quark continues to play a vital role in physics analyses for both measurements and searches, ...
But he also said that further development is dependent on epidemic control, vaccination rates and the resumption of economic activity. "We have been through the COVID-19 pandemic," he said. "Till now, the global economy is still facing a great deal of uncertainty." Global express deliveries ...
Reducing the transverse size of the beams delivered by the injectors and gently increasing the bunch population resulted in a peak luminosity of 2.4 × 1033 cm–2s–1 and some healthy luminosity-delivery rates. Following a reduction in β* in ATLAS and CMS from 1.5 m to 1.0 m...
Sterile suggestion Last week, at Neutrino 2020, the MiniBooNE collaboration reported evidence for an excess 560.6 ± 119.6 electron–neutrino events in their detector (pictured), compared to expected rates. Credit: Fermilab The Fermilab programme will combine three liquid-argon TPCs – a bespoke ne...
