The year 2015 began for the ATLAS experiment with an intense phase of commissioning using cosmic-ray data and first proton–proton collisions, allowing ATLAS physicists to test the trigger and detect...
Read article 'First results at 13 TeV and more from Run 1'
The highlight of EPS-HEP 2015 for the CMS collaboration was the publication of the first physics result exploring the new territory at the LHC energy of 13 TeV: the measurement of the charged-hadron ...
Read article 'J/ψ mesons, b decays and more'
At EPS-HEP2015, the LHCb collaboration presented the first measurement of the J/ψ production cross-section in proton–proton (pp) collisions at 13 TeV. Using this measurement, they also...

PAUCam, the camera for the Physics of the Accelerating Universe (PAU) project, has been successfully installed and commissioned at the William Herschel Telescope (WHT) at the Roque de los Muchachos Ob...
Read article 'Fermilab sets neutrino-beam record'
In June, Fermilab’s Main Injector accelerator sustained a 521 kW proton beam, and set a world record for the production of high-energy neutrinos with a proton accelerator. The 120 GeV ...
Read article 'Do magnetars power hour-long gamma-ray bursts?'
Based on optical observations, a team of astronomers has, for the first time, demonstrated a link between a very long-lasting gamma-ray burst (GRB) and an unusually bright supernova explosion. The res...
Read article 'LHCf makes the most of a special run'
The motivation of LHCf is to understand the hadronic interactions taking place when high-energy cosmic rays collide with the Earth’s atmosphere.
Read article 'Stable beams at 13 TeV'
At 10.40 a.m. on 3 June, the LHC operators declared “stable beams”, signalling the official start of Run 2.
