Read article 'High Luminosity LHC moves forward'
October 2015 was a turning point for the High Luminosity LHC (HL-LHC) project, marking the end of the European-funded HiLumi LHC Design Study activities, and the transition to the construction phase, ...
Read article 'A new record for the RMC test magnet at CERN'
High magnetic fields are the Holy Grail of high-energy accelerators. The strength of the dipole field determines the maximum energy the beam can achieve on a given orbit, and large-aperture, high-grad...
Read article 'CMS data-scouting and a search for low-mass dijet resonances'
Proton beams crossed inside each of the CMS and ATLAS detectors 20 million times a second during the 2012 LHC proton–proton run. However, the physics programme of CMS is based on only a small subse...
Read article 'LHCb measures the effective double parton scattering cross-section with unprecedented precision'
In high-energy hadron–hadron collisions, each incoming hadron behaves as a loosely bound system of massless partons – quarks, antiquarks and gluons. The interaction of incoming hadrons is describe...
Read article 'ATLAS observes long-range elliptic anisotropies in √s = 13 and 2.76 TeV pp collisions'
Measurements of two-particle angular correlations in proton–proton (pp) collisions at the LHC have shown a feature commonly called the “ridge”: an enhancement in production of particle p...
Read article 'ALICE looks to the skies (part II)'
The ALICE experiment, designed for the LHC heavy-ion programme, is particularly well-suited for the detection and study of very high-energy cosmic events. The apparatus is located in a cavern 52 m un...
Read article 'Eleven-year search misses gravitational waves'
A pair of supermassive black holes (SMBHs) in close orbit around each other are expected to produce gravitational waves. The background “rumble” of gravitational waves resulting from many ...
Read article 'A wealth of data for physics from the LHC: 1400 colliding bunches per beam and counting'
Thanks to the work done during the LHC machine-development period and technical stop at the end of the summer, the LHC is enjoying a stable-intensity ramp-up period, which is giving experiments precio...
Read article 'CMS observes long-range correlations in pp collisions at 13 TeV'
The CMS collaboration has published its first particle-correlation result from proton–proton (pp) collisions at a centre-of-mass energy of 13 TeV. The paper describes the observation of a phenomeno...
Read article 'Supersymmetry searches: the most comprehensive ATLAS summary to date'
ATLAS has summarised 22 Run 1 searches, using more than 310,000 models to work out where the elusive SUSY particles might be hiding. The first run of the LHC taught us at least two significa...
