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...
Read article 'LHCb determines the electroweak mixing angle'
The two most accurate determinations of the angle, carried out at LEP and SLD, are some three standard deviations different.
Read article 'Novel radionuclides to kill cancer'
A new radiolabelled molecule obtained by the association of a 177Lu isotope and a somatostatin-analogue peptide is showing potential as a cancer killer for certain types of tumour. It is being develop...
Read article 'XENON100 sees no evidence of dark-matter interactions with electrons in liquid xenon'
Nearly 400 days of data taken by the XENON collaboration were used to look for the telltale signature of dark matter, an event rate that varies periodically over the course of a year. The null re...
Read article 'Borexino finds evidence of neutrinos produced in the Earth’s mantle'
In July, the Borexino collaboration reported a geoneutrino signal from the Earth’s mantle with 98% C.L. Geoneutrinos are electron antineutrinos produced by β decays of 238U and 232Th c...
