Read article 'Large beams take LHC physics forward'
Usually, the motto of the LHC operations team is “maximum luminosity”. For a few days per year, however, this motto is put aside to run the machine at very low luminosity. The aim is to pr...
Read article 'ATLAS homes in on Higgs-quark couplings'
The two heaviest quarks, the bottom and top, are particularly interesting because they have the largest couplings to the Higgs boson.
Read article 'CMS investigates the width of the top quark'
Twenty years after its discovery at the Tevatron collider at Fermilab, interest in studying the top quark at the LHC is higher than ever.
Read article 'LHCb targets new source of CP violation'
The LHCb collaboration presented new results at the 8th International Workshop on Charm Physics (Charm 2016), which took place in Bologna on 5 to 9 September. Among various novelties, the collaboratio...
Read article 'ALICE explores shear viscosity in QCD matter'
One of the key goals in exploring the properties of QCD matter is to pin down the temperature dependence of the shear-viscosity to entropy-density ratio (η/s). In the limit of a weakly interactin...
Read article 'Gaia compiles largest ever stellar survey'
On 13 September, 1000 days after the satellite’s launch, the Gaia team published a preliminary catalogue of more than a billion stars.
Read article 'Proton-radius puzzle deepens'
The international CREMA (Charge Radius Experiment with Muonic Atoms) collaboration has measured the radius of the deuteron more accurately than ever before, finding that it is significantly smaller th...
Read article 'DIRAC experiment observes new exotic atom'
Inclusive πK production via the interaction p + Ni → π−K+ + X. The ionisation or break up of AKπ leads to so-called atomic pairs. Image credit: arXiv:1605.06103v1. The DIRAC (DIm...
Read article 'AMS reports unexpected result in antiproton data'
AMS has now measured the antiproton flux and the antiproton-to-proton flux ratio in primary cosmic rays with unprecedented precision.
Read article 'LHC hits 2016 luminosity target'
At the end of August, two months ahead of schedule, the integrated luminosity delivered by the LHC reached the 2016 target value of 25 fb–1 in both the ATLAS and CMS experiments. The milest...
