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...
The LHCb collaboration presented the first measurement of any B → τX decay at a hadron collider
Measurements of the forward production of top-quark pairs can be used to constrain the gluon parton distribution function.
The results reveal an observed (expected) significance of the signal of 2.2 (0.8)σ, for a Higgs-boson mass of 125 GeV.
ATLAS has released new measurements of mtop using events with one or two isolated charged leptons and jets in the final state.
The COMPASS collaboration has recently observed the existence of an unusual meson made from light quarks.
An international team has at last succeeded in producing a neutral electron–positron plasma in a terrestrial laboratory experiment.
Ground-breaking on the way to a new experiment at Fermilab to look for the neutrinoless transformation of a muon into an electron.
The CMS collaboration published two new measurements that provide a comprehensive view of the production of dimuons.
At the recent Moriond Electroweak (EW) conference at La Thuile, the LHCb collaboration presented an updated angular analysis of the decay B → K*0 μ+μ– using the experiment’s full data set f...
