Is the Standard Model about to crater?
There are now quite a few discrepancies, or “tensions”, between laboratory experiments and the predictions of the Standard Model (SM) of particle physics. All of them are of the 2...

In 1964, Murray Gell-Mann and George Zweig independently predicted a substructure for hadrons: baryons would be comprised of three quarks, mesons of a quark–antiquark pair. They also said that b...
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.
