LHCb observes two new strange-beauty baryons
Predicted to exist by the quark model, they are both baryons containing three quarks, in this case, b, s and d.

Nuclei come under the microscope in California
It has long been known that, when they are put under a sufficiently energetic microscope, nuclei reveal a complicated structure – the more energetic the probe, the more complex the structure.

…and investigates suppression of ψ(2S)
Charmonia, bound states of charm and anti-charm quarks, are probes for the formation of hot quark–gluon plasma (QGP) in heavy-ion collisions.

Heavy-ion collisions: where size matters
Results from ALICE provide insight into the size of the final state at “freeze-out” – and a window on collective behaviour.

ALFA in ATLAS measures pp cross-section with high precision
Data from a special run of the LHC using dedicated beam optics at 7 TeV have been analysed to measure the total cross-section of proton–proton collisions in ATLAS.

Precise measurements of top-quark production
The top quark is the heaviest-known fundamental particle, whose mass of about 173 GeV is much larger than that of the other quarks, and comparable to those of the W, Z and Higgs bosons.
