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.

Scaled pT spectra of charged particles in jets for different bins of jet transverse momentum. “Jets are collimated sprays of particles.” This ubiquitous characterization used in man...
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.
One of the hottest topics at the LHC is the understanding of potential collective effects in proton–lead collisions, prompted by the discovery of ridge structures in angular correlations of part...
Charmonia, bound states of charm and anti-charm quarks, are probes for the formation of hot quark–gluon plasma (QGP) in heavy-ion collisions.
Results from ALICE provide insight into the size of the final state at “freeze-out” – and a window on collective behaviour.
More than 120 physicists from across the world met at CERN to discuss questions related to hadron production in cosmic-ray interactions and at accelerator experiments.
The electric charge of lead ions, when accelerated to ultra-relativistic velocities, is the source of an intense flux of high-energy quasi-real photons.
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.
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.
