CMS identifies Higgs bosons decaying to bottom quarks

The results reveal an observed (expected) significance of the signal of 2.2 (0.8)σ, for a Higgs-boson mass of 125 GeV.

First full jet measurement in Pb–Pb collisions with ALICE

In high-energy collisions at the LHC, quarks and gluons occasionally scatter violently and produce correlated showers of particles, or “jets”. In proton–proton collisions, the rate o...

ATLAS’s paths to the top-quark mass

ATLAS has released new measurements of mtop using events with one or two isolated charged leptons and jets in the final state.

COMPASS observes a new narrow meson

The COMPASS collaboration has recently observed the existence of an unusual meson made from light quarks.

Laser set-up generates electron–positron plasma in the lab

An international team has at last succeeded in producing a neutral electron–positron plasma in a terrestrial laboratory experiment.

RHIC smashes record for polarized-proton collisions at 200 GeV

The Relativistic Heavy Ion Collider at Brookhaven National Laboratory has shattered its own record for producing polarized-proton collisions at 200 GeV

Magnetic fields cast light on black hole’s edge

The Atacama Large Millimetre/submillimetre Array (ALMA) has revealed an intense magnetic field at the base of the relativistic jet powered by a supermassive black hole. Probing the physical conditions...

Proton beams are back in the LHC

After two years of intense maintenance and consolidation, and several months of preparation for the restart, the LHC is back in operation.

SESAME passes an important milestone at CERN

The SESAME project – the Synchrotron-light for Experimental Science and Applications in the Middle East – passed an important milestone at the beginning of April, with the complete assembly and su...
