Read article 'ALPHA presents novel investigation of the effect of gravity on antimatter'
The ALPHA collaboration at CERN has made the first direct analysis of how antimatter is affected by gravity. The ALPHA experiment was the first to trap atoms of antihydrogen, held in place with a stro...
Read article 'CMS hunts for low-mass dark matter'
Astronomical observations – such as the rotation velocities of galaxies and gravitational lensing – show that more than 80% of the matter in the universe remains invisible.
Read article 'CP violation observed in the decays of B0s mesons'
In March 2012, the LHCb collaboration reported an observation of CP violation in charged B-meson decays.
Read article 'First jet measurements with ALICE'
When quarks and gluons (partons) in opposing beams at high-energy hadron colliders meet they can scatter violently to produce correlated showers of particles, or “jets”. In proton–pr...

A new particle accelerator in the UK has achieved a significant electron acceleration milestone.
Read article 'Why do some gamma-ray bursts last hours?'
Three unusually long-lasting stellar explosions discovered by NASA’s Swift satellite represent a new class of gamma-ray bursts (GRBs). Astrophysicists conclude that they probably arose from the ...

The international team running the Alpha Magnetic Spectrometer (AMS) has announced the first results in its search for dark matter.
Read article 'ATRAP makes world’s most precise measurement of antiproton magnetic moment'
The Antihydrogen TRAP (ATRAP) experiment at CERN’s Antiproton Decelerator has reported a new measurement of the antiproton’s magnetic moment made with an unprecedented uncertainty of 4.4 parts pe...
