LHCb constrains ultra-rare muonic B decay
At first glance, measuring fully leptonic decays seems a step too far, since there is only one charged particle as a signature and no reconstructed B-decay vertex.

Exploring how antimatter falls
ALPHA-g and GBAR have begun campaigns to check whether antimatter falls under gravity at the same rate as matter.

Λc+-baryon probes charm-quark hadronisation
This is essential to understand how charm-quark hadronisation is affected by the presence of the quark–gluon plasma.

Doubly strange baryon observed in Japan
Experimental evidence was first reported in the 1970s, but there has been a lingering theoretical controversy about the interpretation of both states.

Plasma lenses promise smaller accelerators
An international team has made an advance towards more compact particle accelerators, demonstrating that beams can be focused via a technique called active plasma lensing without reducing the beam qua...

ATLAS observes scattering of vector bosons
The cross-section of longitudinal weak-boson scattering would diverge, resulting in meaningless values, were it not for the exact cancellation due to Higgs-boson contributions.
