Report summarises dark-sector exploration
ATLAS has recently released a summary gathering the results from more than 20 experimental searches for dark matter and a first collider search for dark energy.
First beam at SLAC plasma facility
FACET-II, a new facility for accelerator research at SLAC National Accelerator Laboratory in California, has produced its first electrons. FACET-II is an upgrade to the Facility for Advanced Accelerat...
From fundamental physics to the brain: Karlheinz Meier 1955–2018
A visionary experimental particle physicist and co-founder of the Human Brain Project.
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.
CMS weighs in on flavour anomalies
Recent results from LHCb and other experiments appear to challenge the assumption of lepton-flavour universality.
Gaia finds evidence of old Milky Way merger
Many of the stars appearing in the night sky did not originate from within our galaxy.
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.
Machine powers down until 2021
The Large Hadron Collider’s 2018 proton physics run came to an end on 24 October, having accumulated an impressive dataset. The integrated luminosity delivered to both the ATLAS and CMS experiments...
