Studies at CERN’s CLOUD experiment reveal that part-per-trillion-by-volume iodine levels in marine regions lead to rapid formation of iodic acid particles
Read article 'ALICE shines light inside lead nuclei'
The collaboration is using the quasi-real photons which accompany ultra-relativistic proton and lead beams to measure the photoproduction of charmonia and constrain "nuclear shadowing".
Read article 'LHCb observes four new tetraquarks'
The collaboration has used Run 2 data to add new exotic states to the tally of tetraquarks previously discovered in B+→J/ψφK+ decays in 2016.

High-energy X-rays reveal possible missing neutron star formed by the collapse of the famous supernova's progenitor star.
Read article 'Deep learning tailors supersymmetry searches'
CMS has released a new search for charginos and neutralinos, with sensitivity boosted by the use of parametric machine learning.
Read article 'Farewell Daya Bay, hello JUNO'
As the Daya Bay reactor-neutrino experiment is dismantled, JUNO is gearing up to measure the neutrino mass hierarchy.
Read article 'CMS targets Higgs-boson pair production'
The collaboration has taken an encouraging step towards observing a process with access to the key unknown parameter in the shape of the Brout-Englert-Higgs potential: the self-coupling λ.
Read article 'Higgs boson gets SMEFT treatment'
The move to constrain effective field theories rather than signal strengths for couplings marks a new, more comprehensive phase in Standard Model tests at the LHC.
Read article 'AEgIS on track to test free-fall of antimatter'
Precise knowledge of the moment anti-atoms are produced will allow new tests of the weak equivalence principle.
