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.
Read article 'Return of the double simplex'
The “double simplex” scheme , which was invented in 2005 by US theorist Chris Quigg, was recently given a flashy makeover by Quanta magazine.
