Marek Karliner and Jonathan Rosner ask what makes tetraquarks and pentaquarks tick, revealing them to be at times exotic compact states, at times hadronic molecules and at times both – with much still to be discovered.
Fifty years ago, the discovery of the J/ψ and its excitations sparked the November Revolution in particle physics, giving fresh experimental impetus to the theoretical ideas that would become the Standard Model.
Patrick Koppenburg and Marco Pappagallo survey the 23 exotic hadrons discovered at the LHC so far.
Two recent results may ease the tension between theory and experiment.
Alexander Lenz argues that the charm quark is an experimental and theoretical enigma that has the potential to shed light on the matter–antimatter asymmetry in the universe.
To celebrate the 10th anniversary of Beamline for Schools, the Courier caught up with past winners whose lives were impacted by the competition.
Experts in data analysis, statistics and machine learning for physics came together from 9 to 12 September for PHYSTAT’s Statistics meets Machine Learning workshop.
