J/ψ spin-alignment measurement in pp collisions at √s = 8 TeV with the ATLAS detector at the LHC
The J/ψ and Υ mesons were discovered about forty years ago. Since then, the study of qq bound states provide significant input for the understanding of quantum chromodynamics (QCD). Although the J/ψ is one of the simplest systems in QCD, it is difficult to describe in detail its production mechanism...
