The study of meson photoproduction on the nucleon is a very important tool to complete the puzzle of baryon excited states. GRAAL aim is the measurement of...
ϒ(nS) polarizations versus particle multiplicity in pp collisions at √{ s} = 7 TeV
The polarizations of the ϒ (1 S) , ϒ (2 S) , and ϒ (3 S) mesons are measured as a function of the charged particle multiplicity in proton-proton collisions at √...
