The first experimental measurement of the incoherent photonuclear production of J/ψ in ultraperipheral heavy-ion collisions is better explained by the presence of subnuclear quantum fluctuations of the gluon field. Read more
The whopping number of collisions recorded by ALICE during the recent five-week heavy-ion run of the LHC is 40 times greater than the total recorded by the experiment in its previous periods of heavy-ion data taking, from 2010 to 2018: Read More
