Abstract:
The suppression of J/ψ production caused by the color-screening effect in heavy-ion collisions is considered as an evidence of the creation of quark-gluon plasma.To interpret the observed suppression in heavy-ion collisions, a good understanding of its production mechanism in p+p collisions is needed. However,the production of J/ψ in hadronic collisions remains not fully understood and requires further studies. Recently, J/ψ production in jets was proposed as a useful observable to help explore the J/ψ production mechanism, and to differentiate various J/ψ production models.In this seminar, I will discuss measurements of J/ψ production within a jet from both RHIC and LHC energy.The measurements in p+p collision from both RHIC and LHC indicate different trend and less isolated production than PYTHIA8. The measurement from heavy-ion collisions support an interpretation of jet quenching as a relevant mechanism for J/ψ suppression. The physics implications and comparison between different measurements will be also discussed.
