Hi everyone!
I hope you can help me…
I got the data from 2011 of the invariant mass for dimuon from J/psi decay in photonuclear PbPb collision, but I am stuck with the rest which is to get the data of transverse momentum pt and rapidity y.
This needs an expert in root to complete my work. Please if there is a freelancer to connect with me on TeamViewer, I will be grateful.
