Measurement of the polarizations of prompt and non-prompt J/$\ddot{I}ˆ$ and $\ddot{I}ˆ$(2S) mesons produced in pp collisions at $\sqrt{s}$ = 13 TeV

The polarizations of prompt and non-prompt J$/\ddot{I}ˆ$ and $\ddot{I}ˆ$(2S) mesons are measured in proton-proton collisions at $\sqrt{s}$ = 13 TeV, using data samples collected by the CMS exper…
