Results have been published in the detector performance note CMS DP-2018/050

Charged pion-track efficiency

deltaM_2b_DATA.pngdeltaM_4b_DATA.png

ΔM=M(D*)-M^(D0) distributions for Kpi (left) and K3pi (right) for data.

The fitted shapes in blue well describe data point for both signal (solid) and background (dashed).

effi_2017.png The ratio of tracking relative efficiencies for charged pions, as a function of the minimum D* candidates pT threshold, is shown in three different pseudorapidity regions: barrel (blue), transition (green) and endcap (red).
effi_2017_PU.png The ratio of tracking relative efficiencies for charged pions as a function of number of vertices in the event is reported. A good stability of the efficiency is shown.
