Figure Caption
Invariant-mass distributions of $\rm{D}^{+}$ candidates and charge conjugates in the $24 <p_{\rm{T}}< 36$ GeV/c interval for a sample of pp collisions at $\sqrt{s}=13$ TeV. The blue curve shows the fit function of a combined signal (gaussian) and background function (exponential), the red dashed line represents the background fit function. The values of mean (mu) and width (sigma) of the signal peak are reported together with the signal counts (S) in the mass interval (mu-3sigma, mu+3sigma).
Detail description
M[K,pi,pi] invariant mass spectrum for pT = [24,36] GeV/c, corresponding to pass1 reconstruction of LHC16k and LHC16l periods, corresponding to pp@13 TeV data collected with the minimum bias kINT7 trigger in 2016. TOF and TPC PID are applied. The tracks are requested to have at least 3 ITS points (including at least 1 in SPD). Topological cuts are applied.
