Figure Caption
Invariant-mass distributions of $\rm{D}_{s}^{+}$ candidates and charge conjugates in the $4<p_{\rm{T}}<6$ 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 and background function, while the red dashed line represents the background fit function.
Detail description
M[K,K,pi] invariant mass spectrum for pT = [4,6] 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. Topological cuts are applied. The left peak corresponds to the D+->K+K-pi+ decay.
