Invariant mass of $\pi^+\pi^-\pi^0$ candidates shown in the vicinity of the nominal mass of the $\omega$ meson for the indicated $p_{\text{T}}$-range for $\pi^0$ reconstruction with PCM.
Detail description
Invariant mass of $\pi^+\pi^-\pi^0$ candidates shown in the vicinity of the nominal mass of the $\omega$ meson for the indicated $p_{\text{T}}$-range for $\pi^0$ reconstruction with PCM. The second order polynomial used for the background description is shown with a band denoting the statistical uncertainties of the fit. The points show the signal obtained after subtraction of the background fit. The signal is fitted with a Gaussian, where the vertical lines indicate the integration range used to obtain the raw yield by bin-by-bin counting
