Figure Caption

Figure 1a: The distribution of the specific ionization energy loss (d$E$/d$x$) in the TPC of the candidate tracks compared to the expected value for $^3$He ($n_\sigma^\mathrm{TPC}$) in the $p_\mathrm{T}$ range of 1.5 $\leq \pt < 2.0$ GeV/$c$. The background, which is visible as a slope on the left side of the signal, is fitted with a Gaussian function shown in red to estimate the contamination.
