Fig. 4.

Transverse momentum spectra ${\mathrm{d}}^{2}N/(\mathrm{d}{p}_{\mathrm{T}}\mathrm{d}y)$ of ${\mathrm{K}}^{\ast 0}$ (a) and $\mathit{\varphi }$ (b) for different multiplicity classes (V0A estimator), measured in the rapidity range $-$0.5 $<$ $y$ $<$ 0. ${\mathrm{K}}^{\ast 0}$ and $\overline{{\mathrm{K}}^{\ast 0}}$ are averaged. The multiplicity-dependent spectra are normalised to the visible cross section, whereas the minimum bias spectrum is normalised to the fraction of NSD events (see text). Statistical (bars) and systematic (boxes) uncertainties are indicated. Dashed lines represent Lévy–Tsallis fits; see text for details
