Multiplicity and rapidity dependence of ${\mathrm{K}}^{\ast }(892{)}^0$ and $\varphi (1020)$ production in p-Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}$ = 5.02 TeV

The transverse-momentum ($p_{\mathrm{T}}$) spectra of ${\mathrm{K}}^{\ast }(892{)}^0$ and $\varphi (1020)$ measured with the ALICE detector up to $p_{\mathrm{T}}$ = 16 GeV/$c$ in the rapidity range $-1.2<y<0.3$, in p-Pb collisions at the center-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\mathrm{N}\mathrm{N}}}$ = 5.02 TeV are presented as a function of charged particle multiplicity and rapidity. The measured $p_{\mathrm{T}}$ distributions show a dependence on both multiplicity and rapidity at low $p_{\mathrm{T}}$ whereas no significant dependence is observed at high $p_{\mathrm{T}}$. A rapidity dependence is observed in the $p_{\rm T}$-integratedyield(d$N$\mathrm{/}d$y$),whereasthemeantransversemomentum($\left< p_{\rm T} \right>$) shows a flat behavior as a function of rapidity. The rapidity asymmetry ($Y_{\mathrm{a}\mathrm{s}\mathrm{y}\mathrm{m}}$) at low $p_{\mathrm{T}}$ ( < 5 GeV/$c$) is more significant for higher multiplicity classes. At high $p_{\mathrm{T}}$, no significant rapidity asymmetry is observed in any of the multiplicity classes. Both ${\mathrm{K}}^{\ast }(892{)}^0$ and $\varphi (1020)$ show similar $Y_{\mathrm{a}\mathrm{s}\mathrm{y}\mathrm{m}}$. The nuclear modification factor ($Q_{\mathrm{C}\mathrm{P}}$) as a function of $p_{\mathrm{T}}$ shows a Cronin-like enhancement at intermediate $p_{\mathrm{T}}$, which is more prominent at higher rapidities (Pb-going direction) and in higher multiplicity classes. At high $p_{\mathrm{T}}$ (> 5 GeV/$c$), the $Q_{\mathrm{C}\mathrm{P}}$ values are greater than unity and no significant rapidity dependence is observed.
