### Description

The NA61/SHINE hadron physics program focuses on a search for the critical point and on studies of the properties of the onset of deconfinement in strongly interacting matter. For this purpose the phase diagram is scanned by changing the collision energy (from 13A to 150/158A GeV/c) and the size of the colliding system (from p+p to Pb+Pb).

The main topic of this talk are preliminary results on $K^*(892)^0$ and $\overline{K^*}(892)^0$ meson production in p+p interactions at beam momentum 40-158 GeV/c obtained by the NA61/SHINE experiment. The analysis of $K^*(892)^0$ was performed with a novel template method in the $K^+\pi^-$ decay channel. The results include the double differential spectra $d^2n/(dydp_T)$, $d^2n/(m_Tdm_Tdy)$ as well as yields dn/dy. The measured mass of the $K^*(892)^0$ as a function of transverse momentum is also presented and compared to other published results. Finally, the multiplicity of $K^*(892)^0$ and the ratio of <$K^*(892)^0$>/<$K^{+/-}$> as a function of system size will be presented together with the results from other experiments.
