Description
K$^*$(892) production from nuclei provides a crucial test ground for exploring possible in-medium modification of K$^*$(892) properties. Recently, we collected high-statistics datasets for $^{12}$C(K$^-$,p) reactions at 1.8 GeV/c. We performed this measurement simultaneously in the J-PARC E42 run for the H-dibaryon search. The HypTPC helps reconstruct the K$^*$(892)-> K$^0_{s}\pi^-$ decay, while a forward spectrometer tags a proton in the angular range 0$^\circ$ < $\theta_{K^-p}$ < 20$^\circ$. This talk will present preliminary results on the differential cross-section measurement for $^{12}$C(K$^-$, p)K$^*$(892)X and p(K$^-$,p)K$^*$(892) at 1.8 GeV/c. Furthermore, the measurement of decay particles from the kaonic-bound region will be also discussed, which can be a good probe for kaonic-bound nuclei.
