Description

Boosted dark matter is a well-motivated dark matter (DM) model with a small fraction of DM boosted to relativistic energy in astrophysics objects such as the Sun. With the data collected at Super-Kamiokande during 1996-2018 (SKI-IV), we performed a search for boosted dark matter interaction with nucleons. For low boosting region with $\gamma\sim1.5$, the scattering is mostly elastic, and the recoil protons are reconstructed and searched for angular correlation with the direction of the Sun. For $\gamma\gg1$ region, the scattering is dominantly deep inelastic, and the direction is defined by the momenta of all outcoming visible particles. In this poster, we present the sensitivity and the analysis result for boosted dark matter search with hadrons.
