Boosted Dark Matter Quarrying at Surface Neutrino Detectors
/ Kim, Doojin (CERN) ; Kong, Kyoungchul (Kansas U.) ; Park, Jong-Chul (Chungnam Natl. U.) ; Shin, Seodong (Chicago U., EFI ; IPAP, Seoul ; Yonsei U.)
We propose the idea of "Earth Shielding" to reject cosmic-ray backgrounds, in the search for boosted dark matter at surface neutrino detectors, resulting in the enhancement of the signal-to-background ratio. The identification of cosmic-originating rare signals, especially lacking features, at surface detectors is often considered hopeless due to a vast amount of cosmic-ray-induced background, hence underground experiments are better motivated to avoid such a challenge.

Searching for boosted dark matter at ProtoDUNE
/ Chatterjee, Animesh (Texas U., Arlington) ; De Roeck, Albert (CERN) ; Kim, Doojin (CERN) ; Moghaddam, Zahra Gh. (CERN) ; Park, Jong-Chul (Chungnam Natl. U.) ; Shin, Seodong (Chicago U., EFI) ; Whitehead, Leigh H. (CERN) ; Yu, Jaehoon (Texas U., Arlington)
We propose the first experimental test of the inelastic boosted dark matter hypothesis, capitalizing on the new physics potential with the imminent data taking of the ProtoDUNE detectors. More specifically, we explore various experimental signatures at the cosmic frontier, arising in boosted dark matter scenarios, i.e., relativistic, inelastic scattering of boosted dark matter often created by the annihilation of its heavier component which usually comprises of the dominant relic abundance.

Inelastic Boosted Dark Matter at Direct Detection Experiments
/ Giudice, Gian F. (CERN) ; Kim, Doojin (CERN) ; Park, Jong-Chul (Chungnam Natl. U.) ; Shin, Seodong (Chicago U., EFI ; IPAP, Seoul ; Yonsei U.)
We explore a novel class of multi-particle dark sectors, called Inelastic Boosted Dark Matter (iBDM). These models are constructed by combining properties of particles that scatter off matter by making transitions to heavier states (Inelastic Dark Matter) with properties of particles that are produced with a large Lorentz boost in annihilation processes in the galactic halo (Boosted Dark Matter).

Dark Matter "Transporting" Mechanism Explaining Positron Excesses
/ Kim, Doojin (CERN) ; Park, Jong-Chul (Chungnam Natl. U.) ; Shin, Seodong (Yonsei U. ; Chicago U., EFI)
We propose a novel mechanism to explain the positron excesses, which are observed by satellite-based telescopes including PAMELA and AMS-02, in dark matter (DM) scenarios. The novelty behind the proposal is that it makes direct use of DM around the Galactic Center where DM populates most densely, allowing us to avoid tensions from cosmological and astrophysical measurements.
