Search for Boosted Dark Matter at ProtoDUNE

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. Although features are unique enough to isolate signal events from potential backgrounds, vetoing a vast amount of cosmic background is rather challenging as the detectors are located on the ground. We argue, with a careful estimate, that such backgrounds nevertheless can be well under control by performing dedicated analyses after data acquisition. We then discuss some phenomenological studies which can be achieved with ProtoDUNE, employing a dark photon scenario as our benchmark dark-sector model.Comment: Supplemental material include

Dibenzoatobis[3-(pyrrol-1-ylmeth­yl)pyridine]­zinc(II)

In the title compound, [Zn(C7H5O2)2(C10H10N2)2], the ZnII ion, located on a twofold axis, is coordinated by two N atoms from two 3-(pyrrol-1-ylmeth­yl)pyridine ligands and two O atoms from two benzoate ligands in a distorted tetra­hedral geometry. The pyridine and the pyrrole rings are nearly perpendicular to each other, making a dihedral angle of 84.83 (7)°
