If “dark quarks” from a confining hidden sector are produced at the LHC, they will shower and hadronize to dark sector hadrons, which may decay back to Standard Model particles within the detector, possibly resulting in a collimated spray of particles resembling a QCD jet. In this work we address scenarios in which dark hadrons decay with a measurable small displacement, such that the relevant background is dominated by heavy-flavor jets.

Abstract The recoil threshold of direct detection (DD) experiments limits the mass range of dark matter (DM) particles that can be detected, with most DD experiments being blind to sub-MeV DM particles. However, these light DM particles can be boosted to very high energies via collisions with energetic cosmic ray electrons. This allows dark matter particles to induce detectable recoil in the target of direct detection experiments.

Eyewitnesses report seeing the trails of a bright meteor over central New Zealand. There have been a large number of reports from the major cities of Wellington and Christchurch. This is probably one of the brightest among a series of such meteors, part of a meteor shower. WeatherWatch.co.nz has been receiving a huge number of hits following this event. Eyewitnesses have been sending in photos to the site.
