Probing Light Nonthermal Dark Matter at the LHC

Understand

This paper investigates the collider phenomenolgy of a minimal nonthermal dark matter model with a 1-GeV dark matter candidate, which naturally explain baryongensis.

• Since the light dark matter is not parity-protected, it can be singly produced at the LHC.
• This leads to large missing energy associated with an energetic jet whose transverse momentum distribution is featured by a Jacobian-like shape.
• The monojet, dijet, paired dijet and 2 jets + missing energy channels are studied.
