Abstract

We systematically study models with light scalar and pseudoscalar dark matter candidates and their potential signals at the LHC. First, we derive cosmological bounds on models with the Standard Model Higgs mediator and with a new weak-scale mediator. Next, we study two processes inspired by the indirect and direct detection process topologies, now happening inside the LHC detectors. We find that LHC can observe very light dark matter over a huge mass range if it is produced in mediator decays and then scatters with the detector material to generate jets in the nuclear recoil.

Author comments upon resubmission

We have addressed the issues raised by the referees in a separate PDF file, which is attached as a reply to the referee report.

List of changes

As also outlined in our reply PDF we have additionally added a paragraph concerning potential contributions to N_eff in the early universe of light (pseudo-)scalar DM.
