  Based on a previous work on scenarios where the Standard Model and dark
matter particles share a common asymmetry through effective operators at early
time in the Universe and later on decouple from each other (not care), in this
work, we study in detail the collider phenomenology of these scenarios. In
particular, we use the experimental results from the Large Hadron Collider
(LHC) to constrain the viable parameter space. Besides effective operators, we
also constrain the parameter space of some representative ultraviolet complete
models with experimental results from both the LHC and the Large
Electron-Positron Collider. Specifically, we use measurements related to jets +
missing transverse energy (MET), di-jets and photon + MET. In the case of
ultraviolet models, depending on the assumptions on the couplings and masses of
mediators, the derived constraints can become more or less stringent. We
consider also the situation where one of the mediators has mass below 100 GeV,
in this case we use the ultraviolet model to construct a new effective operator
responsible for the sharing of the asymmetry and study its phenomenology.
