Supersymmetric U(1)B x U(1)L model with leptophilic and leptophobic cold dark matters
read the original abstract
We consider a supersymmetric model with extra $U(1)_B \times U(1)_L$ gauge symmetry that are broken spontaneously. Salient features of this model are that there are three different types of cold dark matter (CDM) candidates, and neutral scalar sector has a rich structure. Light CDM with $\sigma_{\rm SI} \sim 10^{-3\pm 1}$ pb can be easily accommodated by leptophobic dark matter ($\chi_B$) with correct relic density, if the $U(1)_B$ gauge boson mass is around $2 m_{\chi_B}$. Also the PAMELA and Fermi/LAT data can be fit by leptophilic CDM with mass $\sim 1$ TeV. There could be interesting signatures of new fermions and new gauge bosons at the LHC.

Muonphilic asymmetric dark matter at a future muon collider
Muonphilic portals to fermionic asymmetric dark matter are constrained by existing data and can be probed further by 3 and 10 TeV muon colliders.
