Light dark matter showering under broken dark U(1) — revisited
/ Chen, Junmou ; Ko, Pyungwon ; Li, Hsiangnan ; Li, Jinmian ; et al
It was proposed recently that different chiralities of the dark matter (DM) fermion under a broken dark U(1) gauge group can lead to distinguishable signatures at the LHC through shower patterns, which may reveal the mass origin of the dark sector. [...]
