探討暗作用力U(1)_D 的現象學，包括異常耦合量子場論以及與粒子物理實驗之比較。

The U(1)D gauge sector containing one dark Higgs boson hD and one dark photon gammaD may be explored through the decays of the 126 GeV particle discovered at the Large Hadron Collider (LHC), assumed here as the heavier mass eigenstate h1 in the mixing of the standard model h with hD. The various decays of h1 to gammaD gammaD, h2 h2, h2 gammaD gammaD and h2 h2 h2 would yield multilepton final states through the mixing of gammaD with the photon and the decay h2 to gammaD gammaD, where h2 is the lighter dark Higgs. Future searches for signals of multilepton jets at the LHC may reveal the existence of this possible dark sector governed simply by the original Abelian Higgs model.

Non-Standard Model(SM) massive fermions are also introduced to induce the kinetic mixing between the dark U(1)D and the standard model hypercharge U(1)Y at one loop order. We also compute various three point functions induced by the non-SM fermions at one loop for the neutral gauge and Higgs bosons in the external legs. Experimental constraints on the induced mixing parameter and three point vertices are studied in detail and their implications for future experimental search for a dark U(1)D sector are discussed.
