可观测的重希格斯暗物质

Observable Heavy Higgs Dark Matter

Venus Keus, Stephen F. King, Stefano Moretti, Dorota Sokolowska

摘要:

暗物质(DM),由惰性希格斯双重粒子产生,可能是轻的,低于$W$质量,也可能是重的,高于525 GeV。虽然轻区域可能很快就会被排除在外,但重区域是已知的,无论是直接探测(DD)实验还是大型强子对撞机(LHC)都很难探测。我们发现,添加第二个惰性希格斯双重有助于使重DM区访问DD和大型强子对撞机,通过增加其耦合到观察到的希格斯玻色子,或降低其质量到$360 \gev \lesssim m_{DM}$,或两者兼而有之。

英文摘要:

Dark Matter (DM), arising from an Inert Higgs Doublet, may either be light, below the $W$ mass, or heavy, above about 525 GeV. While the light region may soon be excluded, the heavy region is known to be very difficult to probe with either Direct Detection (DD) experiments or the Large Hadron Collider (LHC). We show that adding a second Inert Higgs Doublet helps to make the heavy DM region accessible to both DD and the LHC, by either increasing its couplings to the observed Higgs boson, or lowering its mass to $360 \gev \lesssim m_{DM}$, or both.
