希格斯粒子衰变为暗物质:超越极小模型

Higgs decays to dark matter: beyond the minimal model

Maxim Pospelov, Adam Ritz

摘要:

我们一方面研究希格斯介导的暗物质湮灭和散射之间的相互作用,另一方面,不可见的希格斯衰变宽度,在一个通用类的模型利用希格斯门户。我们发现,虽然希格斯粒子到暗物质的不可见宽度现在被XENON 100等实验限制为最小的单重标量WIMP,但这一结论在希格斯粒子中介的更一般的例子中并不可靠。我们提出了一个简单的WIMP的m_{DM} < m_h/2和希格斯门调解的情况下,直接检测签名被抑制,而希格斯宽度仍然是由衰变到暗物质占主导地位的调查。

英文摘要:

We examine the interplay between Higgs mediation of dark matter annihilation and scattering on one hand, and the invisible Higgs decay width on the other, in a generic class of models utilizing the Higgs portal. We find that, while the invisible width of the Higgs to dark matter is now constrained for a minimal singlet scalar WIMP by experiments such as XENON100, this conclusion is not robust within more generic examples of Higgs mediation. We present a survey of simple WIMP scenarios with m_{DM} < m_h/2 and Higgs portal mediation, where direct detection signatures are suppressed, while the Higgs width is still dominated by decays to dark matter.
