Higgs-Stueckelberg模型中毫荷电暗物质的天体物理学方面

Astrophysical aspects of milli-charged dark matter in a Higgs-Stueckelberg model

A. L. dos Santos, D. Hadjimichef

摘要:

本文研究了标准模型的一个扩展,其中引入了两个新的矢量玻色子,第一个玻色子$Z'$通过通常的最小耦合耦合到标准模型,在标准模型中产生一个扩大的规范扇区。第二个玻色子$A'$场,在模型的暗区,保持无质量,并产生一个暗光子$γ'$。一个混合的混合方案被认为是基于一个组合的希格斯和Stueckelberg机制。在类康普顿过程中,被WIMP散射的光子被转换成暗光子。在天体物理学的应用中,研究了这一过程,估计了白矮星和中子星对恒星冷却的影响。

英文摘要:

An extension of the Standard Model is studied, in which two new vector bosons are introduced, a first boson $Z'$ coupled to the SM by the usual minimal coupling, producing an enlarged gauge sector in the SM. The second boson $A'$ field, in the dark sector of the model, remains massless and originates a dark photon $γ'$. A hybrid mixing scenario is considered based on a combined Higgs and Stueckelberg mechanisms. In a Compton-like process a photon scattered by a WIMP is converted into a dark photon. This process is studied, in an astrophysical application obtaining an estimate of the impact on stellar cooling of white dwarfs and neutron stars.
