$g_μ-2$、$R_K$的暗区与双光子共振

A Dark Sector for $g_μ-2$, $R_K$ and a Diphoton Resonance

Geneviève Bélanger, Cédric Delaunay

摘要:

我们重新审视了一组暗扇区模型,在$B$衰变和μ子异常磁矩观察到的异常的动机,在最近报道的双光子过剩约750 $\,$ GeV的光。解释过剩作为一个标量共振与对称性破缺部门的暗规范组,我们表明,一个双光子截面的几个FB可以容纳,连同异常的$R_K$和$g_μ-2$内的一个最小的暗扇区模型。由此产生的突出的对撞机签名是在宽共振信号的形式进入顶和μ子对低于$\sim1\,$ TeV的最终状态。该模型进一步预测了一个暗物质候选者,但与一个显着不足的遗物密度,除非产生一个适当的非热机制。

英文摘要:

We revisit a set of dark sector models, motivated by anomalies observed in $B$ decays and the muon anomalous magnetic moment, in the light of a recently reported diphoton excess around 750$\,$GeV. Interpreting the excess as a scalar resonance associated with the symmetry breaking sector of a dark gauge group, we show that a diphoton cross section of few fb can be accomodated, together with anomalies in $R_K$ and $g_μ-2$ within a minimal dark sector model. The resulting prominent collider signatures are in the form of wide resonant signals into top and muon pair final states below $\sim1\,$TeV. The model further predicts a dark matter candidate, yet with a significantly underabundant relic density, unless produced by an appropriate non-thermal mechanism.
