疏轻子Z'和轻重子冷暗物质的双射共振

Dijet resonance from leptophobic Z' and light baryonic cold dark matter

P. Ko, Y. Omura, Chaehyun Yu

摘要:

根据最近CDF关于Wjj沟道过剩的报道,我们分析了(非)超对称U(1)_B × U(1)_L模型,将双喷流峰解释为疏轻子U(1)_B规范玻色子。如果这种过剩被证实,它对模型中的重子冷暗物质(CDM)有一个有趣的含义:应该有几个GeV质量的轻CDM,以及几个x 10^{-2} pb水平的直接探测截面。

英文摘要:

In light of the recent CDF report on the excess in the Wjj channel, we analyze (non)supersymmetric U(1)_B x U(1)_L model, interpreting the dijet peak as a leptophobic U(1)_B gauge boson. If this excess is confirmed, it has an interesting implication for the baryonic cold dark matter (CDM) in the model: there should be light CDM with a few GeV mass, and direct detection cross section at the level of a few x 10^{-2} pb.
