(In)可见Z'和暗物质

(In)visible Z' and dark matter

摘要:

我们研究的后果的标准模型的扩展包含一个不可见的额外规范组下的SM粒子是中性的。我们表明,有效的运营商,由两个规范组下的重手征费米子充电和连接新的规范部门的标准模型的循环,可以产生一个可行的暗物质候选人。它的湮灭通过伽马射线线产生清晰的可见信号。这将是通过实际实验观察到的这种模型的确凿证据。

英文摘要:

We study the consequences of an extension of the standard model containing an invisible extra gauge group under which the SM particles are neutral. We show that effective operators, generated by loops of heavy chiral fermions charged under both gauge groups and connecting the new gauge sector to the Standard Model, can give rise to a viable dark matter candidate. Its annihilations produce clean visible signals through a gamma-ray line. This would be a smoking gun signature of such models observable by actual experiments.
