A Higgs Factory is considered the highest priority next collider project by the high-energy physics community. Very advanced designs based on radio-frequency cavities exist, and variations on this approach are still being developed. Recently, an option based on electron-bunch driven plasma wakefield acceleration has also been proposed. In this article, we discuss a further option based on proton-driven plasma wakefield acceleration. This option has significant potential advantages due to the high energy of the plasma wakefield driver, simplifying the plasma acceleration stage. Its success will depend on further developments in producing compact high-energy proton bunches at a high rate, which would also make possible a broad range of synergistic particle-physics research.

125 GeV希格斯工厂（HF）μ子对撞机（MC）的初步设计已经确定了HF探测器上巨大的本底载荷。这与12倍更高的μ介子衰变概率在HF相比，以前研究的1.5 TeV MC。作为MARS 15优化研究的结果，它表明，与精心设计的保护系统中的相互作用区域，在机器探测器接口和探测器内，可以减少背景率到一个可管理的水平，类似于实现优化的1.5-TeV的情况下。HF探测器背景的主要特点，提出的配置发现。
