欧洲核子研究中心最近公布了质量为115 GeV的希格斯玻色子的LEP实验证据。第一台介子对撞机将是研究这种希格斯玻色子的最佳加速器。直接产生希格斯粒子的横截面要比产生Z粒子的横截面大得多，这对μ子对撞机来说是一个优势。储存环的周长为350米，光度为2/ spl × / 10/sup 31/ cm/sup 2/ s/sup -1/，能量分布为0.0001 [/spl Delta/ E/E]。将介子储存环作为中微子工厂进行可行性研究。此外，还对高亮度μ子对撞机纵向冷却所需的发射度交换进行了进一步的研究。利用这些研发成果，一项开发μ子对撞机希格斯工厂的新研究正在进行中。本文将介绍本研究的现状。
Evidence from the LEP experiments for a Higgs boson at a mass of 115 GeV has recently been presented at CERN. The first muon collider would be the best accelerator at which to study such a Higgs boson. The cross section for direct Higgs production is much larger than the associated production with a Z, which is an advantage for the muon collider. The storage ring would be 350 meters in circumference with a luminosity of 2 /spl times/ 10/sup 31/ cm/sup 2/ s/sup -1/ and an energy spread of 0.0001 [/spl Delta/ E/E]. Feasibility studies for muon storage rings as neutrino factories have been undertaken. In addition, further R&D has been done on emittance exchange needed for longitudinal cooling at a high luminosity muon collider. Using the results of these R&D efforts, a new study to develop a muon collider Higgs factory is underway. The current status of this study will be presented.
