Higgs Measurements at a Muon Collider

Understand

In light of the recent discovery of an approximately 126 GeV Higgs boson at the LHC, the particle physics community is beginning to explore the possibilities for a next-generation Higgs factory particle accelerator.

• In this report we study the s-channel resonant Higgs boson production and Standard Model backgrounds at a proposed \mu+\mu- collider Higgs factory operating at center-of-mass energy sqrt(s) = M_H with a beam width of 4.2 MeV.
• We study PYTHIA-generated Standard Model Higgs and background events at the generator level to identify and evaluate important channels for discovery and measurement of the Higgs mass, width, and branching ratios.
• We find that the H^0 -> bb and H^0 -> WW^* channels are the most useful for locating the Higgs peak.
