abstract
We studied the feasibility of the measurement of Higgs pair creation at a photon linear collider. From the sensitivity to the anomalous self-coupling of the Higgs boson, the optimum γγ collision energy was found to be around 270 GeV for a Higgs mass of 120  GeV/c2. We found that large backgrounds such as γγ→W+W-, ZZ, and bb̅ bb̅ can be suppressed if correct assignment of tracks to parent partons is achieved and Higgs pair events can be observed with a statistical significance of ∼5σ by operating the photon linear collider for 5 years.
