New technique for determining the properties of a narrow s-channel resonance at a muon collider

We explore an alternative to the usual procedure of scanning for determinin g the properties of a narrow s-channel resonance. By varying the beam energ y resolution while sitting on the resonance peak, the width and branching r atios of the resonance can be determined. The statistical accuracy achieved is superior to that of the usual scan procedure in the case of a light sta ndard-model-like Higgs boson with M-H > 130 GeV or for the lightest pseudog oldstone boson of a strong electroweak breaking model if M-P0 > 150 GeV.
