The observability of a charged Higgs boson produced in association with a W boson at future muon colliders is studied. The analysis is performed within the MSSM framework. The charged Higgs is assumed to decay to and a fully hadronic final state is analyzed, i.e., . The main background is production in a fully hadronic final state which is an irreducible background with very similar kinematic features. It is shown that although the discovery potential is almost the same for a charged Higgs mass in the range , the signal significance is about 1σ for tanβ=50 at integrated luminosity of 50 fb−1. The signal rate is well above that at e + e − linear colliders with the same center of mass energy, and enough data (O(1 ab−1)) will provide the same discovery potential for all heavy charged Higgs masses up to ; however, the muon collider cannot add anything to the LHC findings.
