Abstract: We describe a method for interpreting trilepton searches at high energycolliders in a model-independent fashion and apply it to the recent searches atthe Tevatron. The key step is to recognize that the trilepton signature iscomprised of four experimentally very different channels defined by the numberof tau-leptons in the trilepton state. Contributions from these multiplechannels to the overall experimental sensitivity cross section times branchingratio are model-independent and can be parametrized in terms of relevant newparticle masses. Given the trileptonic branching ratios of a specific model,these experimentally obtained multichannel sensitivities can be combined toobtain a cross section measurement that can be used to confront the model withdata. Our model-independent results are more widely applicable than the currentTevatron trilepton results which are stated exclusively in terms of mSUGRAparameters of supersymmetry. The technique presented here can be expandedbeyond trilepton searches to the more general -inverse problem- ofexperimentally discriminating between competing models that seek to explain newphysics discovered in multiple channels.
