Requirements for calorimetric jet mass reconstruction for high p sub perpendicular jets at the SSC

We have studied two aspects of calorimetry for high p{sub {perpendicular}} jets at the SSC. First, the impact of shower containment on very high p{sub {perpendicular}} jets and quark compositeness has been studied. Second, the effect of calorimeter granularity on the mass reconstruction of a high p{sub {perpendicular}} W (p{sub {perpendicular}} > 500 GeV/c) producing jets has been examined in detail. We conclude, based on possible compositeness signatures only, that shower leakage has little effect on the compositeness signal for a calorimeter thickness greater than about eight absorption lengths. Mass resolution of very high p{sub {perpendicular}} W's reconstructed from hadronic decays of the W is strongly affected by intrinsic shower spreading as well as calorimeter granularity. These effects are quantified. 20 refs., 17 figs., 2 tabs.
