Abstract:
General calculations concerning the kinematics of massive unobserved particles in the final state are discussed. We then apply these calculations to a method that allows one to determine the spin of such particles that escape direct detection. From this context, an analysis of the ability of a lepton collider to determine the spin of a dark matter candidate, such as a weakly interacting massive particle (WIMP), using this method is provided. Our discussion is model independent, and is derived purely from kinematical considerations.
