  One of the main physics goals of the Large Hadron Collider is the search of
particles predicted by supersymmetric theories. This study analyses the
possibility of using kinematic endpoints of mass spectra for a sparticle mass
reconstruction. It focuses on cascade decays, which include the second-lightest
neutralino, in the mSUGRA framework with tan(b) = 35, A0 = 0 and positive mu. A
region of 25 points around the benchmark point I' with m0 = 181 and m1/2 = 350
is chosen, where the cascade decay of the second-lightest neutralino into two
opposite-sign taus and the lightest neutralino has a branching ratio of over
95%. Two methods of measuring 13 kinematic limits are tested systematically at
Monte Carlo generator level.
