The production of heavy particles at hadron colliders is associated with radiation of additional quarks and gluons from incoming partons. They can have significant transverse momenta and the additional initial state radiation (ISR) jets complicate the reconstruction of new particle masses. Taking gluino pair production and decay at the Large Hadron Collider as an example, we develop a novel technique to reduce these effects, allowing for a better reconstruction of masses through the measurement of kinematical end points.
