A Browser for Deep Inelastic Scattering Kinematics. The kinematics of a DIS event is not necessarily intuitive for non-experts. What is the scattering angle of the lepton and what is its energy for a given x and Q2? Or, what is x and y for a given angle and energy of the scattered quark? What is the range of energies and angles for the kinematic region I am interested in? If you are in need for a simple way of finding answers to these questions, look no further. eDISK is for you. It not only calculates all relevant variables interactively but also visualizes the event for you. This documentation will help you to not only use eDISK but also will provide some insight into the meaning of the various variables and how they are calculated.
