The Excess of HERA High$-Q^2$ Events and Leptoquarks in a Left-Right Symmetric Preon Model

An interpretation that the HERA excess events are due to intermediate production and decay of composite leptoquarks in the left-right symmetric preon model is given. Because of the preon-line rule, expected to be valid well, the event-ratio of neutral to charged current interactions is predicted to be one.
