A model of binary collisions dependence of jet quenching in nuclear collisions at ultrarelativistic energies

We describe a model of jet quenching in nuclear collisions at RHIC energies. In the model, jet quenching is to be caused by the interruption of jet formation by nucleons arriving at the position of jet formation in a time shorter than the jet formation time. Our mechanism predicts suppression of high-pt spectra also in d+Au reactions.
