Abstract
Spike production is studied in pp and π+p/K+p collisions in the beam-momentum range of 205-360 GeV/c. The pseudorapidity distribution of spike centers exhibits two narrow peaks in pp interactions, while having one wide bump in πC and Kp interactions. The position of the peaks is consistent with the expectation from a model of coherent gluon radiation at finite length. The interference between the quark color amplitudes obtained within this model causes two off-center peaks in pp data, but only one central peak in πP and Kp data.
