Abstract
The effects of two kinds of coherent lengths, the wavepacket length of the emitter and the radius of the coherent source, on the pion spectr um distribution are studied. It is shown that both coherent lengths ca n cause abundant pions at low momentum, but the disoriented chiral con densate (DCC) size effects on the pion spectrum distribution are more important. Therefore, observing abundant pions at low momentum may be taken as a signal of DCC effects.
