Recent simulations of cold dark matter distributions in galaxies call for self-interacting, non-pointlike dark matter. Extended objects arise in many theories that are regarded as candidates for physics beyond the standard model. For example, Q-balls appear in the spectrum of every supersymmetric extension of the standard model. Q-balls can form in the early universe and can exist as a form of dark matter. If the non-pointlike dark matter is detected in WIMP searches, one can distinguish the signal from that of pointlike particles.
