Query: Evidence for a long duration component in the prompt emission of short
  Gamma-Ray Bursts detected with BeppoSAX   A statistical study on the light curves of all the short Gamma-Ray Bursts
detected with the Gamma Ray Burst Monitor (GRBM) aboard BeppoSAX is reported.
Evidence for a very weak and long duration component associated with these
events in the two 1 s counters of the GRBM (40-700 keV and >100 keV) is found.
It starts a few tens of seconds before the burst and continues for about 30 s
after the burst. The overall hardness of this component is comparable with that
of the event itself. The detection of a signal before the onset time and the
similar hardness are consistent with an interpretation of the long duration
component in terms of prompt emission associated with short GRBs.
