The four-jet final state is analyzed to search for hadronic decays of pair-produced heavy particles.The analysis uses the ALEPH data collected at LEP in November 1995 at centre-of-mass energies of 130 and 136 GeV. An excess of four-jet events is observed with respect to the standard model predictions. In addition,these events exhibit an enhancement in the sum of the two di-jet masses around 105 GeV. The properties of these events are studied and compared to the expectations from standard processes and to pair production hypotheses..

Particle physics and astrophysics have developed close ties over the last three decades, largely motivated by a deeper understanding of the early development of the universe. In recent years the ties have grown to include the experimental sector, and the cooperation is growing rapidly. These activities are now known as `particle astrophysics'. In this seminar, after a survey of the particle astrophysics agenda, it is suggested that CERN should widen its experimental horizon to include particle astrophysics experiments - which are already foreseen within the CERN Convention..
