The Hyperon Beam Experiment WA89 is a large acceptance forward spectrometer
dedicated to the spectroscopy of charmed strange baryons and exotic multiquark
states like the U-diquonium and the H-dibaryon. The strange quark in the beam
should make a production of final states containing strangeness rather
efficient. The study of charmed baryons aims at the better understanding of
charm and baryon production and their decay properties governed by an interplay
of weak and strong interaction. The observation of yet unobserved missing
baryon ground and excited states will be a further test of the very successful
constituent quark model. This is true in particular for the spectroscopy of
exotic quark configurations as their observation or nonobservation will lead to
a deeper understanding of the short range interaction between quarks bound in a
