We are working mainly on strange things, which sound maybe odd but it refers simply to particles containing a strange quark. Why is the study of mesons and baryons with a strange content relevant for the human kind? One of the pioneering idea behind this study was the hypothesis that neutron stars might have a condensate of strange particles in their core. Astronomers looks at neutron stars and determine their mass and radii, we collide nuclei in the laboratory and try to produce high density environments, to measure there strange particles and help theoreticians in constraining models for neutron stars... among other things.
