The TASSO collaboration refers to the group of people working on the TASSO detector, at PETRA, at DESY. They are famous for having discovered the gluon, the mediator of the strong interaction and carrier of the color charge. Four of them, Paul Söding, Bjørn Wiik, Günter Wolf, and Sau Lan Wu, were award the Prize for High Energy and Particle Physics from CERN in 1995. A special prize was also awarded to the TASSO collaboration, as well as the PETRA, JADE, MARK J, and PLUTO collaborations, in recognition of their combined work on the gluon as the "definite existence (of the gluon) emerged gradually from the results of the TASSO collaboration and the other experiments working at PETRA, JADE, MARK J and PLUTO".
