In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

The spin of these particles was confirmed experimentally by determining the distribution of the EllisKarliner angle. SCET provides a framework for doing calculations when these particles are at low energies or moving in the same direction as particles they interact with. The clearest evidence of these particles' existence came from the decay of a quark resonance into three jet events at DESY's PLUTO experiment, and they are depicted using a spiral in Feynman diagrams. These bosons and quarks form a namesake plasma or "soup," and are responsible for an interaction approximately 39 magnitudes more effective than gravity. For 10 points, identify these gauge bosons which help hold atomic nuclei together by mediating the strong force.
