For ten points, identify these objects first proposed by Wolfgang Pauli to explain energy loss in beta decay.
They are the subject of John Updike's poem, "Cosmic Gall," in which he berates them as "crass" for passing nonchalantly through everything on Earth. Actually, physicists are concerned because it seems that not as many pass through their detectors as expected. It may be that the sun's  core is cooler than we think, or it may be that these particles have some rest mass and oscillate between electron, muon, and tau varieties.
