All but four of these objects are pseudoscalars, meaning that they change sign under a parity transformation.
All but four of these objects are pseudoscalars, meaning that they change sign under a parity transformation. There are only two of these objects that are made up of three different types of constituent particles, and the most famous of these objects was discovered as the mediator of an eponymous potential that scales as quantity e to the minus r over r. Another form of these objects provided the solution to the tau-theta puzzle and was the particle in which Cronin and Fitch discovered CP violation. More famously, the discovery of charmonium, more commonly known as J/psi one, provided experimental confirmation of the Eightfold Way. FTP identify these hadronic particles which, unlike baryons, consist of quark-antiquark pairs.
