In statistical mechanics, the expected number of t
In statistical mechanics, the expected number of these particles in a given state is inverselyproportional to an exponential weight minus one. Composite particles that belong to this general class arethe basis for the BCS theory of superconductivity. These particles leave the sign of the wavefunctionunchanged upon particle exchange and include (*) Cooper pairs. They do not obey the Pauli exclusionprinciple because they obey a set of statistics named for their namesake and Einstein. Photons are an example of the"gauge" type of these particles that have integer spin. For 10 points, name this particle whose Higgs type wasdiscovered at the Large Hadron Collider.
