Question

The study of this class of particles motivates C·A·R algebras, which complement CCR algebras. The Hubbard model features (20[1])a lattice of this class of particles. The antisymmetric (20[1])wave functions (20[1])of these particles (20[4])cause them to be described (20[1])by (20[1])anti-commuting fields (20[1])in the spin–statistics theorem. Examples of these (20[1])particles that behave as their own antiparticles were hypothesized (20[1])by Ettore Majorana. (20[2])Baryons (20[2])(*) exemplify the “composite” type of these particles whose “elementary” (10[1])type is exemplified by quarks and leptons. (10[1])The (10[1])Pauli exclusion principle applies (10[2])to these particles, (10[1])which have half-integer spin. (10[1])For 10 points, (10[1])name these particles that are contrasted with bosons (10[1])and named for an Italian physicist. (10[3])■END■ (10[6])
