It mediates the quantum field of the same name, which has a constant vacuum expectation value of 246 gigaelectronvolts. It is CP-even, but because it is a scalar particle, it has zero spin. Several alternate models, such as top quark condensate theory, have been proposed in which it need not (*) exist, as it is the only particle in the Standard Model that has yet to be observed.
