What does Z represent in physics?

Z particle, massive electrically neutral carrier particle of the weak force that acts upon all known subatomic particles. It is the neutral partner of the electrically charged W particle.

Is Za a field?

The integers are therefore a commutative ring. Axiom (10) is not satisfied, however: the non-zero element 2 of Z has no multiplicative inverse in Z. That is, there is no integer m such that 2 · m = 1. So Z is not a field.
