Question

What is the 1/2 spin analog of the graviton called?

Answer 1

In some supergravities you have the gravition, gravitino, graviphoton and graviscalar. Each is analogous to each other in only sharing gravitational properties and nothing else. They differ by spin in the order of 2, 3/2, 1 and 0. What is the spin 1/2 analogue named.

Answer 2

In quantum mechanics, spin is an intrinsic property of all elementary particles. Fermions, the particles that constitute ordinary matter, have half-integer spin ...
