The saxion is the scalar superpartner of the
axion, and part of a
chiral superfield
In theoretical physics, a supermultiplet is a representation of a supersymmetry algebra.
Then a superfield is a field on superspace which is valued in such a representation. Naïvely, or when considering flat superspace, a superfield can simply ...
. The axion represents the CP violating theory of the Standard Model. The axion and saxion are examples of the
scalar boson class of particles with a very small mass, and a charge of 0.
