In particle physics, a spinor field of order 
describes a particle of spin 
,
where 
is an integer or half-integer. Therefore, a spinor of
order 
contains as much information as a tensor of order 
. As a result of this, particles of integer spin (bosons)
can be described equally well by tensor fields or spinor fields, whereas particles
of half-integer spin (fermions) can be described only by spinor fields. Spinor fields
describing particles of zero rest mass satisfy the zero
rest mass equation.
