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.
