The mathematical language of the Standard Model is called Quantum Field Theory, in particular a class of theories called Nonabelian Gauge Theories, which are generalizations of QED
The usual physicist’s abbreviation for the standard model looks like
SU(3) ! SU(2) ! U(1)
These symbols are names for certain mathematical objects called groups. Roughly speaking, the group U(1) is associated with QED, the group SU(2) is associated with the Weak force, and SU(3) is associated with the Strong force.
