\section{Gauge Group}

The Standard Model gauge group is

$$
SU(3)_C\times SU(2)_L\times U(1)_Y.
$$

It organizes the strong, weak, and electromagnetic interactions.

\section{Matter Content}

Matter fields are quarks and leptons. Quarks carry color charge and participate
in the strong interaction. Leptons do not carry color charge.

\section{Force Carriers}

Gauge bosons mediate interactions: gluons for QCD, $W^\pm$ and $Z$ for the
weak interaction, and the photon for electromagnetism.
