The Standard Model includes 3 gauge bosons of spin 1, with bosons being quantum particles containing an integer spin.
The gauge bosons are defined as force carriers and consist of the photon, W and Z bosons, gluon, mediating the electromagnetic, weak, and strong fundamental interactions.
In other words, the Standard Model is not only a list of ingredients but it describes the relationships between those ingredients.
Together, they account for all the matter physicists have observed, including fleeting bits of matter that require high-end detectors in particle accelerators.
The Standard Model explains three of the four fundamental forces that govern the universe: electromagnetism, the strong force, and the weak force.
Electromagnetism is carried by photons and involves the interaction of electric fields and magnetic fields.
