Identify the gauge bosons responsible for the electromagnetic, weak, and strong forces.

Answer explanation

1. The gauge bosons responsible for the electromagnetic force, weak force, and strong force are photon, W and Z bosons, and gluons, respectively.

Name the particle associated with the Higgs field.

Answer explanation

Higgs Boson

Which particle is its own antiparticle?

Answer explanation

neutrino. However, it is important to note that neutrinos are electrically neutral and do not have distinct antiparticles like other charged particles.

Which particle carries a fractional electric charge?

Answer explanation

Quarks have fractional charges of either +2/3 or -1/3.

Identify the three generations of matter particles in the standard model.

Answer explanation
