Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the gauge boson family?They are fundamental gauge bosons mediating the weak nuclear force
2. What is the electroweak unification?Integral to the electroweak theory, unifying electromagnetic and weak forces
3. Why are W and Z bosons important for stars?They help protons fuse into deuterium in the Sun, turning hydrogen into helium and releasing energy that lights stars.
4. How were W and Z bosons discovered?In 1983 at CERN, scientists smashed protons and antiprotons together in a huge machine, and the experiments UA1 and UA2 saw the particles appear and then disappear quickly.

Gauge Boson: A fundamental particle that mediates a force, like the photon or W/Z bosons.
Electroweak Theory: A theory unifying the electromagnetic and weak nuclear forces.
Standard Model: The current theoretical framework describing fundamental particles and their interactions.
