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 particle type?Third-generation charged lepton
2. What is the discoverer?Martin Perl and the SLAC-LBL Mark I collaboration
3. What is a tau particle?A tau is a tiny, fast-moving particle that is a cousin of the electron but much heavier. It is one of the three types of charged leptons in the Standard Model.
4. How heavy is a tau compared to an electron?A tau is about 3,500 times heavier than an electron and about 17 times heavier than a muon.

Charged Lepton: A fundamental particle with electric charge and spin 1/2, belonging to the lepton family.
Branching Ratio: The probability that a particle will decay into a specific set of other particles.
Neutrino Oscillation: The quantum mechanical phenomenon where a neutrino changes its flavor (electron, muon, or tau) as it travels.
