For example, the tau lepton is roughly 3600 times more massive than the electron, and the top quark is nearly 100,000 times heavier than the up quark. That difference manifests itself in stability: ...
The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally change into one another. The amounts in which these processes happen are not ...
The top quark is the sixth, and quite possibly the last, quark. ... It requires that leptons and quarks each come in pairs, often called generations. On supporting science journalism.
we can determine how many generations of particles there are. As it turns out, 1-out-of-30 Z-bosons decay to each of electron/positron, muon/anti-muon, and tau/anti-tau pairs, while a total out of ...
There are three generations of quarks varying in mass, with charm quarks being part of the second generation of quarks. The dead cone effect tells physicists why heavy quarks from the second and ...
