WebOn the other hand, an up-antistrange pair (like a kaon) can't decay through the strong interaction, so it needs to go through the weak interaction. The antistrange quark emits a W boson while becoming an antidown quark. Similarly, light quark-antiquark pairs like the pions can decay weakly by becoming W bosons which then decay into leptons.

WebJul 29, 2024 · A tetraquark composed of two charm quarks and an up and a down antiquark (Image: D. Dominguez/CERN) Quarks are the fundamental building blocks from which matter is constructed. They combine to form hadrons, namely baryons, such as the proton and the neutron, which consist of three quarks, and mesons, which are formed as quark-antiquark … WebBranching ratio to quark-antiquark pairs: (69.90+/- 0.15)% Do your numbers agree? If not, can you guess why? The reason is the particles called neutrinos that escape the detector unseen. These account for about 20% of all Z particle decays, that's why if you add up the branching ratios to visible particles (listed above), you only get 80%.
