Draw quark-flow feynman diagram for the reaction

Reference no: EM13536878

One of the strange particles observed in early bubble chamber experiments was Ξ, called the “cascade” particle. It was produced in the reaction,

Κ- + p → Κ⁺ + Ξ- …………………(1)

and it decayed through the cascade Ξ- → Λ + π- (2) followed by Λ → P + π- (3) .

(a) Draw quark-flow Feynman diagram for the reaction (1).

The quark configurations are Κ⁺(u sbar), Κ- (us), Ξ- (dss).

(b) Draw Feynman diagrams at quark level for the decays (2) and (3).

The quark configuration of Λ is uds.
