2) Kaons are the lightest mesons that contain at least one strange or anti-strange valence quark. The positive kaon (K+) has the valence quark content us and it can be produced in the reaction T+ p → K+ +¯ + A, which proceeds through the strong interaction. (a) Draw a quark flow diagram for the reaction 1¯ +p→ K+ +¯ + A and deduce the valence quark content of A. b) A negative pion with energy E is incident on a stationary proton p. Show that the minimum pion energy Emin required for the reaction T +p→ K+ + T+A to occur is (тк + т, + mл)? — т? — т? Emin 2mp where mr, mp, mK, and ma are the a, p, K+ and A masses, respectively.
