Conservation Laws: State whether the following reactions are allowed or forbidden. If they are forbidden, state the reason(s). The quark contents of the charmed particles involved in the reaction are: the charmed hyperon A, is udc, the D+ meson is cd and the D- meson is ēd. Similarly, the beauty mesons below have quark content A, (udb) and B+ (ub). (i) + +P→ D¯ + Ac+nº (ii) +p B+ + A + ¯ (iii) K+p→K+ + E + (iv) + +pD++ A+ A+
