Conservation laws: Is the decay Σ⁺ → p + π⁺allowed? A) Yes, because it conserves energy. B) No, because charge is not conserved. C) No, because mass is created. D) No, because lepton number is not conserved.

Charge is not conserved in this decay because the initial state has a total charge of +1 (ΣS1U1P1) while the final state has a total charge of 0 (p + πS1U1P1 + S1S1P0S1U1B1 + S1U1B0). Therefore, the decay violates conservation of charge and is not allowed.
