Rho to pi gamma

  1. Jun 19, 2015 #1
    1. The problem statement, all variables and given/known data
    Show Γ(ρ0→π0γ) = Γ(ρ+→π+γ)
    Using G- and isospin symmetries, without exact calculating the matrix elements using additive quark model.

    2. Relevant equations
    L = jμAμ
    G = CR1802
    Mif ≅ <π|jμ|ρ>eμ
    jμ=2/3 * (anti u)γμu - 1/3 * (andi d)γμd)

    3. The attempt at a solution
    Mif ≅ <π|G-1GjμG-1G|ρ>eμ
    jμ = jμS + jμA
    GjμG-1 = jμS - jμA
