Line 97: − === Proton-Reggeon vertex ===+ − − The amplitude for the emission of the exchange particle (Reggeon) at the baryon vertex can be described as the decay of the target proton into the final-state baryon plus the exchange particle. Following the prescription developed above, this amplitude is written as − − :<math> − \langle \Omega_R ; J_R \lambda_R \epsilon_R; J_P \lambda_p | W | J_T m_T \rangle − = − \langle \Omega_R ; J_R \lambda_R \; \mp\epsilon; \textstyle{\frac{1}{2}}\;\lambda_p − | \textstyle{\frac{1}{2}}\;m_T \lambda_R \lambda_p \rangle \langle \textstyle{\frac{1}{2}}\;m_T \lambda_R \lambda_p | − W | \textstyle{\frac{1}{2}}\;m_T \rangle − </math></td> − <td> − transition amplitude for <math>p \rightarrow R + p'</math> − in the direction <math>\Omega_R</math> w.r.t. the coordinate − system defined in the resonance RF. − </td> − </tr> − <tr> − <td><math> − =\frac{1}{\sqrt{2\pi}} \left[ − D_{m_T (\lambda_R-\lambda_p)}^{\frac{1}{2} *} (\Omega_R,0) \; w_{\lambda_R\; \lambda_p} − \mp − \epsilon P_R (-1)^{J_R-\lambda_R} − D_{m_T (-\lambda_R-\lambda_p)}^{\frac{1}{2} *} (\Omega_R,0) \; w_{\lambda_R\; -\lambda_p} − \right] − </math></td> − <td> − follows from relations given above − </td> − </tr> − </table> − − === Decay ===
