- Below Eq. (3.16), the energy \(E_i\) of the \(i\)th particle is defined by \(E_i^2 = |\textbf{k}_i|^2 + m_i^2\).
- The left-hand side of Eq. (3.26) is \(A^{(1)}(s_1,\cdots,s_r)\).
- In Eq. (1.98), the sign of \(\text{i} \ p^2\) has to be flipped in the expression of both \(\lambda^{\alpha}\) and \(\tilde{\lambda}^{\dot{\alpha}}\).
