The spin-2 polarization sum in d dimensions is given by [44, 58]: $$\begin{aligned} B^{\mu \nu ;\rho \sigma }(q)= & {} \bigg ( g^{\mu \rho } - \frac{q^{\mu }q^{\sigma } }{q.q} \bigg ) \bigg ( g^{\nu \sigma } - \frac{q^{\nu }q^{\sigma } }{q.q...
A popular tool in this regard has been to employ unitarized versions of ChPT, such as the inverse amplitude method (IAM) [6,7,8,9]: a resummation of higher-order effects obeying S-matrix unitarity (i.e., probability conservation) allows one to generate poles on unphysical Riemann sheets...
