Under this assumption, the problematic $t$-channel pole is canceled with the UV integral of the imaginary part of the amplitude in the dispersion relation, which gives rise to finite corrections to the positivity bounds. We find that low-energy effective field theories (EFT) with \"wrong\" sign are generically allowed. The allowed amount of the positivity violation is determined by the Regge behavior.
