For example, the following formula for vertex operators is often cited $:e^{i\alpha_1\phi(z_1,\bar{z}_1)}::e^{i\alpha_2\phi(z_2,\bar{z}_2)}:=:e^{i\alpha_1\phi(z_1,\bar{z}_1)}e^{i\alpha_2\phi(z_2,\bar{z}_2)}:e^{-\alpha_1\alpha_2\langle\phi(z_1,\bar{z}_1)\phi(z_2,\bar{z}_2)\rangle}$. With your prescription correlator of any number of vertex correlators would be zero, independent of the neutrality condition. | |
