It has long been known that intersection theory on the moduli space of punctured Riemann surfaces computes all observables in the two-dimensional quantum gravity. It is natural to ask whether interacting theories could also admit a similar description. In the genus-zero case we construct a twisted version of intersection theory on the moduli space and propose that it gives rise to tree-level scattering amplitudes in a range of quantum field theories. We present recursion relations for intersection numbers on the natural fibration of moduli spaces.
