In this work, the lightcone bootstrap was applied to study the four-point function of scalars in two-dimensional conformal field theory, including the entire Virasoro symmetry. A kernel ansatz was proposed to generalize the spectral decomposition of the Virasoro vacuum, extending it beyond the large dimension limit.
In this work we apply the lightcone bootstrap to a four-point function of scalars in two-dimensional conformal field theory. We include the entire Virasoro symmetry and consider non-rational theories with a gap in the spectrum from the vacuum and no conserved currents. For those theories, we compute the large dimension limit (h/c >> 1) of the OPE spectral decomposition of the Virasoro vacuum. We then propose a kernel ansatz that generalizes the spectral decomposition beyond h/c >> 1. Finally, we estimate the corrections to the OPE spectral densities from the inclusion of the lightest operator in the spectrum.
