C in the Short-Time Approximation

The Short-time approximation has been developed in the context of quantum Monte Carlo calculations to calculate nuclear responses in nuclei with A≥12. This algorithm exploits a factorization scheme to consistently retain two-body physics, both in two-body currents and correlations.

In this talk, we will present developments in the calculations of response densities in ¹²C, as well as recent results for longitudinal and transverse electromagnetic response functions.

We will also discuss the removal of the elastic contribution from the response densities calculated in the STA, necessary to reproduce experimental data for exchange momenta down to q=300 MeV.
