Guang Yang - Invisible scattering

• EC: For the systematics on the reconstruction the error is very high at low energy, probably we will not be able to measure the cross-section below 100 MeV.
• MD: At the moment the invisible scattering understanding only on the MC. I'd investigate it changing the threshold.
• GY: We don't have a reliable simulation of the MPPC. MD: We can extrapolate it from data.
• MD: It is possible to reduce the threshold for the part of the detector for which the MPPC is less noise and see how the data and MC comparisons change.
