Description

We analyse the semileptonic decay of the $D_s$ meson, focusing on the $D_s\to X\ell \nu$ channel based on Extended Twisted mass ensembles at the physical pion mass value.
On the basis of four-point correlation functions, we use the HLT reconstruction method to calculate the differential decay rate, allowing us to analyse the inclusive decay.
The analysis is performed at four different lattice spacings, and three different volumes to address the associated systematic uncertainties.
