Description
The instability of hyperons against the weak interaction hampers the direct extraction of baryon-baryon low-energy observables from experiments. In this energy region, a reliable numerical procedure to obtain information of nuclear physics quantities in the strange sector is the Lüscher’s method. Working in a discretized Euclidean space-time, the approach relates the modifications on the energy levels of two-particles placed in a finite volume (due to their mutual interactions), extracted via Lattice QCD, with relevant physical observables in the low-energy regime.
In this contribution, I would like to illustrate the robustness of our method by presenting the results obtained at $m_{\pi}\sim$ 450 MeV with different analysis.
