Popis:	Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2019, Tutor: Joan Soto We fit lattice QCD results of baryon-baryon potentials in the strangeness S= -4 sector using the Effective Field Theory (EFT) and show how good this fit is. Next, we estimate some physical parameters associated to this interaction. These parameters include scattering length and the Ξ axial coupling constant (𝑔A). Finally, we compare our results to One Boson Exchange models
