Abstract
The knowledge of the radiative corrections to the energy spectrum of particles produced in the semileptonic decay of hyperons is fundamental for a precise determination of the parameters that as well contain information about the basic structure of particles constituted by quarks. From the analytical formulas for the bidimensional distribution of energies, expressed in terms of the energies of the hadron and lepton (electron) produced in the decay, the precise and very accurate β energy spectrum is obtained for unpolarized hyperons semileptonic decays of charged and neutral baryons. This result unlike the one for the energy distributions does not contain any logarithmic divergences and is directly evaluable for any physically possible event.
