The decay of hyperons proceeds via the weak transition of a strange quark into an up quark. The strength of this transition is governed by the Cabibbo angle, a fundamental parameter of the Standard Model. Determining this parameter through different processes provides an important test of the model’s consistency. In this work, we study the four-body decay of the Σ⁺ hyperon, Σ⁺ → 𝑝𝜋⁺𝑒⁻𝜈_𝑒 , as a prime example of a channel that produce charged final-state particles. The presence of charged particles such as the proton and pion makes this decay mode experimentally more accessible, as they can be efficiently tracked and identified in modern detectors. This stands in contrast to the corresponding three-body decay, Σ⁻→ 𝑛𝑒⁻𝜈_𝑒 , where the neutron in the final state is neutral and therefore more difficult to detect directly. We compute the decay width and analyze the kinematics of this process to evaluate its observability. This channel offers a complementary probe of weak interactions in the baryon sector and may provide an alternative means to extract the Cabibbo angle
