The exact formulation of the guage models unifying the Weak and the Electromagnetic Interactions or the Lagrangian Field Theory of the Strong Interactions, called Quantum Chromodynamics is dependent on experimental findings. We put forward a model for the Weak Interactions to fit all available experimental data after considering a class of proposed models. A new parameter is added to the standard Weinberg-Salam model in order to give the best fit with the experimental data, and several tests for determining this parameter accurately are proposed. A detailed discussion of various future experimental tests and comparisons that can be made with the other existing models are also considered. These include the asymptotic ratio of antineutrino to neutrino deep-inelastic scattering, elastic scattering from protons, direct decays of charmed mesons into neutral leptonic channels, effects in atomic physics, and coherent neutrino-nucleus scattering. It is shown that although the neutral current experiments are the hardest to perform, this aspect of the Weak Interactions gives the best checks and is one of the better ways to sift through the multitude of models.
