Manuel González López will present Weak Interactions with Lepton-Hadron Symmetry (S.L. Glashow, J. Iliopoulos, L. Maiani) publicado en Phys.Rev.D 2 (1970) 1285-1292. 

We propose a model of weak interactions in which the currents are constructed out of four basic quark fields and interact with a charged massive vector boson. We show, to all orders in perturbation theory, that the leading divergences do not violate any strong-interaction symmetry and the next to the leading divergences respect all observed weak-interaction selection rules. The model features a remarkable symmetry between leptons and quarks. The extension of our model to a complete Yang-Mills theory is discussed.
