TL;DR: Weak interactions of leptons and quarks have been studied extensively in the literature as mentioned in this paper, with a clear presentation of the modern theoretical basis of weak interactions, going on to discuss recent advances in the field.
Abstract: In recent years, the study of weak interaction and its relationship with the other fundamental interactions of nature has progressed rapidly. Weak interactions of leptons and quarks provides an up-to-date account of this continuing research. The Introduction discusses early models and historical developments in the understanding of the weak force. The authors then give a clear presentation of the modern theoretical basis of weak interactions, going on to discuss recent advances in the field. These include the development of the electroweak gauge theory and the discovery of neutral currents and of a host of new particles-notable among these are the /tau/ lepton and the charmed quark. There is also a chapter devoted entirely to neutrino astrophysics.

TL;DR: In this paper, the masses of most of the new, unobserved particles in unified gauge theories were found by requiring that the partial-wave amplitudes satisfy unitarity bounds, where the amplitudes of a particle are independent of its mass.
Abstract: Upper bounds are found for the masses of most of the new, unobserved particles in unified gauge theories by requiring that the partial-wave amplitudes satisfy unitarity bounds.

TL;DR: In this article, the renormalization of the unified theory of weak and electromagnetic interactions due to Salam and Weinberg is studied, in which the infinities can be absorbed by defining bare and renormalized Lagrangians, which have the same structure and the same number of independent parameters.
