Item Description:The theoretical understanding of elementary particle interactions has undergone a revolutionary change during the past one and a half decades. The spontaneously broken gauge theories, which in the 1970s emerged as a prime candidate for the description of electro-weak (as well as strong) interactions, have been confirmed by the discovery of neutral weak currents as well as the w- and Z-bosons. We now have a field theory of electro-weak interactions at energy scales below 100 GeV- the Glashow-Weinberg-Salam theory. It is a renormalizable theory which enables us to do calculations without encountering unnecessary divergences. The burning question now is: What lies ahead at the next level of unification? As we head into the era of supercolliders and ultrahigh energy machines to answer this question, many appealing possibilities exist: left-right symmetry, technicolor, compositeness, grand unification, supersymmetry, supergravity, Kaluza-Klein models, and most recently superstrings that even unify gravity along with other interactions. Experiments will decide if any one or any combination of these is to be relevant in the description of physics at the higher energies. As an outcome of our confidence in the possible scenerios for elementary particle physics, we have seen our understanding of the early uni verse improve significantly
