T*-PRODUCT AND FALSE NONCONSERVATION OF ANGULAR MOMENTUM IN THE PION DECAY

In the framework of the intermediate vector boson theory, developed in the early 1960s, T*-product induces false nonconservation of angular momentum in the π→μ+ν decay. It points out that if correctly formulated, the pion cannot decay and clarifies how this problem can be resolved in the electroweak theory. In this consideration, some unexpected facts are found.

PROPERTIES OF THE W BOSON FROM THE FERMILAB TEVATRON

The experimental knowledge of the charged intermediate vector boson, the W, is reviewed. Measurements of the electroweak properties of the W boson, such as its mass, decay width, couplings to fermions, and leptonic branching ratios, are summarized. As well, I review production properties of the W as measured in [Formula: see text] collisions and how they can be used as tests of perturbative QCD. I also discuss new particle searches that make use of the W signature, such as new charged electroweak bosons and the now-confirmed discovery of the top quark.
