The presentation proceeds in two parts. We first consider Standard Model predictions, taking into account both short-distance and long distance effects. Then several New Physics options (e.g. supersymmatry, strong dynamics, extra large dimenions, etc) are considered.8 pages, 5 figures, talk delivered at Electroweak Moriond 2002High Energy Physics - Phenomenologytext
