Constraints on the phase and new physics from Decays
Recent results from CLEO on indicate that the phase may
be substantially different from that obtained from other fit to the KM matrix
elements in the Standard Model. We show that extracted using is sensitive to new physics occurring at loop level. It provides
a powerful method to probe new physics in electroweak penguin interactions.
Using effects due to anomalous gauge couplings as an example, we show that
within the allowed ranges for these couplings information about
obtained from can be very different from the Standard
Model prediction.Comment: Revised version with analysis done using new data from CLEO. RevTex,

And Anomalous Gauge Boson Couplings
We study in the Standard Model and
due to anomalous and interactions %using recent result on the
top quark mass from CDF. as a function of the top quark mass. In the Standard
Model, is in the range for the
central value of top quark mass reported by CDF. The anomalous gauge couplings
can have large contributions to the violating amplitude in . Within the allowed regions for the anomalous gauge
couplings, can be dramatically different from the standard
model prediction.Comment: 17 pages plus one figure (available from the author upon request),
