ABSTRACT
We compute the bounds from precision observables on alternative theories of electroweak symmetry breaking. We show that a cutoff as large as 3 TeV can be accommodated by the present data, without any new particles or unnatural fine tuning.
ABSTRACT
We propose a new method for measuring the Cabibbo-Kobayashi-Maskawa phase gamma using the partial rates for CP-tagged B(s) decays. Such an experiment could be performed at a very high luminosity symmetric e(+)e(-) collider operating at the Upsilon(5S) resonance, where the B(s)&Bmacr;(s) pair is produced in a state of definite CP. We also discuss CP tagging in the B(d) system at the Upsilon(4S), where a time-dependent analysis is required to compensate for the anticipated large CP violation in B(d)-&Bmacr;(d) mixing.
