CP Violation Beyond the Standard Model

I review CP-violating signals of physics beyond the standard model in the B system. I examine the prospects for finding these effects at future colliders, with an emphasis on hadron machines.Comment: 11 pages, plain latex, no figures.

CP Violation in the B System: Measuring New-Physics Parameters

I review CP violation in the standard model (SM). I also describe the predictions for CP violation in the B system, along with signals for physics beyond the SM. I stress the numerous contributions of Pat O'Donnell to this subject. Finally, I discuss a new method for measuring new-physics parameters in B decays. This knowledge will allow us to partially identify any new physics which is found, before its direct production at high-energy colliders.Comment: 13 pages, 6 figures (included), plain latex.

New Physics and the Unitarity Triangle

After reviewing the present experimental constraints on the unitarity triangle, I discuss the various ways in which new physics can manifest itself in measurements of the parameters of the unitarity triangle. Apart from one exception, which I describe, new physics enters principally through new contributions to B0-B0(bar) mixing. Different models of new physics can be partially distinguished by looking at their effects on rare, flavour-changing $B$ penguin decays.
