B - Factories
The evolution of B-Factories is discussed, and comments are made about the common features of present-day asymmetric storage ring collider designs. * Work supported by Department of Energy contract DE-AC03-76SF00515. Presented at the 4th International Symposium on Heavy E’lavour Physics, Orsay, France, June 25-29, 1991 There was a symposium Progress on B-Factories the day before the Heavy Flavo...
متن کاملB-factories* - Ellio?t
(El a-ABSTRACT We briefly review the physics of CP violation and the interest of studying this phenomenon in the B-meson system. The need for very large numbers of B-decays is shown, and a number of approaches for B-factories are compared. In particular, e+e-linear and circular colliders are discussed in some detail, with specific examples presented .
متن کاملSuper B Factories
After the establishment of the Kobayashi-Maskawa mechanism of CP violation at the two B factories, possibilities to increase the integrated luminosity by two orders of magnitude have been investigated, since it seems to be the amount needed to find physics beyond the Standard Model through CP violating and other observables in rare B meson decays, D meson decays and τ lepton decays. This report...
متن کاملSemileptonic B Decays at the B Factories
Semileptonic B decays provide direct access to the CKM matrix elements Vub and Vcb, whose ratio gives a measurement of the side of the Unitarity Triangle opposite the angle β. The underlying theory of semileptonic B decays is at an advanced stage. The weak currents factorize in leptonic and hadronic parts which do not interact between each other. Moreover, the b quark mass is considerably large...
متن کاملPhysics at the B Factories
We review recent progress at the two e + e − B factories. The first measurement of CP violation and the prospects for measuring all the angles of the unitarity triangle are discussed.
