Electro-Weak Penguin and Leptonic Decays in BaBar

Pages : 8
Book Description
Electro-weak penguin and leptonic decays provide an indirect probe for physics beyond the Standard Model and contribute to the determination of Standard Model parameters. Copious quantities of B mesons produced at the B-Factories permit precision measurements of the electro-weak penguin decays and searches for leptonic decays. We review the current experimental status of b {yields} s(d){gamma}, B{sup 0} {yields} D*{sup 0}{gamma}, b {yields} s{ell}{sup +}{ell}{sup -} and finally B{sup +} {yields} {tau}{sup +}{nu}{sub {tau}} decays at BABAR.

Book Description
Electroweak penguin decays provide a promising hunting ground for Physics beyond the Standard Model (SM). The decay B[yields] X[sub s][gamma], which proceeds through an electromagnetic penguin loop, already provides stringent constraints on the supersymmetric (SUSY) parameter space. The present data samples of[approx]1 x 10[sup 8] B[bar B] events allow to explore radiative penguin decays with branching fractions of the order of 10[sup -6] or less. In this brief report they discuss a study of B[yields] K*[ell][sup+][ell][sup -] decay modes and a search for B[yields][rho]([omega])[gamma] decays.

Book Description
Recent BABAR results on rare B decays involving flavour-changing neutral currents or purely leptonic final states are presented. New measurements of the CP asymmetries in B [yields] K*[gamma], B [yields] K*[sub 2](1430)[gamma], and b [yields] s[gamma] are reported, as well as a new measurement of the B [yields] K*[gamma] branching fraction. Also reported are updated limits on B [yields] [mu][nu] and recent measurements of B [yields] K(*)[ell][ell] and b [yields] s[ell][ell]. The data sample comprises 123 [center-dot] 10[sup 6] [Upsilon](4S) [yields] B[bar B] decays collected with the BABAR detector at the PEP-II e[sup +]e[sup -] storage ring.

Book Description
We summarize results on a number of observations of penguin dominated radiative decays of the B meson. Such decays are forbidden at tree level and proceed via electroweak loops. As such they may be sensitive to physics beyond the standard model. The observations have been made at the BaBar experiment at PEPII, the asymmetric B factory at SLAC.

Book Description
Radiative and electroweak penguin decays of B mesons are flavor-changing-neutral-current processes that provide powerful ways to test the Standard Model at the one-loop level, to search for the effects of new physics, and to extract Standard Model parameters such as CKM matrix elements and quark masses. The large data samples obtained by the B-factory experiments BaBar and Belle, together with an intensive theoretical effort, have led to significant progress towards understanding these rare decays. Recent experimental results include the measurements of the b 2!d[gamma] decays B 2![rho]([omega])[gamma], the observation of B 2!K(*)ll− decays (together with studies of the associated kinematic distributions), and improved measurements of the inclusive B 2!Xs[gamma] rate and photon energy spectrum.
