We present recent measurements of the CKM angles alpha and gamma using data collected by the BaBar detector at the PEP-II asymmetric-energy ee− collider at the Stanford Linear Accelerator Center. In addition to constraints on alpha from the decays B0 2!?+?−, B0 2!?+?− and B0 2!?+?−, we also report the first measurement of time-dependent CP asymmetries in the decay B0 2!a1+(1260)?−. We present measurements of gamma in B+ 2!D(*)0 K+ decays using a Dalitz analysis in the modes D° 2!Ks?+?− and D° 2!?+?−?°.

We present a short review of the measurements of the CKM angle [gamma] performed by the BABAR experiment. We focus on methods using charged B decays, which give a direct access to [gamma] and provide the best constraints so far.

We present BABAR experiment studies to measure the CKM angle {alpha} of the Unitarity Triangle. The measurements are based on the B meson decays into the two-body state ({pi}{pi}), the quasi two-body state ({rho}{rho}), and the three-body state ({pi}{sup +}{pi}{sup -}{pi}{sup 0}). The results are obtained from data samples of about 230 million {Upsilon}(4S) {yields} B{bar B} decays collected between 1999 and 2004 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.

The authors present the results of the measurements employed by the BABAR Collaboration, to determine the value of the Cabibbo-Kobayashi-Maskawa (CKM) CP-violating phase {gamma} ({triple_bond} arg [-V{sub ud}V*{sub ub}/V{sub cd}V*{sub cb}]). These measurements are based on the studies performed with the charged B-decays B{sup -} {yields} {tilde D}{sup 0} K{sup -}, B{sup -} {yields} {tilde D}*{sup 0} K*{sup -}, where {tilde D}{sup 0} indicates either a D{sup 0} or a {bar D}{sup 0} meson. A sample of about 230 million B{bar B} pairs collected by the BABAR detector [1], at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC, is used.

Download Recent Results from the BaBar Experiment Book in PDF, ePub and Kindle
The authors present an overview of some of the most recent results from the BABAR experiment. They discuss the latest measurement of the time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates, that in the Standard Model (SM) is proportional to sin 2[beta]. They present measurements of branching fractions and CP-violating asymmetries in neutral B decays to two-body final states of charged pions and kaons, that are related to the angle [alpha] of the Unitarity Triangle. They also report the B[sup 0] lifetime measurement obtained from studying the B[sup 0] [yields] D*[sup -] [pi][sup +] and B[sup 0] [yields] D*[sup -] [rho][sup +] decay channels and the B[sup 0] [yields] D*[sup -] a[sub 1][sup +] branching fraction, obtained using a partial reconstruction technique. These measurements serve as a test and validation of the procedures required to measure the combination of CKM Unitarity Triangle angles sin(2[beta] + [gamma]).
