This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a study of the decays B− --> D*°?− and B− --> D*°K−, where the D*° decays into D°?°, with the D° reconstructed in the CP eigenstates K−K and?−?+ and in the (non-CP) channels K−?+, K−?+?+?−, and K−?+?°. They use an unbinned maximum likelihood fit to measure the signal yields. Using a sample of about 123 million?(4S) decays into B{bar B} pairs, they measure the ratios of decay rates.

This book was released on 2003 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a study of B{sup -} {yields} D{sub CP}{sup 0} K{sup -} decays, where D{sub CP}{sup 0} is reconstructed in CP-event channels, based on a sample of 88.8 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring. They measure the ratio of Cabibbo-suppressed to Cabibbo-favored branching fractions {Beta}(B{sup -} {yields} D{sub CP}{sup 0} K{sup -})/{Beta}(B{sup -} {yields} D{sub CP}{sup 0}{pi}{sup -}) = (8.8 {+-} 1.6(stat) {+-} 0.5(syst)) x 10{sup -2} and the CP asymmetry A{sub CP} = 0.07 {+-} 0.17(stat) {+-} 0.06(syst). The authors also measure {Beta}(B{sup -} {yields} D{sup 0}K{sup -})/{Beta}(B{sup -} {yields} D{sup 0}{pi}{sup -}) = (8.31 {+-} 0.35(stat) {+-} 0.20(syst)) x 10{sup -2} using a sample of 61.0 million B{bar B} pairs.

Download or read book Measurement of Branching Fraction Ratios and CP Asymmetries in B -]D0 CPK Decays with the BABAR Detector written by and published by . This book was released on 2010 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goals of the BABAR experiment are the detection of CP violation (CPV) in the B meson system, the precise measurement of some of the elements of the CKM matrix and the measurement of the rates of rare B meson decays. At present, BABAR has achieved major successes: (1) the discovery, in neutral B decays, of direct and mixing-induced CP violation; (2) accurate measurements of the magnitudes of the CKM matrix elements.

This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have reconstructed B− --> D°K− decays with D° mesons decaying to non-CP (K−?), CD-even (K−K+,?−?+) and CP-odd (K°{sub s}?°) eigenstates. They have measured the CP asymmetries A{sub CP{sup +}} = 0.40 ± 0.15(stat) ± 0.08(syst), A{sup CP{sup -}} = 0.21 ± 0.17(stat) ± 0.07(syst), and the double ratio of branching fractions R+ = 0.87 ± 0.14(stat) ± 0.06(syst), R− = 0.80 ± 0.14(stat) ± 0.08(syst). These results improve the previous existing measurements from BABAR. All results presented in this document are preliminary.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present preliminary observations of the decays of charged B mesons to a K* and a D[sup 0] where the latter particle is seen in final states of even and odd CP. They express the results in terms of R[sub CP] and A[sub CP]. With more statistics, these quantities will constrain [tau][sub B], the ratio of amplitudes defined in equations provided and the angle [gamma] of the unitary triangle by application of the Gronau-London-Wyler method.

Book excerpt: We present a study of the decay B− 2!D{sub (CP)}° K− and its charge conjugate, where D{sub (CP)}° is reconstructed in CP-even, CP-odd, and non-CP flavor eigenstates, based on a sample of 232 million [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the PEP-II ee− storage ring.

Available in PDF, EPUB and Kindle. Book excerpt: We present updated measurements of time-dependent CP asymmetries in fully reconstructed neutral B decays containing a charmonium meson. The measurements reported here use a data sample of (465 ± 5) x 106 [Upsilon](4S) → B{bar B} decays collected with the BABAR detector at the PEP-II B factory. The time-dependent CP asymmetry parameters measured from J/[psi]K{sub S}°, J/[psi]K{sub L}°, [psi](2S)K{sub S}°, [chi]{sub c1}K{sub S}°, [eta]{sub c}K{sub S}°, and J/[psi]K*° decays are: (1) C{sub f} = 0.026 ± 0.020(stat) ± 0.016(syst); and (2) S{sub f} = 0.691 ± 0.029(stat) ± 0.014(syst).
