Book Branching Fraction Measurement of B0 to D    pi and B  to D   0pi  and Isospin Analyses of B to D   pi Decays

Download or read book Branching Fraction Measurement of B0 to D pi and B to D 0pi and Isospin Analyses of B to D pi Decays written by B. Aubert and published by . This book was released on 2006 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using 65 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring at the Stanford Linear Accelerator Center, they measure the color-favored branching fractions {Beta}({bar B}{sup 0} {yields} D{sup +}{pi}{sup -}) = (2.63 {+-} 0.05 {+-} 0.22) x 10{sup -3}, {Beta}({bar B}{sup 0} {yields} D*{sup +}{pi}{sup -}) = (2.79 {+-} 0.08 {+-} 0.18) x 10{sup -3}, {Beta}(B{sup -} {yields} D{sup 0}{pi}{sup -}) = (4.90 {+-} 0.07 {+-} 0.23) x 10{sup -3} and {Beta}(B{sup -} {yields} D*{sup 0} {pi}{sup -}) = (5.52 {+-} 0.17 {+-} 0.43) x 10{sup -3}, where the first error is statistical and the second is systematic. With these results and the current world average for the branching fraction for the color-suppressed decay {bar B}{sup 0} {yields} D{sup (*)0}{pi}{sup 0}, the cosines of the strong phase difference {delta} between the I = 1/2 and I = 3/2 isospin amplitudes are determined to be cos{sigma} = 0.860{sub -0.006-0.028}{sup +0.007+0.029} for the {bar B} {yields} D{pi} process and cos{sigma} = 0.917{sub -0.016-0.051}{sup +0.018+0.059} for the {bar B} {yields} D*{pi} process. The results for cos{delta} suggest that final-state interactions are presented in the D{pi} system.

Book Measurement of the Branching Fraction for B      D0 K

Download or read book Measurement of the Branching Fraction for B D0 K written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of the branching fraction for the decay B[sup -] [yields] D[sup 0]K*[sup -] using a sample of approximately 86 million B[bar B] pairs collected by the BABAR detector from e[sup +]e[sup -] collisions near the [Upsilon](4S) resonance. The D[sup 0] is detected through its decays to K[sup -] [pi][sup +], K[sup -][pi][sup +][pi][sup 0] and K[sup -] [pi][sup +][pi][sup -][pi][sup +], and the K*[sup -] through its decay to K[sub S][sup 0] [pi][sup -].

Book Measurement of the Branching Fraction and CP Content for the Decay B   2 D  D

Download or read book Measurement of the Branching Fraction and CP Content for the Decay B 2 D D written by and published by . This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report a measurement of the branching fraction of the decay B° 2!D*D*−1 and of the CP-odd component of its final state using the BABAR detector. With data corresponding to an integrated luminosity of 20.4 fb−1 collected at the [Upsilon](4S) resonance during 1999-2000, we have reconstructed 38 candidate signal events in the mode B° 2!D*D*−1 with an estimated background of 6.2 ± 0.5 events. From these events, we determine the branching fraction to be [Beta](B° 2!D*+D*−1) = (8.3 ± 1.6(stat) ± 1.2(syst)) x 10−4. The measured CP-odd fraction of the final state is 0.22 ± 0.18(stat) ± 0.03(syst).

Book Branching Fraction Measurements of B     Eta C K Decays

Download or read book Branching Fraction Measurements of B Eta C K Decays written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the decays B[sup +] [yields] [eta][sub c]K[sup +] and B[sup 0] [yields] [eta][sub c]K[sup 0], where the [eta][sub c] is reconstructed in the K[sub S][sup 0] K[sup [+-]] [pi][sup [-+]] and K[sup +]K[sup -] [pi][sup 0] decay modes. Results are based on a sample of 86 million B[bar B] pairs collected with the BABAR detector at the SLAC e[sup +]e[sup -] B Factory. We measure the branching fractions [Beta](B[sup +] [yields] [eta][sub c]K[sup +]) = (1.34 [+-] 0.09 [+-] 0.13 [+-] 0.41) x 10[sup -3] and [Beta](B[sup 0] [yields] [eta][sub c]K[sup 0]) = (1.18 [+-] 0.16 [+-] 0.13 [+-] 0.37) x 10[sup -3], where the first error is statistical, the second is systematic, and the third reflects the [eta][sub c] branching fraction uncertainty. In addition, we search for B [yields] [eta][sub c]K events with [eta][sub c] [yields] 2(K[sup +]K[sup -]) and [eta][sub c] [yields] [phi][phi] and determine the [eta][sub c] decay branching fraction ratios [Beta]([eta][sub c] [yields] 2(K[sup +]K[sup -]))/[Beta]([eta][sub c] [yields] K[bar K][pi]) = (2.3 [+-] 0.7 [+-] 0.6) x 10[sup -2] and [Beta]([eta][sub c] [yields] [phi][phi])/[Beta]([eta][sub c] [yields] K[bar K][pi]) = (5.5 [+-] 1.4 [+-] 0.5) x 10[sup -2].

Book Measurements of the Branching Fraction and Time Dependent CP Asymmetries of B0 to J Psi Pi0 Decays

Download or read book Measurements of the Branching Fraction and Time Dependent CP Asymmetries of B0 to J Psi Pi0 Decays written by B. Aubert and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present measurements of the branching fraction and time-dependent CP asymmetries in B{sup 0} {yields} J/{psi} {pi}{sup 0} decays based on (231.8 {+-} 2.6) x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC during the years 1999-2004. We obtain a branching fraction {Beta}(B{sup 0} {yields} J/{psi}{pi}{sup 0}) = (1.94 {+-} 0.22 (stat) {+-} 0.17 (syst)) x 10{sup -5}. They also measure the CP asymmetry parameters C = -0.21 {+-} 0.26 (stat) {+-} 0.09 (syst) and S = -0.68 {+-} 0.30 (stat) {+-} 0.04 (syst). All results presented in this paper are preliminary.
