Book excerpt: We present a study of the decays B{sup 0,+} --> J/???−?°K{sup 0,+}, using 467x106 B{anti B} pairs recorded with the BABAR detector. We present evidence for the decay mode X(3872) --> J/??, with product branching fractions B(B+ --> X(3872)K+) x B(X(3872) --> J/??) = [0.6 ± 0.2(stat) ± 0.1(syst)] x 10−5, and B(B° --> X(3872)K°) x B(X(3872) --> J/??) = [0.6 ± 0.3(stat) ± 0.1(syst)] x 10−5. A detailed study of the?+?−?° mass distribution from X(3872) decay favors a negative-parity assignment.

Available in PDF, EPUB and Kindle. Book excerpt: Using the decay sequence J/? →?X, X → a0{sup {plus minus}}(980)?{sup {minus plus}}, a0{sup {plus minus}}(980) →??{sup {plus minus}}, where X is the f1(1285) or?(1400), the?? vs??− Dalitz plot intensity distributions are fitted with a model containing a coupled-channel parametrization of the a0(980). Preliminary values for the spin of X, the mass and width of the a0{sup {plus minus}}(980) to??{sup {plus minus}}, and the ratio of a0+(980) coupling strengths, g{sub K}2/g{sub?}2, to {bar K}°K+ and??+ are determined. From this model, the predictions for the ratios of branching ratios r{sub X} = B(X → a0(980)?){center dot}B(a0(980) → K{bar K})/B(X → a0{sup {plus minus}}(980)?){center dot}B(a0{sup {plus minus}}(980) →??{sup {plus minus}}) are compared with those obtained from MARK III Partial Waves analyses of the decays J/? →?K{sub s}°K{sup {plus minus}}?{sup {minus plus}} and J/? →?{eta}?+?−. 12 refs., 3 figs., 4 tabs.

Book excerpt: Using data taken with the CLEO II detector, we present the first full angular analysis in the color-suppressed modes B[sup 0][yields] J/[psi] K*[sup 0] and B[sup+][yields] J/[psi] K*[sup+]. This leads to a complete determination of the decay amplitudes of these modes. In addition, we update the branching fractions for B[yields] J/[psi] K and B[yields] J/[psi] K*.

Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B{sub d} → J/[Psi] K* and B{sub s} → J/[Psi][phi] in the transversity basis. We also measure the mean lifetime of the B{sub s} mass eigenstates and the lifetime ratio. The analyses are based on approximately 2.8 fb−1 of data recorded with the D0 detector. From our measurements of the angular parameters we conclude that there is no evidence for a deviation from flavor SU(3) symmetry for these decays and that the factorization assumption is not valid for the B{sub d} → J/[Psi] K* decay.

Download or read book Study of B Meson Decays to Ppbarh Final States written by Tetiana B. Hryn'ova and published by . This book was released on 2006 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: B mesons are unique among well-established non-quarkonium mesons in their ability to decay into baryons. Baryonic B decays offer a wide range of interesting areas of study: they can be used to test our theoretical understanding of rare decay processes involving baryons, search for direct CP violation and study low-energy QCD. This thesis presents measurements of branching fractions and a study of the decay dynamics of the charmless three-body decays of B meson into p{bar p}h final states, where h = {pi}{sup +}, K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}. With a sample of 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BaBar detector, we report the first observation of the B {yields} p{bar p}K*{sup 0} decay, and provide improved measurements of branching fractions of the other modes. The distribution of the three final-state particles is of particular interest since it provides dynamical information on the possible presence of exotic intermediate states such as the hypothetical pentaquark states {Theta}*{sup ++} and {Theta}{sup +}in the m{sub pK{sup +}} and m{sub pK{sub S}{sup 0}} spectra, respectively, or glueball states (such as the tensor glueball f{sub J}(2220)) in the m{sub p{bar p}} spectrum. No evidence for exotic states is found and upper limits on the branching fractions are set. An enhancement at low p{bar p} mass is observed in all the B {yields} p{bar p}h modes, and its shape is compared between the decay modes and with the shape of the time-like proton form factor. A Dalitz plot asymmetry in B {yields} p{bar p}K{sup +} mode suggests dominance of the penguin amplitude in this decay and disfavors the possibility that the low mass p{bar p} enhancement originates from the presence of a resonance below threshold (such as the recently seen baryonium candidate at 1835 MeV/c{sup 2}). We also identify decays of the type B {yields} X{sub c{bar c}}h {yields} p{bar p}h, where h = K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}, and X{sub c{bar c}} = {eta}{sub c} or J/{psi}. In particular, we report on the evidence of the B {yields} {eta}{sub c}K*{sup +} decay and provide a measurement of the width of {eta}{sub c}.

This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the time-dependent asymmetry in the rate for [anti B][sup 0] versus B[sup 0] decays to J/[psi]K[sup 0][sub s]. The data sample consists of 198 [+-] 17 B[sup 0]/[anti B][sup 0] decays collected by the CDF detector in p[anti p] collisions at the Fermilab Tevatron, where the initial b flavor has been determined by a same-side flavor tagging technique. This asymmetry is interpreted in the Standard Model as a measurement of the CP-violation parameter sin(2[beta]). Our analysis results in sin(2[beta]) = 1:8 [+-] 1:1(stat) [+-] 0:3(syst).

Available in PDF, EPUB and Kindle. Book excerpt: We have measured the time-dependent decay rate for the process B [yields] J/[psi] K*[sup 0](892) in a sample of about 88 million [Upsilon](4S) [yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. In this sample we study flavor-tagged events in which one neutral B meson is reconstructed in the J/[psi]K*[sup 0] or J/[psi] [bar K]*[sup 0] final state. We measure the coefficients of the cosine and sine terms in the time-dependent asymmetries for J/[psi]K*[sup 0] and J/[psi][bar K]*[sup 0], find them to be consistent with the Standard Model expectations, and set upper limits at 90% C.L. on the decay amplitude ratios A([bar B][sup 0] [yields] J/[psi]K*[sup 0])/A(B[sup 0] [yields] J/[psi]K*[sup 0])

Book excerpt: We present results from BaBar experiment for the measurement of inclusive and exclusive branching fractions of B mesons into final states containing J/[psi], [psi](2S) and[chi]c. The contributions of CP even and odd amplitudes in the decay B[sup 0][yields] J/[psi]K*[sup 0] are determined from an angular analysis. We report the measurements of the branching ratios B[sup 0][yields] D*[sup+] D*[sup -] and D*[sup+] D*[sup -] K[sub S][sup 0], and the study of exclusive two-body and quasi-two-body charmless decays. The branching fraction of the decay B[sup 0][yields] K*[sup 0][gamma] has been determined and the corresponding CP asymmetry has been measured.
