Measurement of the branching fractions for the exclusive decays of B0 and B+ to anti-D(*) D(*) K
No full textThis is the pre-print version of the Article. The official published version can be accessed from the links below. Copyright @ 2003 APSWe report the observation of 823±57 B0 and 970±65 B+ decays to doubly charmed final states D(*)D(*)K, where D(*) and D(*) are fully reconstructed and K is either a K± or a K0. We use a sample of 82.3±0.9 million BB̅ events collected between 1999 and 2002 with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center. The 22 possible B decays to D(*)D(*)K are reconstructed exclusively and the corresponding branching fractions or limits are determined. The branching fractions of the B0 and of the B+ to D(*)D(*)K are found to be B(B0→D(*)D(*)K)=[4.3±0.3(stat)±0.6(syst)]%, B(B+→D(*)D(*)K)=[3.5±0.3(stat)±0.5(syst)]%. A search for decays to orbitally excited Ds states, B⃗D(*)DsJ+ (DsJ+→D(*)0K+), is also performed. No statistically significant contributions from Ds1+(2536)→D*0K+ and DsJ+(2573)→D0K+ to the D(*)D(*)0K+ final state are found and we set 90% C.L. limits on their production rates.This work was supported by the US Department of Energy and National Science Foundation, the Natural Sciences and Engineering Research Council (Canada), Institute of High Energy Physics (China), the Commissariat `a l’Energie Atomique and Institut National de Physique Nucl´eaire et de Physique des Particules (France), the Bundesministerium f¨ur Bildung und Forschung and Deutsche Forschungsgemeinschaft (Germany), the Istituto Nazionale di Fisica Nucleare (Italy), the Foundation for Fundamental Research on Matter (The Netherlands), the Research Council of Norway, the Ministry of Science and Technology of the Russian Federation, and the Particle Physics and Astronomy Research Council (United Kingdom).

Measurement of branching fractions of color-suppressed decays of the (B)over-bar(0) meson to D-(*)0 pi(0), D-(*)0 eta, D-(*)0 omega, and D-0 eta `
No full textUsing a sample of 88.8×10^6 BB̅ events collected with the BABAR detector at the PEP-II storage rings at the Stanford Linear Accelerator Center, we measure the branching fractions of seven color-suppressed B-meson decays: B(B0→D0π0)=[2.9±0.2(stat)±0.3(syst)]×10-4, B(B0→D*0π0)=[2.9±0.4(stat)±0.5(syst)]×10-4, B(B0→D0η)=[2.5±0.2(stat)±0.3(syst)]×10-4, B(B0→D*0η)=[2.6±0.4(stat)±0.4(syst)]×10-4, B(B0→D0ω)=[3.0±0.3(stat)±0.4(syst)]×10-4, B(B0→D*0ω)=[4.2±0.7(stat)±0.9(syst)]×10-4, and B(B0→D0η′)=[1.7±0.4(stat)±0.2(syst)]×10-4. We set the 90% confidence-level upper limit: B(B0→D*0η′)<2.6×10-4. The channels B0→D*0η, D*0ω, and D0η′ are seen with more than five-sigma statistical significance. All of these branching fractions are significantly larger than theoretical expectations based on the “naive” factorization model
Measurement of B0 --> Ds(*)+D*- branching fractions and B0 --> Ds*+D*- polarization with a partial reconstruction technique
No full textWe present a study of the decays B0→Ds (*)+D*-, using 20.8 fb-1 of e +e- annihilation data recorded with the BABAR detector. The analysis is conducted with a partial reconstniction technique, in which only the Ds(*)+ and the soft pion from the D*- decay are reconstructed. We measure the branching fractions B(B0→Ds+D*-) = (1.03±0.14±0.13±0.26)% and B(B0→D* s+D*-) = (1.97±0.15±0. 30±0.49)%, where the first error is statistical, the second is systematic, and the third is the error due to the Ds+ → φπ+ branching fraction uncertainty. From the B 0→D*s+D*- angular distributions, we measure the fraction of longitudinal polarization ΓL/Γ = (51.9±5.0±2.8)%, which is consistent with theoretical predictions based on factorization
Measurements of Branching Fractions and Dalitz Distributions for B^0 \to D^{(*)}\pmK^0\pi^{\pm} Decays
No full textWe present measurements of the branching fractions for the three-body decays B0-->D(*)-/+K0pi± and their resonant submodes B0-->D(*)-/+K*± using a sample of approximately 88×106 B[overline B] pairs collected by the BABAR detector at the SLAC PEP-II asymmetric energy storage ring. We measure: [script B](B0-->D-/+K0pi±)=(4.9±0.7stat±0.5syst)×10-4, [script B](B0-->D*-/+K0pi±)=(3.0±0.7stat±0.3syst)×10-4, [script B](B0-->D-/+K*±)=(4.6±0.6stat±0.5syst)×10-4, [script B](B0-->D*-/+K*±)=(3.2±0.6stat±0.3syst)×10-4. From these measurements we determine the fractions of resonant events to be f(B0-->D-/+K*±)=0.63±0.08stat±0.04syst and f(B0-->D*-/+K*±)=0.72±0.14stat±0.05syst

The analysis is conducted with a partial reconstruction technique, in which only the Ds(*)+ and the soft pion from the D*- decay are reconstructed.

From the B0→Ds*+D*- angular distributions, we measure the fraction of longitudinal polarization ΓL/Γ=(51.9±5.0±2.8)%, which is consistent with theoretical predictions based on factorization
Experimental Data-Effect of Fetal Bovine Serum in SH-SY5Y Proliferation
No full textFetal bovine serum (FBS) is the most common growth supplement used in the cell culture, which is a cocktail of low and high molecular weight biomolecules including growth-promoting and growth-inhibiting factors for cell attachment, growth, and proliferation. The high level of undefined proteins in FBS may cause unwanted cell stimulation.[1] Therefore, serum-free media is usually used during experiments. Unfortunately, when studying the long-term effects of drugs or chemicals, this serum starvation may lead to cell death in the control samples. In this experiment, we study the effect of the FBS in the proliferation of SH-SY5Y neuroblastoma cells. SH-SY5Y is a human-derived cell line used as an in vitro model of neuronal function and differentiation particularly to study neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease.[2] We monitored the proliferation of SH-SY5Y cells in Dulbecco's Modified Eagle Medium (DMEM) containing different proportions of FBS for 7 days using a hemocytometer. These results can be used to design cytotoxicity experiments by choosing a suitable proportion of FBS in the DMEM for the SH-SY5Y in vitro system.References:(1) van der Valk, J.; Bieback, K.; Buta, C.; Cochrane, B.; Dirks, W.

Measurement of ratios of fragmentation fractions for bottom hadrons in p(p)over-bar collisions at root s=1.96 TeV
No full textThis paper describes the first measurement of b-quark fragmentation fractions into bottom hadrons in Run II of the Tevatron Collider at Fermilab. The result is based on a 360 pb(-1) sample of data collected with the CDF II detector in p (p) over bar collisions at root s = 1.96 TeV. Semileptonic decays of (B) over bar (0), B-, and (B) over bar (0)(s) mesons, as well as Lambda(0)(b) baryons, are reconstructed. For an effective bottom hadron p(T) threshold of 7 GeV/c, the fragmentation fractions are measured to be f(u)/f(d)=1.054 +/- 0.018(stat)(-0.045)(+0.025)(sys)+/- 0.058(B), f(s)/(f(u)+f(d))=0.160 +/- 0.005(stat)(-0.010)(+0.011)(sys)(-0.034)(+0.057)(B), and f(Lambda b)/(f(u)+f(d))=0.281 +/- 0.012(stat)(-0.056)(+0.058)(sys)(-0.087)(+0.128)(B), where the uncertainty B is due to uncertainties on measured branching ratios. The value of f(s)/(f(u)+f(d)) agrees within one standard deviation with previous CDF measurements and the world average of this quantity, which is dominated by LEP measurements. However, the ratio f(Lambda b)/(f(u)+f(d)) is approximately twice the value previously measured at LEP. The approximately 2 sigma discrepancy is examined in terms of kinematic differences between the two production environments
Measurement of mass and width of the excited charmed meson states D-1(0) and D-2(*0) at CDF
No full textWe report on precision measurements of the masses and widths of the narrow, orbitally excited states D-1(0) and D-2(*0) using the CDF II detector at the Fermilab Tevatron. Both states (collectively called D-**) are reconstructed in the decay channel D-**-> D*+pi(-). The D-2(*0) is also reconstructed in the D-**-> D+pi(-) channel. Using a data set with an integrated luminosity of 210 pb(-1), the measured masses and widths for the D-1(0) are 2421.7 +/- 0.7 +/- 0.6 MeV/c(2) and 20.0 +/- 1.7 +/- 1.3 MeV/c(2) respectively, while for the D-2(*0) they are 2463.3 +/- 0.6 +/- 0.8 MeV/c(2) and 49.2 +/- 2.3 +/- 1.2 MeV/c(2). These values are currently the single best measurements available
