This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We use a global fit to determine the form factor slopes and branching fractions of the decays B --> Dlnu and B --> D*lnu. We reconstruct Dl pairs and construct a 3-dimensional distribution binned in lepton momentum, D momentum and cosTheta(B-Dl). These kinematic variables provide good separation between the signal and background. We fit electron and muon samples separately and combine them after calculating systematic uncertainties. The form factor slopes, rhoD^2 for B --> Dlnu and rho^2 for B --> D*lnu decays, are measured to be rhoD^2 = 1.22 +- 0.04 +- 0.07 and rho^2 = 1.21 +- 0.02 +- 0.07, where the errors are statistical and systematic, respectively. Branching fractions are fitted to be B(B+ --> D0lnu) = (2.36 +- 0.03 +- 0.12) % and B(B^+ --> D*0lnu) = (5.37 +- 0.02 +- 0.21) %. We use these results to determine the products, G(1)|Vcb| = (43.8 +- 0.8 +- 2.3)*10^{-3} and F(1)|Vcb| = (35.7 +- 0.2 +- 1.2)*10^{-3} of the form factors at zero recoil and the CKM matrix element |Vcb|, from which |Vcb| can be extracted using theoretical input.

Available in PDF, EPUB and Kindle. Book excerpt: The authors present a preliminary measurement of R[sub 1], and R[sub 2], and [rho][sup 2], which are the three parameters used to characterize the B [yields] D*[ell][bar [nu]][sub e] form factors (A[sub 1], V, and A[sub 2]). They use 85 x 10[sup 6] B[bar B]-pairs accumulated on the [Upsilon](4S) resonance at PEP-II. In this analysis they use the decay mode [bar B][sup 0] [yields] D[sup +]*e[sup -][bar [nu]] and its charge conjugate. The D*[sup +] is reconstructed in the channel D*[sup +] [yields] D[sup 0][pi][sup +] and the D[sup 0] in the channel D[sup 0] [yields] K[sup -][pi][sup +]. They parameterize the form factors in terms of their ratios (determined by the parameters R[sub 1] and R[sub 2]) and the common slope [rho][sup 2] in the variable w (a quantity related to the momentum transfer in the decay process). These parameters are determined via an unbinned maximum likelihood fit to the distributions in four kinematic variables (three decay angles and w). The results are R[sub 1] = 1.328 [+-] 0.055 [+-] 0.025 [+-] 0.025 and R[sub 2] = 0.920 [+-] 0.044 [+-] 0.020 [+-] 0.013 for the ratios and [rho][sup 2] = 0.769 [+-] 0.l039 [+-] 0.019 [+-] 0.032 for the slope. The stated errors are the statistical uncertainty from the data, statistical uncertainty from the size of the Monte Carlo sample and the systematic uncertainty, respectively.

Available in PDF, EPUB and Kindle. Book excerpt: We measure the dependence of {bar B}° → D*e−{bar {nu}}{sub e} on the decay angles and momentum transfer. The data sample consists of ≈ 86 x 106 B{bar B}-pairs accumulated on the?(4S) resonance by the BABAR detector at the asymmetric e+e− collider PEP-II. We specify the three form factors by two ratios R1 and R2, and by a single parameter?2 characterizing the polynomial representing h{sub A1}, the function which describes the momentum-transfer dependence of the form factor A1. We determine R1, R2, and?2 using an unbinned maximum likelihood fit to the full decay distribution. The results are R{sub 1} = 1.396 ± 0.060 ± 0.035 ± 0.027, R2 = 0.885 ± 0.040 ± 0.022 ± 0.013, and?2 = 1.145 ± 0.059 ± 0.030 ± 0.035. The stated uncertainties are the statistical from the data, statistical from the size of the Monte Carlo sample and the systematic uncertainty, respectively. In addition, based on this measurement, we give an updated value for the CKM matrix element.

This book was released on 2007 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of B([pi]0 2!e+e-[gamma])/B([pi]0 2![gamma][gamma]) using data taken in 1999 by the E832 KTeV experiment at Fermilab. The [pi]0s were produced by KL decays in flight that are fully reconstructed. They find 63,693 KL 2!3[pi]0 2![gamma][gamma] [gamma][gamma] e+e-[gamma] decays in KTeV data (an increase of a factor of ~ 20 in event statistics over previous experiments), and normalize to KL 2!3[pi]0 2!6[gamma], to extract B([pi]0 2!e+e-[gamma], me+e-> 15 MeV/c2

This book was released on 2007 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of B(?0 → e+e-?)/B(?0 → ??) using data taken in 1999 by the E832 KTeV experiment at Fermilab. The ?0s were produced by KL decays in flight that are fully reconstructed. They find 63,693 KL → 3?0 → ?? ?? e+e-? decays in KTeV data (an increase of a factor of ̃20 in event statistics over previous experiments), and normalize to KL → 3?0 → 6?, to extract B(?0 → e+e-?, me+e- > 15 MeV/c2/sup)/B(?sup0 → ??) = (3.920 ± 0.016 ± 0.036) x 10sup-3/sup, where the first error is statistical and the second is systematic. Using the Mikaelian and Smith prediction for the esup+/supesup-/sup mass spectrum as implemented in the KTeV Monte Carlo to correct to the full esup+/supesup-/sup mass range yields B(?sup0/sup → esup+/supesup-/sup?)/B(?sup0

Book excerpt: The articles in this book review hybrid experimental-computational methods applied to soft tissues which have been developed by worldwide specialists in the field. People developing computational models of soft tissues and organs will find solutions for calibrating the material parameters of their models; people performing tests on soft tissues will learn what to extract from the data and how to use these data for their models and people worried about the complexity of the biomechanical behavior of soft tissues will find relevant approaches to address this complexity.
