Comment: 5 pages, 6 figures, 1 table. Presented at LCWS08 Chicago, Nov. 16-20 2008
Recent activities related to the FERMI project are presented, concentrating on the re-designed beam transport optics including an assessment of second-order effects. Recent improvements to the linac are described and some details about the implementation of the FEL and its optical systems are also presented.
This report describes the present status of the detector design for SuperB. It is one of four separate progress reports that, taken collectively, describe progress made on the SuperB Project since the publication of the SuperB Conceptual Design Report in 2007 and the Proceedings of SuperB Workshop VI in Valencia in 2008. The other three reports relate to Physics, Accelerator and Computing.
We report updated branching fraction measurements of the color-suppressed decays B0bar to D0 pi0, D*0 pi0, D0 eta, D*0 eta, D0 omega, D*0 omega, D0 eta_prime, and D*0 eta_prime. We measure the branching fractions (*10^-4): BF(B0bar to D0 pi0) = 2.69 +/- 0.09 +/- 0.13, BF(B0bar to D*0 pi0) = 3.05 +/- 0.14 +/- 0.28, BF(B0bar to D0 eta) = 2.53 +/- 0.09 +/- 0.11, BF(B0bar to D*0 eta) = 2.69 +/- 0.14 +/- 0.23, BF(B0bar to D0 omega) = 2.57 +/- 0.11 +/- 0.14, BF(B0bar to D*0 omega) = 4.55 +/- 0.24 +/- 0.39, BF(B0bar to D0 eta_prime) = 1.48 +/- 0.13 +/- 0.07,and BF(B0bar to D*0 eta_prime) = 1.49 +/- 0.22 +/- 0.15. We also present the first measurement of the longitudinal polarization fraction of the decay channel D*0 omega, f_L = (66.5+/- 4.7+/- 1.5) %. In the above, the first uncertainty is statistical and the second is systematic. The result...
