The BOSS Lyman-alpha Forest Sample from SDSS Data Release 9
Khee-Gan Lee, Stephen Bailey, Leslie E. Bartsch +50
We present the BOSS Lyman-alpha (Lya) Forest Sample from SDSS Data Release 9, comprising 54,468 quasar spectra with zqso > 2.15 suitable for Lya forest analysis. This data set prob…
Search for a Low-Mass Scalar Higgs Boson Decaying to a Tau Pair in Single-Photon Decays of Upsilon(1S)
J. P. Lees, others
We search for a low-mass scalar CP-odd Higgs boson, A0, produced in the radiative decay of the Upsilon resonance and decaying into a tau+tau- pair: Upsilon(1S)->gamma A0. The produ…
The Multi-Object, Fiber-Fed Spectrographs for SDSS and the Baryon Oscillation Spectroscopic Survey
Stephen Smee, James E. Gunn, Alan Uomoto +61
We present the design and performance of the multi-object fiber spectrographs for the Sloan Digital Sky Survey (SDSS) and their upgrade for the Baryon Oscillation Spectroscopic Sur…
The branching fraction of tau --> pi- K0S K0S (pi0) nu decays
J. P. Lees
We present a study of tau- --> pi- K0S K0S (pi0) nu and tau- --> K- K0S K0S (pi0) nu decays using a dataset of 430 million tau lepton pairs, corresponding to an integrated luminosi…
Search for resonances decaying to eta_c pi+ pi- in two-photon interactions
The BABAR Collaboration, J. P. Lees, others
We report a study of the process gamma gamma -> X -> eta_c pi+ pi-, where X stands for one of the resonances chi_{c2}(1P), eta_c(2S), X(3872), X(3915), or chi_{c2}(2P). The analysi…
Evidence for an excess of B -> D(*) Tau Nu decays
The BaBar Collaboration
Based on the full BaBar data sample, we report improved measurements of the ratios R(D(*)) = B(B -> D(*) Tau Nu)/B(B -> D(*) l Nu), where l is either e or mu. These ratios are sens…
