Scientific Drivers for ESO Future VLT/VLTI Instrumentation Springer (2003)

Abstract:

We describe an instrument concept that will provide simultaneous spectra for a million spatial samples on the sky. With the proposed field of view and spectral resolution, it will be able to measure redshifts and line strengths for around 2-4000 z~3-7 galaxies in a 16 night campaign. The main science driver is to obtain a complete census of the star formation properties of galaxies with 2.5

Abstract:

We report on determinations of |Vub| resulting from studies of the branching fraction and q2 distributions in exclusive semileptonic B decays that proceed via the b→u transition. Our data set consists of the 9.7×106 BB̄ meson pairs collected at the Y(4S) resonance with the CLEO II detector. We measure B(B0→π -ℓ+ν)=(1.33±0.18±0.11± 0.01±0.07)×10-4 and B(B0→ρ -ℓ+ν)=(2.17±0.34-0.54+0.47±0.41 ±0.01)×10-4, where the errors are statistical, experimental systematic, systematic due to residual form-factor uncertainties in the signal, and systematic due to residual form-factor uncertainties in the cross-feed modes, respectively. We also find B(B+→ηℓ+ν)=(0.84±0.31± 0.16±0.09)×10-4, consistent with what is expected from the B→πℓν mode and quark model symmetries. We extract |V ub| using light-cone sum rules for 0≤q2<16GeV 2 and lattice QCD for 16 GeV2≤q2
