Spatial Barriers and the Formation of Global Art Cities: The Case of Tokyo

This paper addresses a neglected dimension of global cities research: how the idea of economic concentration, its surplus and consequent global influence can be applied to the art world. The research presented here relates to Tokyo as a well‐known example of a global city, advancing existing understandings of Tokyo from the neglected perspective of the arts. Based on qualitative and quantitative research by the author, including cultural and spatial mapping, interviews, ethnographic observations and visual documents, the findings confirm that the role of space and materiality is overlooked in global cities research. The results demonstrate the active contribution and intervention of spatial patterns in the formation of artistic activities. A number of Tokyo's spatial features have an inhibiting effect that shifts artistic activities underground, creating asymmetries in the constitution of symbolic meanings in the city and a failure to openly stimulate artistic practices. As a consequence, Tokyo's vivid art world remains invisible not only to outsiders but to Tokyo itself

Improved Measurement of the Cabibbo-Kobayashi-Maskawa Angle α Using B0(B¯)→ρ+ρ- Decays

We present results from an analysis of B0(B̅ 0)→ρ+ρ- using 232×106 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We measure the longitudinal polarization fraction fL=0.978±0.014(stat)+0.021/-0.029(syst) and the CP-violating parameters SL=-0.33±0.24(stat)+0.08/-0.14(syst) and CL=-0.03±0.18(stat)±0.09(syst). Using an isospin analysis of B→ρρ decays, we determine the unitarity triangle parameter α. The solution compatible with the standard model is α=(100±13)°

Improved measurement of the Cabibbo-Kobayashi-Maskawa angle α using B0(B)→p+p- decays

We present results from an analysis of B0(B¯¯¯0)→ρ+ρ− using 232×106 Υ(4S)→BB¯¯¯ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We measure the longitudinal polarization fraction fL=0.978±0.014(stat)+0.021−0.029(syst) and the CP-violating parameters SL=−0.33±0.24(stat)+0.08−0.14(syst) and CL=−0.03±0.18(stat)±0.09(syst). Using an isospin analysis of B→ρρ decays, we determine the unitarity triangle parameter α. The solution compatible with the standard model is α=(100±13)°
