Private school choice among Muslim parents: the public–private school decision in Delhi, India

This article examines Muslim parents’ private school choice, their understanding of public–private schooling and how they navigate the choice between fee-free public schools and fee-charging private schools. This article draws on qualitative data from open-ended, semi-structured interviews with 38 parents from Muslim-majority areas in Delhi, India. The findings show that parents choose private schools for several reasons, such as their proximity, discipline, emphasis on Islamic teachings and values, safety and caring teachers. The analysis suggests that structural and social factors influence and construct parents’ choice of a particular school. The neighbourhood where they reside, their minority status, their socio-economic and demographic profile, and the type of schools that are available to them influence their decision making

Branching fraction and CP asymmetries of B0→KS0KS0KS0

We present measurements of the branching fraction and time-dependent CP-violating asymmetries in B0→K0SK0SK0S decays based on 227×106 Υ(4S)→BB decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain a branching fraction of (6.9+0.9−0.8±0.6)×10−6, and CP asymmetries C=−0.34+0.28−0.25±0.05 and S=−0.71+0.38−0.32±0.04, where the first uncertainties are statistical and the second systematic

Measurement of the CP violating asymmetry amplitude sin 2beta

We present results on time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 88 million Y(4S) --> B Bbar decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We study events in which one neutral B meson is fully reconstructed in a final state containing a charmonium meson and the other B meson is determined to be either a B0 or B0bar from its decay products. The amplitude of the CP-violating asymmetry, which in the Standard Model is proportional to sin2beta, is derived from the decay-time distributions in such events. We measure sin2beta = 0.741 +/- 0.067 (stat) +/- 0.034 (syst) and |lambda| = 0.948 +/- 0.051 (stat) +/- 0.030 (syst). The magnitude of lambda is consistent with unity, in agreement with the Standard Model expectation of no direct CP violation in these modes.Comment: 7 pages, 2 postscript figures, submitted to PR

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)°
