Wolfenstein parametrization reexamined.
The Wolfenstein parametrization of the 3 × 3 Kobayashi-Maskawa (KM) matrix V is modified by keeping its unitarity up to the accuracy of O(λ). This modification can self-consistently lead to the off-diagonal asymmetry of V : |Vij| 2 − |Vji| 2 = Z ∑ k ǫijk with Z ≈ Aλ(1 − 2ρ), which is comparable in magnitude with the Jarlskog parameter of CP violation J ≈ Aλη . We constrain the ranges of J and Z...
متن کاملWolfenstein-like Parametrization of the Neutrino Mixing Matrix
We show that the 3× 3 lepton flavor mixing matrix V can be expanded in powers of a Wolfenstein-like parameter Λ ≡ |Vμ3| ∼ 1/ √ 2 , which measures the strength of flavor conversion in atmospheric neutrino oscillations. The term of O(Λ2) is responsible for the large flavor mixing in solar neutrino oscillations. The Dirac phase of CP violation enters at or below O(Λ6), and the Majorana phases of C...
متن کاملSocial health insurance reexamined.
Social health insurance (SHI) is enjoying something of a revival in parts of the developing world. Many countries that have in the past relied largely on tax finance (and out-of-pocket payments) have introduced SHI, or are thinking about doing so. And countries with SHI already in place are making vigorous efforts to extend coverage to the informal sector. Ironically, this revival is occurring ...
متن کاملKaluza-klein Solitons Reexamined
In (4 + 1) gravity the assumption that the five-dimensional metric is independent of the fifth coordinate authorizes the extra dimension to be either spacelike or timelike. As a consequence of this, the time coordinate and the extra coordinate are interchangeable, which in turn allows the conception of different scenarios in 4D from a single solution in 5D. In this paper, we make a thorough inv...
متن کاملPrison Crowding Research Reexamined
Dramatic increases in the United States' inmate population has raised new concerns about prison crowding. Although growth in prison capacity has lagged slightly behind that of the inmate population, there is no consistent evidence that crowding is associated with mortality, morbidity (defined as clinic utilization), recidivism, violence, or other pathological behaviors. This paper reviews the m...
