‘D is for dangerous’: devolution and the ongoing decline of manufacturing in Northern England
No full textThis chapter considers the recent history, and likely future, of manufacturing in Northern England, with reference to the potential impact of initiatives related to the Northern Powerhouse agenda in this area. The chapter is structured around ‘the three Ds’ of the Northern Powerhouse: deindustrialisation, devolution and de-development. Contesting the view that the Northern Powerhouse can be understood primarily as a process of institutional or constitutional reform, it instead locates the agenda within the long (but limited) history of UK industrial policy. It argues that regional policy has always substituted for industrial policy in the UK state’s ‘horizontal’ support for manufacturing, and that devolution to Northern city-regions is therefore the ultimate expression of laissez-faire industrial policy. However, the agenda touches upon post-crisis concerns around place and empowerment, even while it serves to reduce the control of Northern citizens over their own local economies by offering only a narrow understanding of how economies develop

Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
No full textThis Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within

Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays
No full textMeasurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of phi_s=-0.019^{+0.173+0.004}_{-0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found
Berry phase in neutrino oscillations
No full textWe study the Berry phase in neutrino oscillations for both Dirac and Majorana neutrinos. In order to have a Berry phase, the neutrino oscillations must occur in a varying medium, the neutrino-background interactions must depend on at least two independent densities, and also there must be CP violation. If the neutrino interactions with matter are mediated only by the standard model W and Z boson exchanges, these conditions imply that there must be at least three generations of neutrinos. The CP violating Majorana phases do not play a role in generating a Berry phase. We show that a natural way to satisfy the conditions for the generation of a Berry phase is to have sterile neutrinos with active-sterile neutrino mixing, in which case at least two active and one sterile neutrinos are required. If there are additional new CP violating flavor changing interactions, it is also possible to have a nonzero Berry phase with just two generations.Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)0ARTICLE5null7
A study of CP violation in B±→DK±B±→DK± and B±→Dπ±B±→Dπ± decays with D→KS0K±π∓ final states
No full textA first study of CP violation in the decay modes B± → [K0S K ±π∓]Dh± and B± → [K0S K ∓π±]Dh±, where h labels a K or π meson and D labels a D0 or D0 meson, is performed. The analysis uses the LHCb data set collected in pp collisions, corresponding to an integrated luminosity of 3 fb−1. The analysis is sensitive to the CP-violating CKM phase γ through seven observables: one charge asymmetry in each of the four modes and three ratios of the charge-integrated yields. The results are consistent with measurements of γ using other decay modes
Told and Retold: Around the World with Aeos's Fables
No full textOne usually does not speak of Aesop "around the world," and so I have been curious about this attractive, large-format (9¼" x 11¼") children's book of 32 pages. The introduction supplies perspective: "many familiar stories that we call Aesop's fables are still being told around the world. You may recognize some of these stories." Berry is a linoleum block printmaker. That may give a suggestion about the strong and highly personal style of these illustrations. Berry's forms are strong and even massive. Some sense of the drama may come from viewing the two-page spread, including two text-boxes, for the first fable, "The Heron." That fable is ascribed to eastern North America; LM to East Africa; GA to East Asia; TH to southwest North America; FG to the Middle East and Asia; "The Bear and the Bees" to western South America; CP to southwest Europe; "Two Goats" to central-west Europe; and WC to North Asia. Two-page spreads interrupt the sequence of stories, as though to give a reflective pause. These pages show gatherings of the various animals mentioned in the fables. The last of them pictures Aesop too, in the same pose as we find on the dust-jacket and front-cover. GA receives an utterly positive spin. The ants reconsider, thank the grasshopper for entertaining them, and pass her some food. The grasshopper's summertime music helped them to work even harder than usual and to store extra food that they are now willing to share. "The Bear and the Bees" is also well shaped. The bear was about to eat berries when he noticed the beehive and began to nose around it. A single bee stung him on the nose. He lost his temper and attacked the whole hive. He should have eaten the berries!First printingHolly Berr
Geometric Phases in Neutral Kaon Mixing and CP violation
No full textWe studied the formalism for construction of geometric phases (Berry phases) in the neutral kaon mixing system. We explicitly calculated the geometric phases for the CP conserving and CP violating scenarios with effective meson field theory and the CP violating phase δ has been shown to be of geometrical origin.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.
