The influence of basin architecture and synrift salt on structural evolution during and after rifting: a case study of the Orpheus rift basin, offshore Nova Scotia and Newfoundland, Canada
No full textThe Orpheus rift basin is part of the eastern North American rift system that formed prior to the opening of Atlantic Ocean. Using 2D seismic-reflection and well data and with information from the adjacent Fundy rift basin, I have defined the styles of deformation that formed during the development of the Orpheus rift basin. The basin geometry influenced deformation style by controlling the initial thickness of the massive lower Argo salt. Generally, the lower Argo salt is thin or absent above shallow fault blocks and thick above deep fault blocks. The composition of the upper Argo Formation, which consists of halite and interbedded clastic sedimentary rocks, also influenced the deformation style in the basin. In parts of the basin, the halite of the upper Argo Formation is interbedded with numerous, thick shale beds. In other parts of the basin, however, the upper Argo Formation is predominantly halite with few shale beds, allowing it to behave ductilely like the massive lower Argo salt. The synrift Argo salt significantly influenced deformation during and after rifting. Growth beds in the upper Argo Formation associated with extensional fault-propagation folds reflect continued activity on basement-involved faults below the salt during its deposition. During the later phases of rifting, paired minibasins and salt walls/columns preferentially formed where the lower Argo salt was thick and/or where the upper Argo Formation had a high proportion of halite. Sediment loading near the northern border faults caused the underlying salt to move laterally, forming the minibasins, salt walls/columns, and possibly detached compressional structures. Immediately after rifting, shortening associated with basin inversion reactivated some basement-involved faults. Detached compressional structures (i.e., salt-cored folds) located to the south and far from minibasins likely resulted from this basement-involved shortening. It is unclear whether the detached compressional structures near the minibasins formed, at least in part, in response to the basement-involved shortening. The nature of the widespread unconformity during the Late Jurassic/Early Cretaceous remains unclear. However, additional postrift deformation during the Oligocene/Miocene again reactivated some basement-involved faults and shortened the buried salt walls/columns, producing domes in the sedimentary cover above them.M.S.Includes bibliographical referencesby Bari R.

Measurement of the D+/- production asymmetry in 7 TeV pp collisions
No full textThe asymmetry in the production cross-section \sigma of D+/- mesons, A_P = (\sigma(D+) - \sigma(D-))/(\sigma(D+) + \sigma(D-)), is measured in bins of pseudorapidity \eta and transverse momentum p_T within the acceptance of the LHCb detector. The result is obtained with a sample of D+ -> K_S pi+ decays corresponding to an integrated luminosity of 1.0 fb^-1, collected in pp collisions at a centre of mass energy of 7 TeV at the Large Hadron Collider. When integrated over the kinematic range 2.0 K_S pi+ decay is negligible. No significant dependence on \eta or p_T is observed
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

First observation of Bs → J/ψf0(980) decays
No full textUsing data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
Measurement of the inclusive φ cross-section in pp collisions at √s=7 TeV
No full textThe cross-section for inclusive φ meson production in pp collisions at a centre-of-mass energy of √s = 7 TeV has been measured with the LHCb detector at the Large Hadron Collider. The differential cross-section is measured as a function of the φ transverse momentum pT and rapidity y in the region 0.6< pT <5.0 GeV/c and 2.44< y <4.06. The cross-section for inclusive φ production in this kinematic range is σ(pp→φX)=1758±19(stat) +43−14(syst)±182(scale) μb, where the first systematic uncertainty depends on the pT and y region and the second is related to the overall scale. Predictions based on the Pythia 6.4 generator underestimate the cross-section
