Application of Ohio Post-Conviction Procedure - Effect of Prior Judgment On.; Coley v. Alvis
In the per curiam decision of Coley v. Alvis\u27 the United States Court of Appeals for the Sixth Circuit reversed an Ohio District Court decision dismissing Coley\u27s petition for habeas corpus for failure to exhaust his state remedies. The circuit Court remanded, stating that it would be futile for petitioner to attempt to void his conviction under the Ohio post-conviction statute because of the narrow limits placed on it by the state courts and that there was consequently no longer any effective state remedy. Since the grounds that petitioner set forth to sustain his writ did not fall within any of the enumerated exceptions recognized by Ohio Supreme Court decisions, the court held that petitioner should be allowed to seek relief in the federal court without appealing the ruling on his writ to the Supreme Court of Ohio

Study of and decays and determination of the CKM angle
We report a study of the suppressed and favored
decays, where the neutral meson is detected
through its decays to the and CP-even and
final states. The measurement is carried out using a proton-proton
collision data sample collected by the LHCb experiment, corresponding to an
integrated luminosity of 3.0~fb. We observe the first significant
signals in the CP-even final states of the meson for both the suppressed
and favored modes, as well as
in the doubly Cabibbo-suppressed final state of the decay. Evidence for the ADS suppressed decay , with , is also presented. From the observed
yields in the , and their
charge conjugate decay modes, we measure the value of the weak phase to be
. This is one of the most precise
single-measurement determinations of to date.Comment: 22 pages, 9 figures; All figures and tables, along with any

A study of violation in () with the modes , and
An analysis of the decays of and is presented in which the meson is reconstructed in
the three-body final states , and . Using data from LHCb corresponding to an integrated luminosity of
3.0 fb of collisions, measurements of several observables are
performed. First observations are obtained of the suppressed ADS decay and the quasi-GLW decay . The results are interpreted in the
context of the unitarity triangle angle and related parameters
Observation of the decay
The first observation of the decay is reported. The
study is based on a sample of proton-proton collisions corresponding to
of integrated luminosity collected with the LHCb detector. The
significance of the signal is standard deviations. The branching fraction
is measured to be , where the third uncertainty comes from the
branching fraction that is used as a normalisation.
In addition, the charge asymmetries of and
, which are control channels, are measured to be and , respectively. All results are consistent with
theoretical expectations
Amplitude analysis of decays
The Dalitz plot distribution of decays
is studied using a data sample corresponding to of
collision data recorded by the LHCb experiment during 2011 and 2012. The data
are described by an amplitude model that contains contributions from
intermediate , , and
resonances. The model also contains components to describe broad structures,
including the and resonances, in the
S-wave and the S- and P-waves. The masses and widths of the
and resonances are measured, as are the complex
amplitudes and fit fractions for all components included in the amplitude
model. The model obtained will be an integral part of a future determination of
the angle of the CKM quark mixing matrix using decays.Comment: 33 pages, 12 figures; updated for publicatio
Measurement of the branching fraction ratio
Using collision data collected by LHCb at center-of-mass energies
= 7 TeV and 8 TeV, corresponding to an integrated luminosity of 3
fb, the ratio of the branching fraction of the decay relative to that of the
decay is measured to be 0.268 0.032 (stat) 0.007 (syst) 0.006
(BF). The first uncertainty is statistical, the second is systematic, and the
third is due to the uncertainties on the branching fractions of the and decays. This
measurement is consistent with the previous LHCb result, and the statistical
uncertainty is halved.Comment: 17 pages including author list, 2 figure
