CP Violation and Strong Phases from Penguins in B±→VV\bf B^{\pm}\rightarrow VV Decays

We calculate direct CP-violating observables in charged $B\to VV$ decays arising from the interference of amplitudes with different strong and CKM phases. The perturbative strong phases develop at order $\alpha_s$ from absorptive parts of one-loop matrix elements of the next-to-leading logarithm corrected effective Hamiltonian. CPT constraints are maintained. Based on this model, we find that partial rate asymmetries between charge conjugate $B^{\pm}$ decays can be as high as 15-30\% for certain channels with branching ratios in the $10^{-6}$ range. The small values of the coefficients of angular correlations, which we calculated previously to be of order $10^{-2}$, are not significantly degraded by the strong phases. The charge asymmetries of rates and angular distributions would provide unambiguous evidence for direct CP violation.Comment: 24 pages, 3 figures (upon request), LaTeX, preprint DESY 93-19

Interview of Gerard Francis Molyneaux F.S.C.

Brother Gerry was born in 1935 to John and Anne, youngest of nine children, with four boys and four girls in Upper Darby, PA. His father was a mason specializing in marble, which is has been a business in the family for five generations carried on by his brother Jim, older by 5 years, while his mother was a stay at home mom. For primary education Br. Gerry attended St. Philomena\u27s in Lansdowne graduating in 1949, then attending West Catholic graduating in 1953. Inspired by the Christian Brothers who taught him, after a summer of consideration by the request of his parents Br. Gerry entered into the Christian Brothers. As every Brother begins, Br. Gerry went to Ammendale, MD where the head quarters for the Christian Brother in the region is. After spending one year, and some days due to a farming injury of being spliced open by root shears, Br. Gerry then went to live in a Christian Brother community in Elkins Park, while he attended La Salle University in February 1955. He graduated in June of 1958, with a BA in English and a MA in Theology

Direct CP Violation Asymmetries in Exclusive B Decays in a Bethe-Salpeter Approach

CP asymmetry in some exclusive decays of charged B meson are calculated in a Bethe-Salpeter approach. Hadronic final state interactions are ignored. Complex decay amplitudes are assumed to arise entirely from perturbative quark-antiquark loops. Calculations are done both with and without the gluon quark-antiquark vacuum polarization loops. The effects of neglecting the imaginary parts arising from the diagonal quark-antiquark loops are also studied.Comment: 15 pages, Latex, 2 eps-figures. Minor revisions. To be published in Phys.Lett.

T-Violating Triple-Product Correlations in Charmless Lambda_b Decays

Using factorization, we compute, within the standard model, the T-violating triple-product correlations in the charmless decays Lambda_b -> F_1 F_2, where F_1 is a light spin-1/2 baryon and F_2 is a pseudoscalar (P) or vector (V) meson. We find a large triple-product asymmetry of 18% for the decay Lambda_b -> p K^-. However, for other classes of Lambda_b -> F_1 P decays, the asymmetry is found to be at most at the percent level. For Lambda_b -> F_1 V decays, we find that all triple-product asymmetries are small (at most O(1%)) for a transversely-polarized V, and are even smaller for longitudinal polarization. Our estimates of the nonfactorizable contributions to these decays show them to be negligible, and we describe ways of testing this.Comment: 15 pages, LaTeX, no figure

Two body decays of the bb-quark: Applications to direct CP violation, searches for electro-weak penguins and new physics

A systematic experimental search for two-body hadronic decays of the b-quark of the type b to quark + meson is proposed. These reactions have a well defined experimental signature and they should be theoretically cleaner compared to exclusive decays. Many modes have appreciable branching ratios and partial rate asymmetries may also be quite large (about 8-50%) in several of them. In a few cases electroweak penguins appear to be dominant and may be measurable. CP violating triple correlation asymmetries provide a clean test of the Standard Model.Comment: 12 pages 1 figure 1 tabl

An electrostatic elliptical mirror for neutral polar molecules

Focusing optics for neutral molecules finds application in shaping and steering molecular beams. Here we present an electrostatic elliptical mirror for polar molecules consisting of an array of microstructured gold electrodes deposited on a glass substrate. Alternating positive and negative voltages applied to the electrodes create a repulsive potential for molecules in low-field-seeking states. The equipotential lines are parallel to the substrate surface, which is bent in an elliptical shape. The mirror is characterized by focusing a beam of metastable CO molecules and the results are compared to the outcome of trajectory simulations.Comment: 5 pages, 4 figure
