    One-particle inclusive CP asymmetries in the decays of the type B -> D(*) X are considered in the framework of a QCD based method to calculate the rates for one-particle inclusive decays.Comment: Latex, 13 pages, 6 figures (eps).

    We present the first study of the vector (Wess-Zumino) current in τ → K π^− K^+ ν_τ decay using data collected with the CLEO III detector at the Cornell Electron Storage Ring. We determine the quantitative contributions to the decay width from the vector and axial vector currents. Within the framework of a model by Kühn and Mirkes, we identify the quantitative contributions to the total decay rate from the intermediate states ωπ, ρ^(')π, and K^∗ K

    Prospects for Direct CP Violaton in Exclusive and Inclusive Charmless B decays

    Within the Standard Model, CP rate asymmetries for BKπ+,0B\to K^-\pi^{+,0} could reach 10%. With strong final state phases, they could go up to 20--30%, even for Kˉ0π\bar K^0\pi^- mode which would have opposite sign. We can account for Kπ+K^-\pi^{+}, Kˉ0π\bar K^0\pi^- and ϕK\phi K rate data with new physics enhanced color dipole coupling and destructive interference. Asymmetries could reach 40--60% for KπK\pi and ϕK\phi K modes and are all of the same sign. We are unable to account for Kπ0K^-\pi^0 rate. Our inclusive study supports our exclusive results.Comment: Minor changes, correct a small bug in Fig. 1(b). Version to appear in Phys. Rev. Let

    Community Research Report Horton Housing

    A Community Research project was co-produced with community members who received training and support from a Leeds Beckett University researcher. Four people chose to become Community Researchers on this project: 3 Afghan men living in temporary hotel accommodation in Bradford and one British woman who volunteers with a housing association. They attended 3 training sessions on research, survey design, and research ethics. The Community Researchers created a survey with the Leeds Beckett researcher and then used the survey independently. The male Community Researchers spoke to other Afghan men and the female Community Researcher spoke to Afghan women. The women felt more comfortable answering as a group. The group had 5 weeks to collect information using the surveys. The Community and University Researchers analysed the information from the survey together and the findings are summarised in this report
