Measurement Of |V_ub| From Inclusive Charmless Semileptonic B Decays

We present the partial branching fraction for inclusive charmless semileptonic B decays and the corresponding value of the CKM matrix element |Vub|, using a multivariate analysis method to access ~90% of the B -> Xu l nu phase space. This approach dramatically reduces the theoretical uncertainties from the b-quark mass and non-perturbative QCD compared to all previous inclusive measurements. The results are based on a sample of 657 million B -Bbar pairs collected with the Belle detector. We find that Delta BR(B -> Xu l nu; p^*B_l>1.0 GeV/c=1.963 x (1 +/- 0.088(stat.) +/- 0.081(sys.)) x 10^-3. Corresponding values of |Vub| are extracted using several theoretical calculations.Comment: 9 pages, 1 figure, 2 tables. Published in PR

Charmless two-body B decays: A global analysis with QCD factorization

In this paper, we perform a global analysis of $B \to PP$ and $PV$ decays with the QCD factorization approach. It is encouraging to observe that the predictions of QCD factorization are in good agreement with experiment. The best fit $\gamma$ is around $79^\circ$. The penguin-to-tree ratio $|P_{\pi \pi}/T_{\pi \pi}|$ of $\pi^+ \pi^-$ decays is preferred to be larger than 0.3. We also show the confidence levels for some interesting channels: $B^0 \to \pi^0 \pi^0$, $K^+ K^-$ and $B^+ \to \omega \pi^+$, $\omega K^+$. For $B \to \pi K^\ast$ decays, they are expected to have smaller branching ratios with more precise measurements.Comment: 20 pages, 4 figures, version to appear in Phys. Rev.

The Physics of Hadronic Tau Decays

Hadronic tau decays represent a clean laboratory for the precise study of quantum chromodynamics (QCD). Observables (sum rules) based on the spectral functions of hadronic tau decays can be related to QCD quark-level calculations to determine fundamental quantities like the strong coupling constant, parameters of the chiral Lagrangian, |V_us|, the mass of the strange quark, and to simultaneously test the concept of quark-hadron duality. Using the best available measurements and a revisited analysis of the theoretical framework, the value alpha_s(m_tau) = 0.345 +- 0.004[exp] +- 0.009[theo] is obtained. Taken together with the determination of alpha_s(m_Z) from the global electroweak fit, this result leads to the most accurate test of asymptotic freedom: the value of the logarithmic slope of 1/alpha_s(s) is found to agree with QCD at a precision of 4%. In another approach, the tau spectral functions can be used to determine hadronic quantities that, due to the nonperturbative nature of long-distance QCD, cannot be computed from first principles. An example for this is the contribution from hadronic vacuum polarization to loop-dominated processes like the anomalous magnetic moment of the muon. This article reviews the measurements of nonstrange and strange tau spectral functions and their phenomenological applications.Comment: 89 pages, 32 figures; final version accepted for publication by Reviews of Modern Physic

Assessing the Conditions for Multilateral Interventions or Non-Interventions: Intervention and Non-Intervention in the Asia Pacific Region

The focus of this thesis has been on the identification of the primary conditions that attract or deter multilateral interventions into internal conflicts in the Asia Pacific region. This thesis develops a framework which is applied to four cases of internal conflict to see what roles twenty-two structural and perceptual conditions have played in determining why multilateral intervention was initiated in two of the cases, and why multilateral intervention failed to be initiated in the other two cases. The research found that multilateral organizations will accept risks and costs associated with intervention if certain structural and perceptual conditions make intervention an attractive option. These conditions are, a favourable or significant international environment or international event(s), the consent of a sovereign state (even if it is induced), sustained and critical regional and international media coverage, a complete collapse of the state in conflict tainting it with the term 'failed state', a high probability of success, potential economic benefits, a humanitarian crisis (in respect of Unregulated Population Movements and genocide/politicide), the possibility of a clear exit strategy, and a self-interested Member State who can greatly subsidize an intervention. Multilateral non-interventions, on the contrary, are driven by a combination of a lack of sustained and critically analyzed media coverage on conflict issues and consequences, generally positive tactics and strategies adopted by disputants, conflicts of a long duration, the international environment, economic factors unfavourable to intervention, resistance levels to intervention or a failure to call for intervention, lack of any clear exit points, and an escalation phase. The importance of these conditions suggest that multilateral organizations are reluctant to take risks and costs when political will, for the collective and self, are not provoked. Consequently, particular structural and perceptual conditions trigger or influence political will. The analysis of four case studies (East Timor, Solomon Islands, Philippines (Moros), and West Papua) concludes that multilateral interventions will be the exception to the rule in the foreseeable future given the obvious selection bias evident in these policies, and the project questions the ad hoc determinants of current multilateral intervention policies

Physics at the e+ e- Linear Collider

A comprehensive review of physics at an e+e- Linear Collider in the energy range of sqrt{s}=92 GeV--3 TeV is presented in view of recent and expected LHC results, experiments from low energy as well as astroparticle physics.The report focuses in particular on Higgs boson, Top quark and electroweak precision physics, but also discusses several models of beyond the Standard Model physics such as Supersymmetry, little Higgs models and extra gauge bosons. The connection to cosmology has been analyzed as well.Comment: 179 pages, plots and references updated, version to be published at EPJ

Hadron Spectroscopy: Theory and Experiment

Many new results on hadron spectra have been appearing in the past few years thanks to improved experimental techniques and searches in new channels. New theoretical techniques including refined methods of lattice QCD have kept pace with these developments. Much has been learned about states made of both light (u, d, and s) and heavy (c, b) quarks. The present review treats light-quark mesons, glueballs, hybrids, particles with a single c or b quark, charmonium, and bottomonium states. Some prospects for further study are noted.Comment: 29 pages, 9 figures, to be published in Journal of Physics G. Further updating of reference

Problems with extracting ms from flavor breaking in hadronic tau decays

A numerical error is pointed out in the existing expression for the O(αs²) longitudinal component of the squared-mass (D=2) contribution to the hadronic τ decay rate. The corrected version is found to be such that, to O(αs²), each term in the resulting series is larger than the previous one, hence ruling out the direct use of flavor breaking in hadronic τ decays as a means of extracting the strange quark mass. An alternate approach, in which one uses the model spectral functions previously developed for the strangeness-changing scalar channel (and employed in alternate sum rule analyses of ms) as input to the τ decay analysis, is shown to provide mutual consistency checks for the two different methods. The results for ms implied by τ decay data and the existing model spectral function are also presented.Kim Maltma
