    B Physics in the Next Millennium

    Full text link
    As we approach the turn of the century, the Standard Model is still consistent with all our experimental observations and the path to a more complete picture of the fundamental constituents and their interactions has yet to be clearly identified. Beauty flavored hadrons have provided crucial experimental information on several fundamental parameters of the Standard Model and may lead to one of the most challenging test of its validity and provide some clues on the path towards a more complete theory. Several experiments will try to explore this rich phenomenology in the next few years. Their physics goals and discovery potential will be compared.Comment: 11 pages, 4 Figures, Talk given at HQ98, Batavia, Il, October 199

    Recycling Parrondo games

    We consider a deterministic realization of Parrondo games and use periodic orbit theory to analyze their asymptotic behavior.Comment: 12 pages, 9 figure

    The Lepton-Number-Violating Decays of B+,D+B^+, D^+ and Ds+D_s^+ Mesons Induced by the Doubly Charged Higgs Boson

    Full text link
    The lepton-number-violating decays of B+,D+B^+, D^+ and Ds+D_s^+ mesons induced by the doubly charged Higgs boson have been studied. It is found that although the yielded results of the branch ratio are much smaller than the present limits from the data they are consistent with the previous conclusions calculated in the framwork of relativistic quark model where the processes happened via the light Majorana neutrinos.Comment: version to appear in PR

    Fractal diffusion coefficient from dynamical zeta functions

    Full text link
    Dynamical zeta functions provide a powerful method to analyze low dimensional dynamical systems when the underlying symbolic dynamics is under control. On the other hand even simple one dimensional maps can show an intricate structure of the grammar rules that may lead to a non smooth dependence of global observable on parameters changes. A paradigmatic example is the fractal diffusion coefficient arising in a simple piecewise linear one dimensional map of the real line. Using the Baladi-Ruelle generalization of the Milnor-Thurnston kneading determinant we provide the exact dynamical zeta function for such a map and compute the diffusion coefficient from its smallest zero.Comment: 8 pages, 2 figure
