    Lessons from Recent Measurements of D-\bar D Mixing

    Full text link
    An impressive progress in measurements of the D-\bar D mixing parameters has been made in recent years. We explore the implications of these measurements to models of new physics, especially in view of recent upper bounds on the amount of CP violation. We update the constraints on non-renormalizable four-quark operators. We show that the experiments are close to probing minimally flavor violating models with large tan beta. The data challenge models with a scale of order TeV where the flavor violation in the down sector is suppressed by alignment and, in particular, certain classes of supersymmetric models and of warped extra dimension models.Comment: 20 pages, 1 figure.

    The Forgotten History: Textbook Controversy and Sino-Japanese Relations

    History plays an important role in shaping the relations between Japan and China. Because Japan�s military expansionism during 1931-1945 has left a deep scar in the memories of the Chinese population, the issue of history remains at the core of Sino-Japanese diplomacy. Since the 1980s, the Chinese government has consistently accused the Japanese government of revising and obscuring Japan�s wartime history, notably that of the Japanese military aggression in China during 1931-1945. China�s reaction against the Japanese government�s whitewashing of history demonstrates the fear that, by rendering Japanese youths oblivious of their nation�s militarist past, Japan may repeat its past. While diplomatic negotiations to improve Sino-Japanese relations have taken place, disagreement over historical interpretation continues to fuel the discontent between the two countries. To better understand the dynamics of the Sino-Japanese relations, the research investigates the origins and nature of the textbook controversy by discussing how the controversy came about and how each government responded to the issue. In addition, the analysis of ultranationalist movement in Japan allows us to understand the public reaction to the controversy as well as its political repercussions. I also explore the Franco-German case of postwar reconciliation and development of preventive institutions. By comparing the postwar experience of China and Japan to that of Europe, we can gain an insight about the creative ways of constructing a common history between historically hostile nations. Finally, the assessment of Japanese leadership since 2000 enables us to evaluate the future development surrounding the problem of history and its impact on bilateral relations

    Interference Between Cabibbo Allowed and Doubly Forbidden Transitions in D\ra K_{S,L} + \pi 's Decays

    Both Cabibbo allowed and doubly forbidden transitions contribute coherently to DKS,L+πsD\rightarrow K_{S,L}+\pi 's decays. This leads to several intriguing and even quantitatively significant consequences, among them: (i) A difference between Γ(D+KSπ+)\Gamma (D^+\rightarrow K_S \pi ^+) and Γ(D+KLπ+)\Gamma (D^+\rightarrow K_L \pi ^+) and between Γ(D0KSπ0)\Gamma (D^0\rightarrow K_S \pi ^0) and Γ(D0KLπ0)\Gamma (D^0\rightarrow K_L \pi ^0) of roughly 10\% ; similarly Γ(D+[KSπ0]Kπ+)14Γ(D+[Kπ+]Kπ+)\Gamma (D^+\rightarrow [K_S\pi ^0]_{K^*} \pi ^+) \neq \frac{1}{4}\Gamma (D^+\rightarrow [K^-\pi ^+]_{K^*} \pi ^+), and more generally Γ(DKˉ0+πs)2Γ(DKS+πs)\Gamma (D\rightarrow \bar K^0+\pi 's) \neq 2\Gamma (D\rightarrow K_S+\pi 's). (ii) A change in the relative phase between the isospin 3/2 and 1/2 amplitudes as extracted from the observed branching ratios for D+KSπ+D^+\rightarrow K_S\pi ^+, D0KSπ0,Kπ+D^0\rightarrow K_S\pi ^0 ,\, K^-\pi ^+. (iii) If New Physics intervenes to provide the required {\em weak} phase, then CP asymmetries of up to a few per cent can arise in D+KSπ+D^+\rightarrow K_S\pi ^+ vs. DKSπD^-\rightarrow K_S\pi ^-, D0KSπ0D^0\rightarrow K_S\pi ^0 vs. Dˉ0KSπ0\bar D^0\rightarrow K_S\pi ^0, D+[KSπ0]Kπ+D^+\rightarrow [K_S\pi ^0]_{K^*}\pi ^+ vs. D[KSπ0]KπD^-\rightarrow [K_S\pi ^0]_{K^*}\pi ^-, etc.; an asymmetry of the same size, but opposite in sign occurs when the KSK_S is replaced by a KLK_L in the final state.Comment: 6 pages, latex, no figure

    Recent direct measurement of the Top quark mass and quasi-infrared fixed point

    Get PDF
    We note that the recent direct measurement of the top quark mass at 173.3±5.6(stat)±6.2(syst)173.3 \pm 5.6 (stat) \pm 6.2 (syst) by D0 collaboration severely constrains the theoretically attractive infra-red fixed point scenario of the top quark Yukawa coupling in supersymmetric GUTs. For one-step unified models the above mentioned measurement bounds the arbitrary but experimentally determinable parameter tanβ\tan \beta to the range 1.3tanβ2.11.3 \le \tan \beta \le 2.1. Further crunch on the top quark mass may determine tanβ\tan \beta even more accurately within the fixed point scenario. On the other hand an experimental value of tanβ>2.1\tan \beta > 2.1 will rule out the fixed point scenario bounding ht2(MX)/4πh^2_t(M_X)/4 \pi to 0.022 from above.Comment: 7 pages, Latex with epsf style, 1 figure, captions.st

    Phenomenological Consequences of Right-handed Down Squark Mixings

    Get PDF
    The mixings of dRd_R quarks, hidden from view in Standard Model (SM), are naturally the largest if one has an Abelian flavor symmetry. With supersymmetry (SUSY) their effects can surface via d~R\tilde d_R squark loops. Squark and gluino masses are at TeV scale, but they can still induce effects comparable to SM in BdB_d (or BsB_s) mixings, while D0D^0 mixing could be close to recent hints from data. In general, CP phases would be different from SM, as may be indicated by recent B Factory data. Presence of non-standard soft SUSY breakings with large tanβ\tan\beta could enhance bdγb\to d\gamma (or sγs\gamma) transitions.Comment: Version to appear in Phys. Rev. Let
