Lessons from Recent Measurements of D-\bar D Mixing
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. Added references, minor corrections and

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 decays. This leads to several intriguing and
even quantitatively significant consequences, among them: (i) A difference
between and and between and of roughly 10\% ; similarly , and more generally . (ii) A
change in the relative phase between the isospin 3/2 and 1/2 amplitudes as
extracted from the observed branching ratios for ,
. (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 vs. ,
vs. , vs. , etc.; an
asymmetry of the same size, but opposite in sign occurs when the is
replaced by a in the final state.Comment: 6 pages, latex, no figure
Recent direct measurement of the Top quark mass and quasi-infrared fixed point
We note that the recent direct measurement of the top quark mass at 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 to the range . Further
crunch on the top quark mass may determine even more accurately
within the fixed point scenario. On the other hand an experimental value of
will rule out the fixed point scenario bounding
to 0.022 from above.Comment: 7 pages, Latex with epsf style, 1 figure, captions.st
Phenomenological Consequences of Right-handed Down Squark Mixings
The mixings of 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 squark loops. Squark and
gluino masses are at TeV scale, but they can still induce effects comparable to
SM in (or ) mixings, while 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 could enhance (or )
transitions.Comment: Version to appear in Phys. Rev. Let
