We study a geometric variational problem arising from modeling two-dimensional charged drops of perfectly conducting liquid in the presence an external potential. characterize semicontinuous envelope energy terms parameter measuring relative strength Coulomb interaction. As consequence, when potential is confining and repulsion below critical value, we show existence regularity estimates for vo...

Interactions of cationic tetrakis (N,N´,N´´,N´´´-tetramethyltetra-3,4-pyridinoporphyrazinatocobalt(II) (Co(tmtppa)) with synthetic polynucleotides, poly(A-T), poly(G-C) and calf thymus DNA have been characterized in 5 mM phosphate buffer, pH 7.2, by optical absorption and fluorescence spectroscopy. The appearance of hypochromicity effect and the red shift in UV-Vis spectrum of porphyrazine was ...

From the early days of quantum mechanics, it has long been expected that the greater the quantum number for a certain degree of freedom (corresponding to a greater number of nodes in the corresponding wave function), the better the semiclassical approximation [1]. This expectation, which is often referred to as Bohr’s correspondence principle, has persisted despite a lack of rigorous proof for ...

Recent results for B meson decay constants with NRQCD b-quarks and clover light quarks are discussed. Perturbative matching factors through O(α/M) are now available and incorporated into the analyses. An O(α a) improvement term to the heavy-light axial current is identified and included. The slope of fP S √ MP S versus 1/MP S is significantly reduced by these corrections.

New physics effects on the B 0 − ¯ B 0 mixing and B-decay amplitudes are discussed. By a combined analysis, the models of new physics can be partially distinguished. It is emphasized that the extraction of unitarity angles β and γ through rare decay K → πν˜ν and charged B decay B ± → DK ± respectively is not likely to be affected by new physics. Such an observation could be used to distinguish ...

With a sample of about 384 million BB pairs recorded with the BABAR detector, we search for the flavorchanging charged current transition B± → τ±ν and perform an amplitude analysis of the effective flavorchanging neutral current transition B± → φ(1020)K∗(892)± . We also extend our search for other K∗ final states in the decay B → φ(1020)K∗0 with a large K∗0 → K+π− invariant mass. Two samples of...
