We remind the chiral doubling scenario [1,2] for hadrons built of heavy and light quarks. Then we recall the arguments why new states Ds(2317), Ds(2460), D0(2308) and D ′ 1(2427) should be viewed as chiral partners of Ds, D∗ s , D and D ∗, respectively. We summarize with the list of predictions based of chiral doubling scenario for other heavy-light hadrons. Chiral doublings of heavy-light hadr...
D0-branes are unstable in the presence of an R-R field strength background. A fuzzy twosphere is classically stable under such a background, this phenomenon being called the Myers effect. We analyze this effect from the viewpoint of tachyon condensation. It is explicitly shown that a fuzzy two-sphere is realized by the condensation of tachyons which appear from strings connecting different D0-b...
In this article, we consider the representation of prime powers by binary quadratic forms of discriminant D = −2q1 . . . qt where the product of primes q1 . . . qt ≡ 3 (mod 4), for instance if it is of special RichaudDegert type n2 ± 2 for odd n’s, n2 − 1 for even n’s. We consider all the ambiguous classes and Q( √|D0|), where D0 is the fundamental discriminant and we obtain a general criterion...
We study D-branes in SU(2) WZW model by means of the boundary state techniques. We realize the “fuzzy sphere” configuration of multiple D0-branes as the boundary state with the insertion of suitable Wilson line. By making use of the path-integral representation we show that this boundary state preserves the appropriate boundary conditions and leads to the Cardy state describing a spherical D2-b...
We study D-branes in the mirror pair N = 2 Liouville/supersymmetric SL(2,R)/U(1) coset superconformal field theories. We build D0, D1 and D2 branes, on the basis of the boundary state construction for the H 3 conformal field theory. We also construct D0-branes in an orbifold that rotates the angular direction of the cigar. We show how the poles of correlators associated to localized states and ...
In ee collisions using the CLEO detector we have studied the decay of the D to the final state K Sπ π with the initial flavor of the D tagged in charged D decay. We use the Dalitz technique to measure the resonant substructure in this final state and clearly observe ten different contributions by fitting for their amplitudes and relative phases. We observe a Kπ component which arises from doubl...
A theory of di erential characters is developed for manifolds with boundary. This is done from both the Cheeger-Simons and the deRham-Federer viewpoints. The central result of the paper is the formulation and proof of a Lefschetz-Pontrjagin Duality Theorem, which asserts that the pairing c IHk(X; @X) c IHn k 1(X) ! S1 given by ( ; ) 7! ( ) [X] induces isomorphisms D : c IHk(X; @X)! Hom1(c IHn k...
The conditional diameter Dν of a digraph G measures how far apart a pair of vertex sets V1 and V2 can be in such a way that the minimum out-degree and the minimum in-degree of the subdigraphs induced by V1 and V2, respectively, are at least ν. Thus, D0 is the standard diameter and D0 ≥ D1 ≥ . . . ≥ Dδ, where δ is the minimum degree. We prove that if Dν ≤ 2` − 3, where ` is a parameter related t...

Diffusion measurements have been made for 114In in Ga between 20° and 455 °C, and for 72Ga in In between the m.p. and 380 °C. Linear plots of D vs T describe the results about equally well as Arrhenius representations. The Arrhenius parameters are D0 = 2.1 • 104 cm2/s, @ = 1.64 kcal/mol for In in Ga, D0 = 2.4 • 10~ 4 cm2/'s, Q = 1.93 kcal/mol for Ga in In. Ga diffuses faster than In in both mat...
