1 0 Ja n 20 09 A Characterization On Potentially K 6 − C 4 - graphic Sequences ∗

For given a graphH , a graphic sequence π = (d1, d2, · · · , dn) is said to be potentially H-graphic if there exists a realization of π containing H as a subgraph. Let Km −H be the graph obtained from Km by removing the edges set E(H) where H is a subgraph of Km. In this paper, we characterize the potentially K6 − C4-graphic sequences. This characterization implies a theorem due to Hu and Lai [7].

Λ - Λ Interferometry in ( K − , K + ) Reactions at P ( K − ) = 1 . 8 GeV / c

We study (K−, K) reactions on nuclear targets (C and Be) at incident K− momentum of P (K−) =1.65 and 1.8 GeV/c by using the intranuclear cascade model combined with the correlation function technique. We compare the calculated results with two different sets of elementary mesonbaryon cross sections, but we cannot find significant differences in K spectra and ΛΛ invariant mass spectra. The calcu...

On the Rational Recursive Sequence X_{N+1}=ƔX_{N-K}+(AX_N+BX_{N-K})⁄(CX_N-DX_{N-K})

K&C Science Report – Phase 1

Using JERS-1 and PALSAR radar images provided by JAXA, we built regional and continental scale mosaics of Sahara that allowed to discover major geological features. The unique capability of L-band SAR to map subsurface structures in arid areas revealed several impact craters and paleo-rivers in

The in-medium modifications on the K − /K + ratio produced at GSI are studied. Particular attention is paid to the properties of antikaons, which determine the chemical potential and temperature at freeze-out conditions. Different approaches have been considered: non-interacting K − , on-shell self-energy and single-particle spectral density. We observe that the full off-shell approach to the s...
