Measurement of Masses and Widths of Excited

Using data from the FOCUS experiment we analyze the D+π− and D0π+ invariant mass distributions. We measure the D∗0 2 mass MD∗0 2 = (2464.5 ± 1.1 ± 1.9)MeV/c2 and width ΓD∗0 2 = (38.7±5.3±2.9)MeV/c2, and theD 2 massMD∗+ 2 = (2467.6± 1.5± 0.76)MeV/c2 and width ΓD∗+ 2 = (34.1± 6.5± 4.2)MeV/c2. We find evidence for broad structures over background in both the neutral and charged final state. If eac...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
