Observation of eta_c^{prime} Production in gamma gamma Fusion at CLEO

D. M. Asner, CLEO Collaboration

We report on the observation of the eta_{c}^{prime}(2^{1}S_{0}), the radial excitation of eta_{c}(1^{1}S_{0}) ground state of charmonium, in the two-photon fusion reaction gamma ga…

A Chandra HETGS observation of the Narrow-line Seyfert 1 galaxy Ark 564

Chiho Matsumoto, Karen M. Leighly, Herman L. Marshall

We present results from a 50 ks observation of the narrow-line Seyfert 1 galaxy Ark 564 with the Chandra HETGS. The spectra above 2 keV are modeled by a power-law with a photon-ind…

Search for CP Violation in D^0--> K_S^0 pi^+pi^-

D. M. Asner, CLEO Collaboration

We report on a search for CP violation in the decay of D0 and D0B to Kshort pi+pi-. The data come from an integrated luminosity of 9.0 1/fb of e+e- collisions at sqrt(s) ~ 10 GeV r…

A Complete Sample of Soft X-ray Selected AGN: I. The Data

D. Grupe, B. J. Wills, K. M. Leighly +1

We present the optical spectra and simple statistical analysis for a complete sample of 110 soft X-ray selected AGN. About half of the sources are Narrow-Line Seyfert 1 galaxies (N…
