Detailed Far-UV to Optical Analysis of Four [WR] Stars
W. L. F. Marcolino, D. J. Hillier, F. X. de Araujo +1
We present far-UV to optical analyses of four hydrogen deficient central stars of planetary nebulae: BD+303639, NGC 40, NGC 5315 and NGC 6905. Using the radiative transfer code CMF…
Secondary Beam Monitors for the NuMI Facility at FNAL
S. Kopp, M. Bishai, M. Dierckxsens +20
The Neutrinos at the Main Injector (NuMI) facility is a conventional neutrino beam which produces muon neutrinos by focusing a beam of mesons into a long evacuated decay volume. We…
Resummation of Large Endpoint Corrections to Color-Octet J/psi Photoproduction
Sean Fleming, Adam K. Leibovich, Thomas Mehen
An unresolved problem in J/psi phenomenology is a systematic understanding of the differential photoproduction cross section, dsigma/dz [gamma + p -> J/psi + X], where z= E_psi/E_g…
Detection of additional Wolf-Rayet stars in the starburst cluster Westerlund 1 with SOAR
J. H. Groh, A. Damineli, M. Teodoro +1
We report the detection of 3 additional Wolf-Rayet stars in the young cluster Westerlund 1. They were selected as emission-line star candidates based on 1 micron narrow-band imagin…
Nucleon-Meson Coupling Constants and Form Factors in the Quark Model
C. Downum, T. Barnes, J. R. Stone +1
We demonstrate the calculation of the coupling constants and form factors required by effective hadron lagrangians using the quark model. These relations follow from equating expre…
