Hadronic decays
Hadronic decays and transitions are a key ingredient of hadronic physics. I
discuss how hadronic decays can be explored in lattice gauge theory and review
studies undertaken. I also discuss the impact of decays on masses and how
lattice studies can explore the nature of a hadronic state: namely whether it
is a molecular or quark-antiquark state. A brief discussion of lattice
exploration of pentaquark states is presented.Comment: 14 pages, plenary talk at Lattice 2005, Dublin, July 25-3
The Brontini of the world : a generic review of the tribe (Coleoptera: Silvanidae: Brontinae)
The genera of the tribe Brontini (Silvanidae: Brontinae) are reviewed. The tribe is considered here to be composed of 12 genera, Uleiota Latreille, Brontopriscus Sharp, and Dendrophagus Schönherr, plus nine new genera: Australodendrophagus, Australohyliota, Brontoliota, Dendrophagella, Macrohyliota, Megahyliota, Microhyliota, Parahyliota, and Protodendrophagus. Aplatamus Grouvelle is removed from the Brontini and placed in the Telephanini. Four new species are described: Protodendrophagus antipodes Thomas; Brontoliota indivisipennis Thomas; Brontoliota intermedius Thomas; and Brontoliota monteithi Thomas. Described species are assigned to genera with the following new combinations resulting: Australodendrophagus australis (Erichson); Australohyliota chilensis (Blanchard); Australohyliota macleayi (Olliff); Denrophagella capito (Pascoe); Macrohyliota truncatipennis (Heller); Macrohyliota bicolor Arrow; Macrohyliotagracilicornis (Arrow); Macrohyliota lucius (Pascoe); Macrohyliota militaris (Erichson); Macrohyliota spinicollis (Gory); Megahyliota feae (Grouvelle); Microhyliota integricollis (Fairmaire); Parahyliota africanus Grouvelle; Parahyliota alticola (Pal, Sen Gupta, and Crowson); Parahyliota atratus (Grouvelle); Parahyliota brevicollis (Arrow); Parahyliota cinamomeus (Fairmaire); Parahyliota costicollis (Reitter); Parahyliota fallax (Grouvelle); Parahyliota indicus (Arrow); Parahyliota pallidus (Arrow); Parahyliota puberulus (Reitter); Parahyliota serratus (Smith); Parahyliota serricollis (Candeze); Parahyliota siamensis (Arrow). Two new synonymies are proposed: Uleiota crenicollis Grouvelle (=Uleiota costicollis Grouvelle) and Uleiota texana Dajoz (=Uleiota dubius (Fabricius)). Uleiota truncatus Motschulsky, formerly treated as a subspecies of U. dubius (Fabricius), is elevated to a full species, new status
A review of New World Laemophloeus Dejean (Coleoptera: Laemophloeidae) : 1., species with antennal club of more than three antennomeres
Five Neotropical species of Laemophloeus Dejean (s. str.) (Coleoptera: Laemophloeidae) with antennal clubs of more than three antennomeres are reviewed: L. buenavista Thomas, n.sp.; L. concinnus Thomas, n.sp.; L. germaini Grouvelle; L. macrognathus Reitter; and L. sexarticulatus Kessel. Diagnoses, descriptions of the new species, illustrations, and a key are provided. Laemophloeus prominens Hetschko, proposed as a replacement name for Laemophloeus notabilis Kessel, is synonymized under L. germaini, new synonymy
The Mass Spectrum of a Static Adjoint Particle
The bound states of fermions in the adjoint representation are of interest in
supersymmetric models. We investigate the energy spectrum of the simplest --
the gluino-gluon bound states -- on several lattices in the quenched
approximation. We use a static approximation for the gluino propagator. We find
continuum limits of the splitting between the few lowest states, with the
energy difference between the two lowest states of  MeV.Comment: 3 pages, Latex, to appear Lattice 97 proceding
Conditional Probabilities of Multivariate Poisson Distributions
Multivariate Poisson distributions have numerous applications. Fast
computation of these distributions, holding constant a fixed set of linear
combinations of these variables, has been explored by Sontag and Zeilberger.
This elaborates on their work
Birds observed at Ghubrah Bowl, Saiq Plateau and Jabal Shams, Northern Oman; 19 March-26 April 2005 with comments on their status and population
The current study was part of a series of environment related studies of the Jabal Akhdar sponsored by the Sultan Qaboos University, Al Khoud, Sultanate of Oman. The present study aimed to establish the range, habitat, status and population of breeding species in the area, review the historical perspective and list migrant and visitor species noted during the survey
