Plans for the LIGO-TAMA Joint Search for Gravitational Wave Bursts
Patrick J. Sutton, Masaki Ando, Patrick Brady +18
We describe the plans for a joint search for unmodelled gravitational wave bursts being carried out by the LIGO and TAMA collaborations using data collected during February-April 2…
High-K Precession modes: Axially symmetric limit of wobbling motion
Yoshifumi R. Shimizu, Masayuki Matsuzaki, Kenichi Matsuyanagi
The rotational band built on the high-K multi-quasiparticle state can be interpreted as a multi-phonon band of the precession mode, which represents the precessional rotation about…
Fuzzy Torus in Matrix Model
Subrata Bal, Masanori Hanada, Hikaru Kawai +1
We have calculated the free energy up to two loop to compare T^2 with T^4 in IIB matrix model. It turns out that T^2 has smaller free energy than T^4. We have also discussed the ge…
Heat kernel coefficients for compact fuzzy spaces
Naoki Sasakura
I discuss the trace of a heat kernel Tr[e^(-tA)] for compact fuzzy spaces. In continuum theory its asymptotic expansion for t -> +0 provides geometric quantities, and therefore may…
Effects of rotation on the revival of a stalled shock in supernova explosions
T. Yamasaki, S. Yamada
In order to infer the effects of rotation on the revival of a stalled shock in supernova explosions, we investigated steady accretion flows with a standing shock. We first obtained…
Measurement of the analyzing power of proton-carbon elastic scattering in the CNI region at RHIC
O. Jinnouchi, I. G. Alekseev, A. Bravar +11
The single transverse spin asymmetry, A_N, of the p-carbon elastic scattering process in the Coulomb Nuclear Interference (CNI) region was measured using an ultra thin carbon targe…
Democratic mass matrices induced by strong gauge dynamics and large mixing angles for leptons
Tatsuo Kobayashi, Hiroaki Shirano, Haruhiko Terao
We consider dynamical realization of the democratic type Yukawa coupling matrices as the Pendelton-Ross infrared fixed points.?Such fixed points of the Yukawa couplings become poss…
Damped Lyman alpha Absorbing Galaxies At Low Redshifts z<1 From Hierarchical Galaxy Formation Models
Katsuya Okoshi, Masahiro Nagashima
We investigate Damped Ly-alpha absorbing galaxies (DLA galaxies) at low redshifts z<1 in the hierarchical structure formation scenario to clarify the nature of DLA galaxies because…
Role of Large Gluonic Excitation Energy for Narrow Width of Penta-Quark Baryons in QCD String Theory
Hideo Suganuma, Fumiko Okiharu, Toru T. Takahashi +1
We study the narrow decay width of low-lying penta-quark baryons in the QCD string theoryin terms of gluonic excitations. In the QCD string theory, the penta-quark baryon decays vi…
Narrow Width of Penta-Quark Baryons in QCD String Theory
Hideo Suganuma, Hiroko Ichie, Fumiko Okiharu +1
Using the QCD string theory, we investigate the physical reason of the narrow width of penta-quark baryons in terms of the large gluonic-excitation energy. In the QCD string theory…
Anisotropic lattice with nonperturbative accuracy
Hideo Matsufuru, Hidenori Fukaya, Masanori Okawa +2
We determine the nonperturbative anisotropic parameter of the gauge action in the quenched approximation with less than 1% accuracy using the Sommer scale measured by the Lüscher-W…
Discovery of a Large Scale Clumpy Structure around the Lynx Supercluster at z~1.27
Fumiaki Nakata, Tadayuki Kodama, Kazuhiro Shimasaku +12
We report the discovery of a probable large scale structure composed of many galaxy clumps around the known twin clusters at z=1.26 and z=1.27 in the Lynx region. Our analysis is b…
Collective Paths Connecting the Oblate and Prolate Shapes in 68Se and 72Kr Suggested by the Adiabatic Self-Consistent Collective Coordinate Method
M. Kobayasi, T. Nakatsukasa, M. Matsuo +1
By means of the adiabatic self-consistent collective coordinate method and the pairing-plus-quadrupole interaction, we have obtained the self-consistent collective path connecting…
Construction of Supergravity Backgrounds with a Dilaton Field
Noriko Nakayama, Katsuyuki Sugiyama
A new class of non-compact Kahler backgrounds accompanied by a non-constant dilaton field is constructed as a supergravity solution. It is interpreted as a complex line bundle over…
Nobeyama Millimeter Array Observations of GRB 030329: a Decay of Afterglow with Bumps and Molecular Gas in the Host Galaxy
K. Kohno, T. Tosaki, T. Okuda +12
Nobeyama Millimeter Array was used to observe millimeter-wave afterglow of GRB 030329 at 93 GHz and 141 GHz from 2003 April 6 to 2003 May 30. A sensitive search for CO(J=1-0) emiss…
Chandra Observation of the Starburst Galaxy NGC 2146
Tatsuya Inui, Hironori Matsumoto, Takeshi Go Tsuru +4
We present six monitoring observations of the starburst galaxy NGC 2146 using the Chandra X-ray Observatory. We have detected 67 point sources in the 8'.7 x 8'.7 field of view of t…

E. Czuchry, J. Jezierski, J. Kijowski
Hamiltonian dynamics of gravitational field contained in a spacetime region with boundary being a null-like hypersurface (a wave front) is discussed. Complete Hamiltonian formu…
