A Large-N Reduced Model as Superstring
N. Ishibashi, H. Kawai, Y. Kitazawa +1
A matrix model which has the manifest ten-dimensional N=2 super Poincare invariance is proposed. Interactions between BPS-saturated states are analyzed to show that massless spectr…
Probing nonstandard bosonic interactions via W-boson pair production at lepton colliders
K. Hagiwara, T. Hatsukano, S. Ishihara +1
The process e+e- --> W+W- provides a valuable laboratory to test the Standard Model (SM) and to search for new physics. The most general helicity amplitudes for this process requir…
The Pion Decay Constants and the Rho-Meson Mass at Finite Temperature in the Hidden Local Symmetry
Masayasu Harada, Akihiro Shibata
We study the temperature dependence of the pion decay constant and rho-meson mass in the hidden local symmetry model at one loop. Using the standard imaginary time formalism, we in…
Associate Production: A Clean Probe of Unpolarized and Polarized Gluon Densities
C. S. Kim
Color-octet contributions to the associate production are found to be negligible, compared to the ordinary color-singlet contribution. Within the color-singlet model the $J…
Numerical analysis of renormalon technique in quantum mechanics
A. A. Penin, A. A. Pivovarov
We discuss the ways of extracting a low energy scale of an underlying theory using high energy scattering data. Within an exactly solvable model of quantum mechanics we analyze a t…
Scaling Behavior in 4D Simplicial Quantum Gravity
H. S. Egawa, T. Hotta, T. Izubuchi +2
Scaling relations in four-dimensional simplicial quantum gravity are proposed using the concept of the geodesic distance. Based on the analogy of a loop length distribution in the…
Thermodynamic properties of spontaneous magnetization in Chern-Simons QED_3
Shinya Kanemura, Takao Matsushita
The spontaneous magnetization in Chern-Simons QED_3 is discussed in a finite temperature system. The thermodynamical potential is analyzed within the weak field approximation and i…
Theoretical uncertainties for weak decays: higher dimension operators
A. A. Pivovarov
A brief review of recent results on computing contributions of higher dimension operators to weak effective hamiltonians for light quarks is presented.
Color-Octet Contributions in the Associate J/psi+gamma Hadroproduction
C. S. Kim, Jungil Lee, H. S. Song
Color-octet contributions to the associate J/psi+gamma hadroproduction are studied in detail, and found to be negligible, compared to the ordinary color-singlet contribution. Withi…
An Analysis of ππ-Scattering Phase Shift and Existence of σ(555) particle
S. Ishida, M. Y. Ishida, H. Takahashi +3
In most of the Nambu:Jona-Lasinio(NJL)-type models, realizing the hidden chiral symmetry, the existence of a scalar particle σis needed with a mass m_σ=2 m_q, as a partner of the N…
Virtual SUSY Threshold Effects and CDF large Anomaly
C. S. Kim, S. Alam
Recent CDF data of the inclusive jet cross section shows threshold-like structured deviation, around transverse momentum GeV. If this data is real, not…
Further Analysis on σ-particle Properties
Shin Ishida, Taku Ishida, Muneyuki Ishida +2
In a previous work, we have reanalyzed the I=0 S-wave ππ-scattering phase-shift through a new method of Interfering Breit-Wigner amplitudes, and have shown the existence of a light…

Toru Goto, Yasuhiro Okada, Yasuhiro Shimizu +1
The process is studied in the minimal supergravity model in detail. Taking account of the long distance contributions from the resonances,…
Particle-Particle-String Vertex
Nobuyuki Ishibashi
We study a theory of particles interacting with strings. Considering such a theory for Type IIA superstring will give some clue about M-theory. As a first step toward such a theory…

We have used 106 pb^-1 of data collected in proton-antiproton collisions at sqrt(s)=1.8 TeV by the Collider Detector at Fermilab to measure jet angular distributions in events with…
Scaling Structures in Four-dimensional Simplicial Gravity
H. S. Egawa, T. Hotta, T. Izubuchi +2
Four-dimensional(4D) spacetime structures are investigated using the concept of the geodesic distance in the simplicial quantum gravity. On the analogy of the loop length distribut…

H. Kawai, N. Tsuda, T. Yukawa
A method of defining the complex structure(moduli) for dynamically triangulated(DT) surfaces with torus topology is proposed. Distribution of the moduli parameter is measured numer…
