Phase Structure of the Gauged Yukawa Model
Kei-ichi Kondo, Akihiro Shibata, Masaharu Tanabashi +1
Based on the ladder Schwinger-Dyson equation, we investigate phase struc- ture of the gauged Yukawa model possessing a global symmetry and an unbroken (vec…
String Field Theory of Noncritical Strings
N. Ishibashi, H. Kawai
We construct a string field Hamiltonian for a noncritical string theory with the continuum limit of the Ising model or its generalization as the matter theory on the worldsheet. It…
Lattice QCD Calculation of Hadron Scattering Lengths
Y. Kuramashi, M. Fukugita, H. Mino +2
Method of calculating hadron multi-point functions and disconnected quark loop contributions which are not readily accessible through conventional techniques is proposed. Results a…

M. Drees, M. M. Nojiri
In this paper we discuss possible signatures for the production of scalar \stst\ (stoponium) bound states \sigst\ at hadron colliders, where \st\ is the lighter scalar top eigensta…
Two-Dimensional Quantum Gravity in Temporal Gauge
M. Fukuma, N. Ishibashi, H. Kawai +1
We propose a new type of gauge in two-dimensional quantum gravity. We investigate pure gravity in this gauge, and find that the system reduces to quantum mechanics of loop length $…
Monte Carlo Approach to Radiative Corrections in Bhabha Scattering
J. Fujimoto, Y. Shimizu, T. Munehisa
A new Monte Carlo model is proposed for radiative corrections to Bhabha scattering by extending QEDPS developed for multi-photon emission in muon pair production in annihi…
Sea Quark Effects on the Strong Coupling Constant
T. Onogi, S. Aoki, M. Fukugita +5
We present results showing that the strong coupling constant measured in two-flavor full QCD with dynamical Kogut-Susskind quarks at exhibit a 15\% increase due to sea quar…
Finite-Size Effect of Hadron Masses with Kogut-Susskind Quarks
S. Aoki, T. Umemura, M. Fukugita +4
We present numerical results and their analyses of finite-size effects of hadron masses for both quenched and full QCD calculations. We show that they are much larger for full QCD…
A new signal for scalar top bound state production
M. Drees, M. M. Nojiri
We study the production and decay of a scalar \stst\ bound state \sigst\ at hadron supercolliders, where \st\ is the lighter stop eigenstate. If \st\ has no tree--level 2--body dec…

K. Hagiawara, M. L. Stong
We study possible deviations from the Standard Model in the reaction , where denotes a spinless neutral boson. We show how the decay angular correlation can…
Anomalous Higgs Boson Production and Decay
K. Hagiwara, R. Szalapski, D. Zeppenfeld
A non-standard symmetry breaking sector may lead to derivative couplings of the Higgs boson and thereby to anomalous interactions with the electroweak gauge bosons. In the framewor…

Youichi Yamada
We calculate the two-loop renormalization group equations for the running gaugino masses in general SUSY gauge models, improving our previous result. We also study its consequence…

We study the decays of a scalar \stst\ bound state \sigst, where \st\ is the lighter stop eigenstate. If \st\ has no tree--level 2--body decays, the dominant decay modes of \sigst\…

N. Ishizuka, Y. Shizawa
Renormalization factors for bilinear and four-quark operators with the Kogut-Susskind fermion action are perturbatively calculated to one-loop order in the general covariant gauge.…

A constraint from process to the minimal supersymmetric standard model is derived in the light stop region where the coupling between the lighter stop and the $Z^…

Nobuyuki Ishibashi, Hikaru Kawai
We construct the Hamiltonian operator of the string field theory for string theory. It describes how strings evolve in the coordinate frame, which is defined by using the geo…
Two-loop renormalization of gaugino mass in supersymmetric gauge model
Youichi Yamada
We study the two-loop renormalization group equation for the running gaugino mass in the supersymmetric gauge theory. We find that both in the \msbar and \drbar renormalization sch…

Toshiya Kawai, Yasuhiko Yamada, Sung-Kil Yang
Recently Witten proposed to consider elliptic genus in superconformal field theory to understand the relation between minimal models and Landau-Ginzburg theories. In th…

Masaharu Tanabashi
We formulate the chiral perturbation theory at the one loop level in the effective lagrangian including the meson as a dynamical gauge boson of a hidden local symmetry(HLS). Th…

We consider self-avoiding Nambu-Goto open strings on a random surface. We have shown that the partition function of such a string theory can be calculated exactly. The string susce…
