QCD sum rules and chiral logarithms

Su Houng Lee, Seungho Choe, Thomas D. Cohen +1

Standard QCD sum-rule analyses of the nucleon mass give results that are inconsistent with chiral perturbation theory due to an overly simple continuum ansatz on the phenomenologic…

Novel Approach to Confront Electroweak Data and Theory

K. Hagiwara, D. Haidt, C. S. Kim +1

A novel approach to study electroweak physics at one-loop level in generic theories is introduced. It separates the 1-loop corrections into two pieces…

Determination of V_ub at the Z-boson resonance

C. S. Kim, A. D. Martin

We show that the observation of energetic charged leptons from semileptonic becays at the LEP and SLC --boson factories offers a unique opportunity to measure the quark mixi…

Hawking Radiation of Dirac Fields in the (2+1)-Dimensional Black Hole space-time

S. Hyun, Y. -S. Song, J. H. Yee

By calculating the response function, we study the Hawking radiation of massless Dirac fields in the (2+1)-dimensional black hole geometry. We find that the response function has P…

Photon Vector Meson Coupling and Vector Meson Properties at Low Temperature Pion Gas

Su Houng Lee, Chungsik Song, Hiroyuki Yabu

The vector and axial vector current mixing phenomena at low temperature pion gas by Dey, Eletsky and Ioffe, leads to the low temperature correction of the photon-vector meson coupl…

Testing J/psi Production and Decay Properties in Hadronic Collisions

C. S. Kim, E. Mirkes

The polar and azimuthal angular distributions for the lepton pair arising from the decay of a J/psi meson produced at transverse momentum p_T balanced by a photon [or gluon] in had…

Gaussian approximation of the (2+1) dimensional Thirring model in the functional Schrödinger picture

S. J. Hyun, G. H. Lee, J. H. Yee

The (2+1)-dimensional Thirring model is studied by using the Gaussian approximation method in the functional Schrödinger picture. Although the dynamical symmetry breaking does not…

New Approach for Measuring at Future -Factories

C. S. Kim, Pyungwon Ko, Daesung Hwang +1

It is suggested that the measurements of hadronic invariant mass () distributons in the inclusive decays can be useful in extracting the CKM matri…

Magetic softening of Young's modulus of amorphous Fe90Zr10

S. H. Park, Y. H. Jeong

The Young's modulus and the internal friction of amorphous FeZr alloy were measured near the Curie temperature using the vibrating reed technique. The modulus shows s…

Quark-Lepton Flavor Democracy and the Non-Existence of the Fourth Generation

G. Cvetic, C. S. Kim

In the Standard Model with two Higgs doublets (type II), which has a consistent trend to a flavor gauge theory and its related flavor democracy in the quark and the leptonic sector…

Inclusion of Z->b b-bar vertex corrections in Precision Electroweak Tests on the Sp(6)_L X U(1)_Y Model

Gye T. Park, T. K. Kuo

We extend our previous work on the precision electroweak tests in the Sp(6)_L X U(1)_Y family model to include for the first time the important Z->b b-bar vertex corrections encode…

Polyakov's Spin Factor for a Classical Spinning Particle via BRST Invariant Path Integral

Jin-Ho Cho, Seungjoon Hyun, Hyuk-Jae Lee

For the `classical' formulation of a massive spinning particle, the propagator is obtained along with the spin factor. We treat the system with two kinds of constraints that were r…

Measuring at future B-Factories

C. S. Kim, Daesung Hwang, Pyungwon Ko +1

We calculate the so--called Fermi motion parameter of ACCMM model using the variational method in a potential model approach. We also propose hadronic invariant mass distr…

A Covariant Formulation of Classical Spinning Particle

Jin-Ho Cho, Seungjoon Hyun, Jae-Kwan Kim

Covariantly we reformulate the description of a spinning particle in terms of the Poincaré group. We also construct a Lagrangian which entails all possible constraints explicitly;…
