Transverse Quark Distribution in Mesons - QCD Sum Rule Approach -

Su H. Lee, T. Hatsuda, G. A. Miller

QCD sum rules are used to compute the first few moments of the mesonic quark momentum. Transverse, longitudinal and mixed transverse-longitudinal components are examined. The trans…

Electroweak Discussion Section Summary

C. S. Kim

I summarize our work of electroweak discussion section held at the 14th International Workshop on Weak Interactions and Neutrinos. We discussed about a few physics topics related t…

Anomalous Gauge-Boson Couplings in High Energy ep Collisions

C. S. Kim, Jungil Lee, H. S. Song

We investigate the sensitivity of total cross sections of to CP-conserving non-standard couplings. We include all the important production mechanisms an…

Topological Field Theory of Vortices over Closed Kahler Manifolds

Hyuk-jae Lee

By dimensional reduction, Einstein-Hermitian equations of n + 1 dimensional closed Kahler manifolds lead to vortex equations of n dimensional closed Kahler manifolds. A Yang-Mills-…

Topological Field Threories on The Compact Kahler Complex Surfaces

Hyuk-jae Lee

The structure of topological quantum field theories on the compact Kahler manifold is interpreted. The BRST transformations of fields are derived from universal bundle and the obse…

Hadronic production and the Gottfried Sum Rule

M. A. Doncheski, F. Halzen, C. S. Kim +1

The difference in production rate between and at hadron colliders is very sensitive to the the difference between up- and down-quark distributions in the proton. This s…

Holomorphic Yang-Mills Theory on Compact Kähler Manifolds

Jae-Suk Park

We propose holomorphic Yang-Mills theory on compact Kähler manifolds and show that there exists a simple mapping from the topological Yang-Mills theory. It follows that…

N=2 Topological Yang-Mills Theory on Compact Kähler Surfaces

Jae-Suk Park

We study a topological Yang-Mills theory with fermionic symmetry. Our formalism is a field theoretical interpretation of the Donaldson polynomial invariants on compact Kähler…

Flavor Democracy in Standard Models at High Energies

G. Cvetic, C. S. Kim

It is possible that the standard model (SM) is replaced around some transition energy $\E_{tr}$ by a new, possibly Higgsless, ``flavor gauge theory'' such that the Yukawa (running)…

Twist-4 Matrix Elements of the Nucleon from Recent DIS Data at CERN and SLAC

S. Choi, T. Hatsuda, Y. Koike +1

We analyse the recent precision measurements of the lepton-hadron deep inelastic scattering at CERN and SLAC to extract model independent constraints among the nucleon matrix eleme…

Associated production as a probe of the polarized gluon distribution

M. A. Doncheski, C. S. Kim

Associated production of and a has recently been proposed as clean probe of the gluon distribution. The same mechanism can be used to probe the polarized gluon content of…
