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…

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…

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…

Average Kinetic Energy of Heavy Quark and Virial Theorem

Dae Sung Hwang, C. S. Kim, Wuk Namgung

We derive the virial theorem of the relativistic two-body system for the study of the B-meson physics. It is also shown that the solution of the variational equation always satisfi…

Form Factors for Exclusive Semileptonic --Decays

C. S. Kim, Jae Kwan Kim, Yeong Gyun Kim +1

We investigate the form factors for exclusive semileptonic decays of -meson to , based on the parton picture and helped by the results of the HQET. We obtain the numeric…

and Constraints on Supergravity Models

Gye T. Park

In the light of the top quark discovered very recently by CDF, we investigate the possibility of narrowing down the allowed top quark masses by combining for the first time only tw…

A Model-independent Way to Measure

C. S. Kim

We propose a new model-independent method, to determine the ratio , which is theoretically described by the phase space factor and the well-known perturbative QCD…

A New Model-independent Method of Determining |V_{ub}/V_{cb}|

C. S. Kim

In order to determine the ratio of CKM matrix elements |V_{ub}/V_{cb}| (and |V_{ub}|), we propose a new model-independent method based on the heavy quark effective theory, which is…

Average Kinetic Energy of Heavy Quark in Semileptonic B Decay

Dae Sung Hwang, C. S. Kim, Wuk Namgung

Within the ACCMM model the average kinetic energy of heavy quark in a heavy-light meson is calculated as , solely from the fact…

symmetry restoration in QCD with flavors

Su H. Lee, T. Hatsuda

Recently, there have been reports that the chirally restored phase of QCD is effectively symmetric under rather than . We supplement t…
