B Physics and Hadronic Matrix Elements
C-H Chang, K-T Chao, X-G He +10
In a mini workshop on B Physics which were held at Dalian, China, a number of lectures was given. Around 40 participants joined the workshop. In this workshop, people discussed the…
$\etap K$ puzzle of B meson decays and new physics effects in the general two-Higgs-doublet model
Zhenjun Xiao, Chong Sheng Li, Kuang-Ta Chao
we calculate the new physics contributions to seven measured decays and $ K \etap$ in the general two-Higgs-doublet model (Model III). Within the considered pa…
Diffractive light quark jet production at hadron colliders in the two-gluon exchange model
Feng Yuan, Kuang-Ta Chao
Massless quark and antiquark jet production at large transverse momentum in the coherent diffractive processes at hadron colliders is calculated in the two-gluon exchange parametri…
Gluon fragmentation to quarkonium and test of color-octet production mechanism
Kuang-Ta Chao, Cong-Feng Qiao, Feng Yuan
We report the recent progress in the studies of D-wave heavy quarkonia production from gluon fragmentation at the Tevatron and in Z^0 decays, and the D-wave charmonia production in…
Physics in Charm Energy Region
Kuang-Ta Chao
Recent results on physics in the charm energy region are reviewed. (1) The new data and puzzles in exclusive hadronic decays of and give new challenges to the theory of…
