A factorization theorem connecting the light-cone distribution amplitudes of heavy-flavor mesons in QCD and HQET
Saadi Ishaq, Yu Jia, Xiaonu Xiong +1
The light-cone distribution amplitude (LCDA) of a heavy-light meson defined in heavy quark effective theory (HQET), is a fundamental nonperturbative input to account for innumerabl…
Exclusive decay to double at next-to-leading order in
Bin Gong, Yu Jia, Jian-Xiong Wang
Within the nonrelativistic QCD (NRQCD) factorization framework, we calculate the exclusive decay process η_b \to J/ψJ/ψto next-to-leading order in the strong coupling constant, whi…
The Outer Tracker Detector of the HERA-B Experiment. Part III: Operation and Performance
H. Albrecht
In this paper we describe the operation and performance of the HERA-B Outer Tracker, a 112674 channel system of planar drift tube layers. The performance of the HERA-B Outer Tracke…
The Outer Tracker Detector of the HERA-B Experiment Part I: Detector
H. Albrecht
The HERA-B Outer Tracker is a large system of planar drift chambers with about 113000 read-out channels. Its inner part has been designed to be exposed to a particle flux of up to…
J-ψProduction via χ_c Decays in 920 GeV pA Interactions
B Collaboration
Using data collected by the HERA-B experiment, we have measured the fraction of Jψ's produced via radiative chi_c decays in interactions of 920 GeV protons with carbon and titanium…
