Polarized J/psi production at CLEO
Seungwon Baek, P. Ko, Jungil Lee +1
Polarizations of the prompt 's produced in the annihilation at CLEO energy ( GeV) are considered in the framework of NRQCD factorization formalism.…
Color-octet mechanism and J/psi polarization at LEP
Seungwon Baek, P. Ko, Jungil Lee +1
Polarized heavy quarkonium productions in decays are considered. We find that polarizations of the produced quarkonia are independent of that of the parent Z^0 provided that…
Color-octet mechanism in J/psi productions
P. Ko
I review recent developments in theoretical understandings of J/psi productions in various processes at Tevatron, B decay and J/psi photoproduction including the color-octet mechan…
Color-octet mechanism in
Pyungwon Ko, Jungil Lee, H. S. Song
Photoproduction of is considered including the color-octet contributions from the various partial wave states, = , and . The production cro…
Inclusive wave charmonium productions in decays
Pyungwon Ko, Jungil Lee, H. S. Song
The inclusive wave charmonium production rates in decays are considered using the Bodwin-Braaten-Lepage (BBL) approach, including the relativistic corrections and the color…
Search for and states in the annihilations
P. Ko
Productions and decays of spin-singlet wave charmonium states, and , in the annihilations are considered in the QCD multipole expansi…
