Hidden charm pentaquarks with color-octet substructure in QCD Sum Rules
Alexandr Pimikov, Hee-Jung Lee, Pengming Zhang
We study the hidden-charm pentaquark states with spins 1/2, 3/2, and 5/2 within the QCD sum-rule approach. First, we construct the currents for the particular configu…
Testing the tetraquark mixing framework from QCD sum rules for
Hee-Jung Lee, K. S. Kim, Hungchong Kim
According to a recent proposal of the tetraquark mixing framework, the two light-meson nonets in the channel, namely the light nonet composed of , $K_0^* (…
Gluonic Distribution in the Constituent Quark and Nucleon Induced by the Instantons
Baiyang Zhang, Nikolai Kochelev, Hee-Jung Lee +1
Instanton effects can give large contribution to strong interacting processes, especially at the energy scale where perturbative QCD is no longer valid. However instanton contribut…
Exotic glueball states in QCD Sum Rules
Alexandr Pimikov, Hee-Jung Lee, Nikolai Kochelev +2
The lowest dimension three-gluon currents that couple to the exotic glueballs have been constructed using the helicity formalism. Based on the constructed currents, we o…
Comment on "Finding the Glueball" [arXiv:1408.3995]
Alexandr Pimikov, Hee-Jung Lee, Nikolai Kochelev
A Comment on the Letter by C. F. Qiao and L. Tang, Phys. Rev. Lett. 113, 221601 (2014) [arXiv:1408.3995]
Is the exotic glueball a pure gluon state ?
Alexandr Pimikov, Hee-Jung Lee, Nikolai Kochelev +1
We present a new calculation of the mass and width of the exotic glueball in the framework of the QCD sum rules. We next construct a new current which couples to a pure $0…
