Glueball-Induced Partonic Energy Loss in Quark-Gluon Plasma
Dong-Pil Min, Nikolai Kochelev
We discuss the energy loss of energetic parton jets in quark-gluon plasma above the deconfinement temperature by the interaction with scalar and pseudoscalar glueballs. It is…
On the contribution to the QCD sum rules for the light tetraquark
Hee-Jung Lee, N. I. Kochelev
We perform a QCD sum rule analysis for the light tetraquark taking into account the contribution arising from the two pion intermediate state. With the interpolating currents…
Instanton-Induced Polarization in Exclusive Hyperon Photoproduction
Nikolai Kochelev
It is shown that instantons can provide an explanation of the strong polarization transfer observed in exclusive hyperon photoproduction at JLab.
Effects of QCD Vacuum and Stability of H Dihyperon
A. E. Dorokhov, N. I. Kochelev
Within the composite quark model taking into account the interaction of quarks in the bag with vacuum fields of QCD the masses of H (I=0,S=-2,J=0,1^C) and H* (I=0,S=-2,J=1,1^C) dih…
Diffractive Lambda_c^+ Productions in Polarized pp Reactions and Polarized Gluon Distribution
N. I. Kochelev, T. Morii, S. Oyama
To test the model of the polarized gluon distribution in the proton, we propose a new process, diffractive productions in polarized reactions, which will…
