Gluonic components of the pion and the transition form factor
N. I. Kochelev, V. Vento
We propose an effective lagrangian for the coupling of the neutral pion with gluons whose strength is determined by a low energy theorem. We calculate the contribution of the gluon…
Triquark correlations and pentaquarks in a QCD sum rule approach
Hee-Jung Lee, N. I. Kochelev, V. Vento
The role of quark correlations in the description of hadron dynamics in many domains of physics, from low energy dynamics to very hot(dense) systems, is being appreciated. Strong c…
Atiyah-Manton Approach to Skyrmion Matter
B. -Y. Park, D. -P. Min, M. Rho +1
We propose how to approach, and report on the first results in our effort for, describing nuclear matter starting from the solitonic picture of baryons which is supposed to represe…
A mechanism for the Double-Spin Asymmetry in Electromagnetic Production at HERMES
N. I. Kochelev, D. -P. Min, V. Vento +1
We calculate the contribution of meson and pomeron exchanges to the double-spin asymmetry in -meson electromagnetic production at HERMES energies. We show that the observed doub…
Evidence for the flavor singlet axial anomaly related effects in meson electromagnetic production at large momentum transfers
N. I. Kochelev, V. Vento
The gluonic contributions to the conventional PCAC formulas due to flavor singlet axial anomaly have been instrumental in explaining the mass of the and providing a pl…
Instantons and the Rule
N. I. Kochelev, V. Vento
The instanton induced interaction leads to a significant enhancement of the weak amplitude determining the rule, through the contribution of operators with dimension…
Instantons and Meson Production near threshold in NN collisions
N. I. Kochelev, V. Vento, A. V. Vinnikov
An enhancement for the production in proton-neutron collisions as compared with that in proton-proton scattering has been recently observed. We present a calculation for the pr…
Further Comments on a Vanishing Singlet Axial Vector Charge
T. P. Cheng, N. I. Kochelev, V. Vento
The recent suggestion of a vanishing flavor-singlet axial charge of nucleon due to a nontrivial vacuum structure is further amplified. A perturbative QCD discussion, applicable for…
