Strong force fields and stabilities of the nucleon and singly heavy baryon
June-Young Kim, Hyun-Chul Kim, Maxim V. Polyakov +1
We investigate the strong force fields and stabilities of the nucleon and the singly heavy baryon within the framework of the chiral quark-soliton model. Having constructed t…
On the second Gegenbauer moment of -meson distribution amplitude
Maxim V. Polyakov, Hyeon-Dong Son
Using the soft pion theorem, crossing, and the dispersion relations for the two pion distribution amplitude (DA) we argue that the second Gegenbauer moment the -meson DA ($a…
Nucleon quasi-Parton Distributions in the large N limit
Hyeon-Dong Son, Asli Tandogan, Maxim V. Polyakov
In this letter, we investigate the nucleon quasi-parton distribution functions in the chiral quark soliton model. We derive a set of sum-rules depending on the velocity of the nucl…
Nucleon gravitational form factors from instantons: forces between quark and gluon subsystems
Maxim V. Polyakov, Hyeon-Dong Son
Using the instanton picture of the QCD vacuum we compute the nucleon form factor of the quark part of the energy momentum tensor (EMT). This form factor describes the…
through the looking glass of flavour SU(3)
Maxim V. Polyakov, Hyeon-Dong Son, Bao-Dong Sun +1
We perform the flavour analysis of the recently discovered hyperon. We find that well known (four star) resonance with quantum numbers of is…
Weak generalized form factors and transverse transition quark-spin density from the instanton vacuum
Hyeon-Dong Son, Seung-il Nam, Hyun-Chul Kim
We investigate the generalized transition vector and tensor form factors, from which we derive the transverse quark spin density in the course of the transition, b…
