In this letter, we report the results for the isovector polarized quark quasi-distribution functions Δu(x,v)−Δd(x,v) in the large-Nc limit, calculated within the chiral quark-soliton model. It is shown that the polarized quark quasi-distributions

We perform the flavour SU(3) analysis of the recently discovered Ω(2012) hyperon. We find that well known (four star) Δ(1700) resonance with quantum numbers of JP=3/2− is a good candidate for the decuplet partner of Ω(2012) if the branching for

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 nucleon and on the Dirac matrix defining the distribution functions. We pr

Abstract Using the instanton picture of the QCD vacuum we compute the nucleon c¯Qt $$ {\overline{c}}^Q(t) $$ form factor of the quark part of the energy momentum tensor (EMT). This form factor describes the non-conservation of the quark part of EMT

We investigate the generalized K→π transition vector and tensor form factors, from which we derive the transverse quark spin density in the course of the K→π transition, based on the nonlocal chiral quark model from the instanton vacuum. The re

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 ρ-meson DA (a2(ρ)), is most probably negative. This result is at variance with the maj

We investigate the strong force fields and stabilities of the nucleon and the singly heavy baryon $\Sigma_c$ within the framework of the chiral quark-soliton model. Having constructed the pion mean fields in the presence of the $N_c-1$ level quarks s

We perform the flavour $SU(3)$ analysis of the recently discovered $\Omega(2012)$ hyperon. We find that well known (four star) $\Delta(1700)$ resonance with quantum numbers of $J^P=3/2^-$ is a good candidate for the decuplet partner of $\Omega(2012)$
