Description:
We study a scenario allowing a solution of the strong charge parity problem via the Peccei-Quinn mechanism, implemented in gravity with torsion. In this framework there appears a torsion-related pseud

Description:
We present the calculation of the hyperon forward spin polarizability γ0 using manifestly Lorentz-covariant baryon chiral perturbation theory including the intermediate contribution of the spin-3/2 st

Description:
We present a high-quality description of the deuteron electromagnetic form factors in a soft-wall anti-de Sitter/quantum chromodynamics approach. We first propose an effective action describing the dy

Description:
Using global fits of valence u and d quark parton distributions and data on quark and nucleon form factors in the Euclidean region, we derive a light-front quark model for the nucleon structure consis

Description:
We discuss a holographic soft-wall model that consider several Fock states in nucleon description. In our approach nucleon structure is a superposition of a three-valence quark state with high Fock st

Description:
We provide a new insight into the problem of generating the hadron mass spectrum in the framework of the covariant confined quark model. One of the underlying principles of this model is the composite

Description:
We analyze the tauonic semileptonic baryon decays Λ0b→Λ+c+τ−+ν̄ τ with particular emphasis on the lepton helicity flip contributions which vanish for zero lepton masses. We calculate the total rate, d

Description:
We derive the lowest-order qq valence light-front wave function for the pion with Lz = 0 and |Lz| = 1, which reproduces its valence parton distribution and the electromagnetic form factor consistent w

Description:
The effect of isoscalar S-wave multichannel ππ→ππ, KK¯¯,ηη scattering is considered in the analysis of decay data of the Υ-mesons. We show that when allowing for the final state interaction contributi

Description:
Recently there has been much interest in the tauonic semileptonic meson decays B→D+τ+ντ and B→D∗+τ+ντ, where one has found larger rates than what is predicted by the Standard Model. We analyze the cor

Description:
We present a unified analysis of the decays of bottomonia Υ(mS)→Υ(nS)ππ (m>n, m=2,3,4,5, n=1,2,3), charmonia J/ψ→ϕ(ππ,KK¯), ψ(2S)→J/ψππ, and the isoscalar S-wave processes ππ→ππ,KK¯,ηη. In this analys
