The a0(980) and f0(980) in the process Ds+→K+K−π+
In this work, we have investigated the process Ds+→K+K−π+, taking into account the contributions from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary approach, and also the intermediate ϕ resonance.

Analysis of the pseudoscalar hidden-charm tetraquark states with the QCD sum rules
In this work, we take all the color-antitriplet diquarks, such as the scalar, pseudoscalar, vector, axialvector and tensor diquarks, as the basic constituents to construct the local pseudoscalar four-quark currents without importing the explicit P-waves ...

Decay of the pseudoscalar glueball into scalar and pseudoscalar mesons [PDF]
We study a chiral Lagrangian which describes the two- and three-body decays of a pseudoscalar glueball into scalar and pseudoscalar mesons. The various branching ratios are a parameter-free prediction of our approach. We compute the decay channels for a pseudoscalar glueball with a mass of 2.6 GeV, as predicted by Lattice QCD in the quenched ...

On a micropolar theory of growing solids
The present paper is devoted to the problem of boundary conditions formulation in the growing micropolar solid mechanics. The static equations of the micropolar continuum in terms of relative tensors (pseudotensors) are derived due to virtual work ...

On the Neuber theory of micropolar elasticity. A pseudotensor formulation
The present paper deals with a pseudotensor formulation of the Neuber theory of micropolar elasticity. The dynamic equations of the micropolar continuum in terms of relative tensors (pseudotensors) are presented and discussed.

The pseudoscalar decay constant [PDF]
We discuss insights that may be drawn from our recent 2 flavour O(a)--improved Wilson quark simulations. We discuss the evidence of the onset of chiral logarithms in the pion decay constant. An overview is given of current extrapolation methods and a modification of chiral perturbation theory is presented as an approach for sensibly extrapolating to ...

Pseudoscalar-Meson Contributions to g−2 via Schwinger’s Sum Rule [PDF]
The Schwinger sum rule is presented as a new promising tool to study the hadronic contributions to the muon anomalous magnetic moment. In particular, we show preliminary results for the light-by-light scattering contribution of pseudoscalar ...

Where is the pseudoscalar glueball? [PDF]
The pseudoscalar mesons with the masses higher than 1 GeV are assumed to belong to the meson decuplet including the glueball as the basis state supplementing the standard $SU(3)_F$ nonet of light $q\bar{q}$ states $(u,d,s)$. The decuplet is investigated by means of an algebraic approach based on hypothesis of vanishing the exotic $SU(3)_F$ commutators ...

MSSM scenarios with a light CP-odd Higgs boson [PDF]
The possibility of the presence of a light pseudoscalar with the mass of 28 GeV in the MSSM Higgs sector extended by dimension-six operators is analyzed. The perturbative unitarity and vacuum stability constraints are discussed.
