Scalar-Pseudoscalar scattering and pseudoscalar resonances [PDF]
AIP Conference Proceedings, 2010 The interactions between the f_0(980) and a_0(980) scalar resonances and the lightest pseudoscalar mesons are studied. We first obtain the interacting kernels, without including any ad hoc free parameter, because the lightest scalar resonances are ...

Decay of the pseudoscalar glueball into scalar and pseudoscalar mesons [PDF]
Physical Review D, 2013 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.

Decay of the pseudoscalar glueball into vector, axial-vector, scalar and pseudoscalar mesons
European Physical Journal C: Particles and Fields, 2023 We resume the investigation of the ground-state pseudoscalar glueball, $$J^{PC}=0^{-+}$$ J PC = 0 - + , by computing its two- and three-body decays into vector and axial-vector quark-antiquark meson fields additional to scalar and pseudoscalar mesons ...

Reconstructing a light pseudoscalar in the Type-X two Higgs doublet model
Physics Letters B, 2017 We investigate the detectability as well as reconstructibility of a light pseudoscalar particle A, of mass in the 50–60 GeV range, which is still allowed in a Type-X (lepton-specific) two-Higgs doublet scenario.

On the constitutive pseudoscalars of hemitropic micropolar media in inverse coordinate frames [PDF]
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021 The paper is devoted to the constitutive pseudoscalars associated with the theory of hemitropic micropolar continuum. The basic concepts of pseudotensor algebra are presented. The pseudotensor form of the hemitropic micropolar elastic potential is given,

Pseudoscalars and the η′ in the holographic soft-wall model [PDF]
EPJ Web of Conferences, 2022 Pseudoscalar mesons and glueballs are studied in a model based on the AdS/QCD correspondence. Glueball masses are obtained in the pure-gauge case, while the mixing between pseudoscalar glueballs and singlet pseudoscalar mesons produces the expected mass ...

The a0(980) and f0(980) in the process Ds+→K+K−π+
Physics Letters B, 2021 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
Nuclear Physics B, 2022 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 ...

The pseudoscalar decay constant [PDF]
Nuclear Physics B - Proceedings Supplements, 2005 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 ...
