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 ...

On the Neuber theory of micropolar elasticity. A pseudotensor formulation
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020 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.

On a micropolar theory of growing solids
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020 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 ...

MSSM scenarios with a light CP-odd Higgs boson [PDF]
EPJ Web of Conferences, 2019 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.

On the photon-pseudoscalar particle mixing in media and external fields
European Physical Journal C: Particles and Fields, 2021 In this work, I study the mixing of photons with pseudoscalar particles and vice-versa in the presence of an external magnetic field and a pseudoscalar field.
