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 ...

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 dynamically generated.

Production of a Higgs pseudoscalar plus two jets in hadronic collisions [PDF]
Phys.Rev. D59 (1999) 057504, 1998 We consider the production of a Higgs pseudoscalar accompanied by two jets in hadronic collisions. We work in the limit that the top quark is much heavier than the Higgs pseudoscalar and use an effective Lagrangian for the interactions of gluons with the pseudoscalar.

QCD Corrections to Production of Higgs Pseudoscalars [PDF]
Phys.Rev.D49:551-554,1994, 1993 Models of electroweak symmetry breaking with more than a single doublet of Higgs scalars contain a neutral pseudoscalar boson. The production of such a pseudoscalar in hadron collisions proceeds primarily via gluon fusion through a top-quark loop (except for those models in which the pseudoscalar coupling to bottom quarks is strongly enhanced).

Pseudoscalar Form Factors in Tau-Neutrino Nucleon Scattering [PDF]
Phys.Lett. B591 (2004) 113-118, 2004 We investigate the pseudoscalar transition form factors of nucleon for quasi-elastic scattering and \Delta resonance production in tau-neutrino nucleon scattering via the charged current interactions. Although the pseudoscalar form factors play an important role for the \tau production in neutrino-nucleon scattering, these are not known well.

The light pseudoscalar Higgs boson in NMSSM [PDF]
AIPConf.Proc.903:193-196,2007, 2006 We study the associated production of a very light pseudoscalar Higgs boson with a pair of charginos. The novel signature involves a pair of charged leptons from chargino decays and a pair of photons from the pseudoscalar Higgs boson decay, plus large missing energy at the LHC and ILC. The signal may help us to distinguish the NMSSM from MSSM, provided

The Isgur-Wise Function: A Lattice Determination from Pseudoscalar --> Pseudoscalar Form Factors [PDF]
Nucl.Phys.Proc.Suppl.34:486-488,1994, 1993 Form factors for pseudoscalar --> pseudoscalar decays of heavy-light mesons are found in quenched lattice QCD with heavy-quark masses in the range of approximately 1-2 GeV. The Isgur-Wise function, $\xi(\omega)$, is extracted from these form factors. Results are in good agreement with $\xi(\omega)$ derived from CLEO measurements for B --> D*.

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.

Excited scalar and pseudoscalar mesons in the extended linear sigma model [PDF]
European Physical Journal C: Particles and Fields, 2017 We present an in-depth study of masses and decays of excited scalar and pseudoscalar $${\bar{q}}q$$ q ¯ q states in the Extended Linear Sigma Model (eLSM). The model also contains ground-state scalar, pseudoscalar, vector and axial-vector mesons.

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,
