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.

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 ...

Excited scalar and pseudoscalar mesons in the extended linear sigma model. [PDF]

Eur Phys J C Part 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.

Spectrum of scalar and pseudoscalar glueballs from functional methods. [PDF]

Eur Phys J C Part Fields, 2020
We provide results for the spectrum of scalar and pseudoscalar glueballs in pure Yang–Mills theory using a parameter-free fully self-contained truncation of Dyson–Schwinger and Bethe–Salpeter equations.

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 Mass Effects in Decays of Taus with Three Pseudoscalar Mesons [PDF]

Phys.Rev. D50 (1994) 6863-6871, 1993
We study the effects of non-vanishing pseudoscalar masses in $\tau$ decays into three mesons. The hadronic matrix elements are obtained by using the generalized structure of the chiral currents with nonvanishing pseudoscalar masses and implementing the low-lying resonances in the different channels.

Pseudoscalar Mesons and Emergent Mass [PDF]

Few-Body Systems
Despite its role in the continuing evolution of the Universe, only a small fraction of the mass of visible material can be attributed to the Higgs boson alone.

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
