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 ...

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.

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.

Mixing of Pseudoscalar Mesons [PDF]

Physica Scripta, 2002
Eta-eta' mixing is discussed in the quark-flavor basis with the hypothesis that the decay constants follow the pattern of particle state mixing. On exploiting the divergences of the axial vector currents - which embody the axial vector anomaly - all ...

Thermal quarkonium physics in the pseudoscalar channel [PDF]

Journal of High Energy Physics, 2017
The pseudoscalar correlator is an ideal lattice probe for thermal modifications to quarkonium spectra, given that it is not compromised by a contribution from a large transport peak.

Seed-Mediated Growth and Advanced Characterization of Chiral Gold Nanorods. [PDF]

Adv Mater
Recent progress in bottom‐up wet‐chemical synthesis of gold nanoparticles has created remarkable opportunities to produce nanoparticles with well‐defined chiral shapes and strong chiroptical activities. This perspective focuses on the seed‐mediated synthesis of chiral gold nanorods as a convenient case of chiral morphogenesis.

Nucleon axial and pseudoscalar form factors from lattice QCD at the physical point [PDF]

Physical Review D, 2020
We compute the nucleon axial and induced pseudoscalar form factors using three ensembles of gauge configurations, generated with dynamical light quarks with mass tuned to approximately their physical value.

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.
