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 ...

Photoproduction of Pseudoscalar Mesons [PDF]
Nuclear Physics A, 2002 Experiments that study the photoproduction of pseudoscalar mesons; pions, etas and kaons, have the potential to increase our knowledge of baryon and hyperon resonance properties. Recent experiments at JLab, Mainz, GRAAL, and Bonn are beginning to produce

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.

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 ...

A case for resonant X-ray Bragg diffraction by a collinear antiferromagnet Li<sub>2</sub>Ni<sub>3</sub>P<sub>4</sub>O<sub>14</sub>. [PDF]
Acta Crystallogr B Struct Sci Cryst Eng MaterAmplitudes for resonant X‐ray diffraction by collinear antiferromagnet Li2Ni3P4O14 that include permitted Dirac multipoles, e.g. anapoles, are investigated. Chiral signatures for the rotation of X‐ray helicity are described.Magnetic axial and polar (Dirac) nickel multipoles contribute to resonant X‐ray Bragg amplitudes in a symmetry‐informed analysis ...

Nonminimally coupled pseudoscalar inflaton [PDF]
Physical Review D, 2018 We consider a scenario in which the inflaton $ $ is a pseudoscalar field non-minimally coupled to gravity through a term of the form ${\cal X} R ^2$. The pseudoscalar is also coupled to a $U(1)$ gauge field (or an ensemble of ${\cal N}$ gauge fields) through an axial coupling of the form $ F \tilde{F}$. After M. M. Anber and L. Sorbo, Phys. Rev.

Pseudoscalar mass effects in the decays of τ with three pseudoscalar mesons [PDF]
Physical Review D, 1994 We study the effects of non-vanishing pseudoscalar masses in $ $ 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.

Production of a Higgs pseudoscalar plus two jets in hadronic collisions [PDF]
, 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
