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 in Nuclear Medium [PDF]
Nuclear Many-Body and Medium Effects in Nuclear Interactions and Reactions, 2003 The behavior of pseudoscalar mesons in nuclear medium is reviewed with an emphasis on the possibility of their Bose-Einstein condensation in dense matter.

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.

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 ...

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 ...

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.

Quantum Geometric Engineering of Dual Hall Effects in 2D Antiferromagnetic Bilayers via Interlayer Magnetic Coupling. [PDF]
Adv Sci (Weinh)Precise tuning of interlayer magnetic coupling in two‐dimensional bilayers enables control over altermagnetic and PT‐symmetric antiferromagnetic phases. This dual‐phase platform yields two intrinsic Hall responses: a Berry curvature–driven linear anomalous Hall effect and a quantum metric–induced second‐order nonlinear anomalous Hall effect ...

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