Radiative decays of vector and pseudoscalar nonets
EPJ Web of Conferences, 2012 Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Pseudoscalar Portal Dark Matter and New Signatures of Vector-like Fermions
, 2016 Fermionic dark matter interacting with the Standard Model sector through a pseudoscalar portal could evade the direct detection constraints while preserving a WIMP miracle.

Magneto-optic effects of the cosmic microwave background
Nuclear Physics B, 2018 Generation of magneto-optic effects by the interaction of the CMB with cosmic magnetic fields is studied. Effects which generate polarization such as the Cotton–Mouton effect, vacuum polarization and photon–pseudoscalar mixing in external magnetic field ...

Renormalization of the pseudoscalar operator at four loops in QCD
Journal of High Energy PhysicsWe present the renormalization constant of the pseudoscalar operator defined with a non-anticommuting γ 5 in dimensional regularization up to four-loop order in perturbative Quantum Chromodynamics (QCD).

QUARK STRUCTURE OF PSEUDOSCALAR MESONS [PDF]
International Journal of Modern Physics A, 2000 I review to which extent the properties of pseudoscalar mesons can be understood in terms of the underlying quark (and eventually gluon) structure. Special emphasis is put on the progress in our understanding of η–η′ mixing. Process-independent mixing parameters are defined, and relations between different bases and conventions are studied.

Dalitz Analysis of B->K+pi+pi- and B->K+K+pi-
, 2004 We report results of the Dalitz analysis of the three-body charmless B->K+pi+pi- and B->K+K+K- decays based on a 140fb^{-1} data sample collected with the Belle detector.

Exact formula of the spectrum of the pseudoscalar octet
Physics Letters B, 2015 Non-perturbative proof is presented of a generalized version of Goldstone theorem, where the Lagrangian conserves an approximate SU(3) chiral symmetry, that both quark masses and electromagnetism make contributions to the masses of spinless particles of ...

Internal symmetry implications of the Veneziano model in pseudoscalar-pseudoscalar scattering
Nuclear Physics B, 1969 Abstract The leading order Veneziano model amplitudes for ( J P ) 0 − × 0 − → 0 − × 0 − scattering ∗∗ constrained by the absence of “exotic” resonances, is shown to predict the coupling constant relation of SU(3) coupled with the quark-model/SU(6) ideal singlet-octet mixing in the 1 − , 2 + , nonets.
