Pseudoscalar transition form factors: (g − 2) of the muon, pseudoscalar decays into lepton pairs, and the η – η′ mixing

open access: yesEPJ Web of Conferences, 2016
We present our model-independent and data-driven method to describe pseudoscalar meson transition form factors in the space- and (low-energy) time-like regions.

Is there a scalar or pseudoscalar at 95 GeV?

open access: yesPhysical Review D
We discuss the possibility of interpreting the recent experimental hints in favor of a 95 GeV resonance with extensions of the Standard Model featuring an extra Higgs doublet and SM scalar (2HDM+s) or pseudoscalar singlet (2HDM+a). We compare the possibility of reproducing the experimental anomalies with the theoretical constraints on the extended ...

Veneziano's Model for Pseudoscalar-Pseudoscalar Scattering, Factorization and the Nonet Ansatz [PDF]

open access: yesProgress of Theoretical Physics, 1969
Crossing·symmetric, Regge behaved amplitudes of the Veneziano type are constructed for Ps-Ps scattering, where Ps denotes the pseudoscalar meson octet. Factorization of the parent and the first (odd) daughter Regge trajectories is investigated in detail.
