Pseudoscalar transition form factors: of the muon, pseudoscalar decays into lepton pairs, and the mixing
Pere Masjuan, Pablo Sanchez-Puertas
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. The method is gener…
and decays into lepton pairs
Pere Masjuan, Pablo Sanchez-Puertas
In this work, we calculate the branching ratios for the decays, where . These processes have tiny rates in the standard model due to sp…
- mixing in large- chiral perturbation theory: discussion, phenomenology, and prospects
Patricia Bickert, Pere Masjuan, Stefan Scherer
A systematic study of the - mixing in Large- chiral perturbation theory is presented with special emphasis on the role of the next-to-next-to-leading-order contribution…
Pseudoscalar decays into lepton pairs from rational approximants
Pablo Sanchez-Puertas, Pere Masjuan
The pseudoscalar decays into lepton pairs are analyzed with the machinery of Canterbury approximants, an extension of Padé approximants to bivaria…
Pseudoscalar-exchange contribution to from rational approximants
Pablo Sanchez-Puertas, Pere Masjuan
We present our recent results on the hadronic light-by-light pseudoscalar-exchange contribution to the anomalous magnetic moment of the muon using rational approximants. Our work p…
