Influence of the axial anomaly on the decay
Lisa Olbrich, Miklós Zétényi, Francesco Giacosa +1
The decay width of is as large as that of . This is in evident conflict with simple expectations based on flavor symmetry and phase s…
Three-flavor chiral effective model with four baryonic multiplets within the mirror assignment
L. Olbrich, M. Zétényi, F. Giacosa
We study three-flavor octet baryons by using the so-called extended Linear Sigma Model (eLSM). Within a quark-diquark picture, the requirement of a mirror assignment naturally lead…
A Three-Flavor Chiral Effective Model with Four Baryonic Multiplets within the Mirror Assignment
Lisa Olbrich, Miklós Zétényi, Francesco Giacosa +1
In the case of three quark flavors, (pseudo)scalar diquarks transform as antiquarks under chiral transformations. We construct four spin-1/2 baryonic multiplets from left- and righ…
Phenomenology of axial-vector and pseudovector mesons: decays and mixing in the kaonic sector
Florian Divotgey, Lisa Olbrich, Francesco Giacosa
We study the decays of the lightest axial-vector and pseudovector mesons, interpreted as quark-antiquark states, into a vector and a pseudoscalar meson. We show that the quarkonium…
