Properties of the $π^{0}$ , $η$ , $η^{'}$ , $σ$ , $f_{0} (980)$ and $a_{0} (980)$ mesons and their relevance for the polarizabilities of the nucleon

Martin Schumacher

The signs and values of the two-photon couplings $F_{M γ γ}$ of mesons $(M)$ and their couplings $g_{M N N}$ to the nucleon as entering into the $t$ -channel parts of the difference of…

Electromagnetic polarizabilities and the excited states of the nucleon

Martin Schumacher

The electromagnetic polarizabilities of the nucleon are shown to be essentially composed of the nonresonant $α_{p} (E_{0 +}) = + 3.2$ , $α_{n} (E_{0 +}) = + 4.1$ ,the $t$ -channel $α^t_{p,n}=-β^t_{…
