abstract
We reinvestigate $K^*\Lambda(1116)$ photoproduction off the nucleon target, based on an effective Lagrangian approach. We include higher nucleon resonances such as $N(2000)\, 5/2^+$, $N(2060)\,5/2^-$, $N(2120)\,3/2^-$, and $N(2190)\,7/2^-$, of which the data are taken from the 2012 edition of Review of Paritcle Physics, in addition to the $t$-channel diagrams ($K$, $K^*$, and $\kappa$), the $s$-channel nucleon, and $u$-channel hyperon($\Lambda$, $\Sigma$, and $\Sigma^*$) contributions. We find that the $N(2120)\,3/2^-$ and $N(2190)\,7/2^-$ resonances are essential in describing the new CLAS data for charged $K^*$ photoproduction. On the other hand, they rarely affect for neutral $K^*$ photoproduction.

Roles of $\Delta(1232)$, $N^*(1520)$, and $N^*(1650)$ resonances in $\gamma p\to \pi^0 \pi^0 p$ reaction within an effective Lagrangian approach
A tree-level effective Lagrangian model with Delta(1232), N*(1520), and N*(1650) reproduces the LEPS2/BGOegg gamma p to pi0 pi0 p data, assigning Delta(1232) to s-channel nucleon-pole production and the two N* resonan...
