$A$ dependence of the $\gamma$- and $p$-induced production of the $\Lambda (1520)$ from nuclei

Abstract

Using results of a recent calculation of the $\Lambda (1520)$ in the nuclear medium, which show that the medium width is about five times the free width, we study the A dependence of the $\Lambda (1520)$ production cross section in the reactions $\gamma A\to K^{+}\Lambda (1520)A^{\prime }$ and $pA\to p{K}^{+}\Lambda (1520)A^{\prime }$. We find a sizable A dependence in the ratio of the nuclear cross sections for heavy nuclei with respect to a light one due to the large value of the $\Lambda (1520)$ width in the medium, showing that devoted experiments, easily within reach in present facilities, can provide good information on that magnitude by measuring the cross sections studied here.
