Pion-induced production of $\Lambda(1520)$ hyperons on nuclei near threshold
Abstract
We study the pion-induced inclusive hyperon production from nuclei near threshold within a nuclear spectral function approach accounting for incoherent primary meson--proton production processes. We calculate the absolute differential and total cross sections for the production of hyperons off carbon and tungsten nuclei at laboratory angles of 0--10, 10--45 and 45--85 by mesons with momentum of 1.7 GeV/c as well as their relative (transparency ratio) differential and integral yields from these nuclei within four scenarios for their total in-medium width. We demonstrate that these absolute observables, contrary to the relative ones, reveal some sensitivity to the in-medium width. Therefore, their measurement in a dedicated experiment at the GSI pion beam facility will allow to shed light on this width.
