$\Lambda$-hypernuclear production in ($K^-_{\rm stop}, \pi$) reactions

Abstract

We report on calculation of the $\Lambda$ - hypernuclear production induced by the stopped $K^-$. The calculation was performed within the framework of the distorted wave impulse approximation and employed chirally motivated model for the microscopic description of the elementary $K^-$-nucleon process. The sensitivity of the calculation was tested with various wave functions of both the kaon in the initial state and the pion in the final state. Our results are closer to the experimental values then the results of previous calculations.
