Cross Section Analysis of ep → K<sup>+</sup>Λ<sup>*</sup>
POSTER
Abstract
In nuclear particle physics, there is a discrepancy between theory and experiment concerning the numbers of existing nucleon resonances. Current models of nucleon resonances predict far more states than have been observed. To investigate this problem, Λ(1520) baryons are reconstructed from a K- and a proton from the CLAS12 detector. Using the reaction ep → K+K- p with electrons of energy 10 GeV, the invariant mass of the K+Λ(1520) system is used to determine yields, which are efficiency corrected and normalized to produce cross sections. The cross sections of the K+Λ(1520) system assist in uncovering the resonance spectrum. In this presentation, the cross section for the reaction ep → K+Λ(1520) in the range W = 2 to 5 GeV will be presented.
