Search for High-Mass Resonances Decaying to K Lamda*

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, $\Lambda $(1520) baryons are reconstructed from a K- and a proton from the CLAS12 detector. Using the reaction ep$\to $K$+$K-p with electrons of energy 10 GeV, the invariant mass of the K$+ \quad \Lambda $(1520) system is used to determine yields, which are adjusted using efficiency corrections calculated from Monte Carlo simulation. The corrected yields of the K$+ \quad \Lambda $(1520) system assist in uncovering the resonance spectrum. In this presentation, efficiency-corrected yields in terms of the center-of-mass energy W for the K$+ \quad \Lambda $(1520) system in the range W $=$ 2 to 5 GeV will be presented.
