Differential cross sections for Lambda(1520) using photoproduction at CLAS
Abstract
The reaction gamma p -> K+Lambda(1520) using photoproduction data from the CLAS g12 experiment at Jefferson Lab is studied. The decay of Lambda(1520) into two exclusive channels, Sigma(+)pi(-) and Sigma(-)pi(+), is studied from the detected K+, pi(+), and pi(-) particles. A good agreement is established for the Lambda(1520) differential cross sections with the previous CLAS measurements. The differential cross sections as a function of center-of-mass angle are extended to higher photon energies. Newly added are the differential cross sections as a function of invariant four-momentum transfer t, which is the natural variable to use for a theoretical model based on a Regge-exchange reaction mechanism. No new N* resonances decaying into the K+Lambda (1520) final state are found.
