Differential cross sections for Λ ( 1520 ) using photoproduction at CLAS
Differential cross sections for Λ ( 1520 ) using photoproduction at CLAS
The reaction γp→K+Λ(1520) using photoproduction data from the CLAS g12 experiment at Jefferson Lab is studied. The decay of Λ(1520) into two exclusive channels, Σ+π− and Σ−π+, is studied from the detected K+, π+, and π− particles. A good agreement is established for the Λ(1520) differential cross se...

The reaction γp→K+Λ(1520) using photoproduction data from the CLAS g12 experiment at Jefferson Lab is studied. The decay of Λ(1520) into two exclusive channels, Σ+π− and Σ−π+, is studied from the detected K+, π+, and π− particles. A good agreement is established for the Λ(1520) differential cross sections with the previous CLAS measurements. The differential cross sections as a function of CM angle are extended to higher photon energies. Newly added are the differential cross sections as a function of invariant 4-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+Λ(1520) final state are found. |
