    "abstract": "New SAPHIR p(gamma,K+)Lambda total cross section data show a resonance\nstructure at a total c.m. energy around 1900 MeV. We investigate this feature\nwith an isobar model and find that the structure can be well explained by\nincluding a new D_{13} resonance at 1895 MeV. Such a state has been predicted\nby a relativistic quark model at 1960 MeV with significant gamma-N and K-Lambda\nbranching ratios. We demonstrate how the measurement of single and double\npolarization observables can be used to obtain additional information on this\nresonance. Using recent (e,e\u0027K+) JLab data from Hall C we extract the\nelectromagnetic form factors of this state.",
