First Observation of the $Λ(1405)$ Line Shape in Electroproduction    [PDF]

H. Y. Lu, R. A. Schumacher, CLAS Collaboration

We report the first observation of the line shape of the $\Lambda(1405)$ from electroproduction, and show that it is not a simple Breit-Wigner resonance. Electroproduction of $K^+ \Lambda(1405)$ off the proton was studied by using data from CLAS at Jefferson Lab in the range $1.0View original: http://arxiv.org/abs/1307.4411
