Searching for signatures around 1920 MeV of a N* state of three hadron nature
/ Authors
/ Abstract
We provide a series of arguments which support the idea that the peak seen in the $ \gamma$p$ \rightarrow$K+$ \Lambda$ reaction around 1920MeV should correspond to the recently predicted state of JP = 1/2+ as a bound state of K$ \bar{{K}}$N with a mixture of a0(980)N and f0(980)N components. At the same time we propose polarization experiments in that reaction as a further test of the prediction, as well as a study of the total cross-section for $ \gamma$p$ \rightarrow$K+K-p at energies close to threshold and of dσ/dMinv for invariant masses close to the two-kaon threshold.
