Possible Existence of a New Y Resonance at 1930 MeV

A new resonant wave with unknown isospin and $J^P={\frac{7}{2}}^{-}$ (${\frac{9}{2}}^{-}$ not completely excluded) is found to be necessary in order to explain the energy dependence of the higher Legendre polynomial coefficients ($A_6$, $A_7$, and $A_8$) in the expansion of the $K^{-}p$ elastic scattering differential cross section between 1937 and 1991 MeV. Assignment of this tentative resonance to a ${\frac{7}{2}}^{-}$ octet with the known $N\left(2190\right)\mathrm{}$ and $\Lambda \mathrm{}\left(2100\right)\mathrm{}$ is found to be reasonably good.
