${{\boldsymbol \Delta}{(\sim3000 \text{ Region})}}$ Partial-Wave Analyses

We list here miscellaneous high-mass candidates for isospin-${}^{}3/2{}^{}$ resonances found in partial-wave analyses. Our 1982 edition also had a ${{\mathit \Delta}{(2850)}}$ and a ${{\mathit \Delta}{(3230)}}$. The evidence for them was deduced from total cross-section and 180$^\circ{}$ elastic cross-section measurements. The ${{\mathit \Delta}{(2850)}}$ has been resolved into the ${{\mathit \Delta}{(2750)}}{\mathit I}_{\mathrm 3,13}$ and ${{\mathit \Delta}{(2950)}}{\mathit K}_{\mathrm 3,15}$. The ${{\mathit \Delta}{(3230)}}$ is perhaps related to the ${\mathit K}_{\mathrm 3,13}$ of HENDRY 1978 and to the ${\mathit L}_{\mathrm 3,17}$ of KOCH 1980 .
