DIESBURG
1987
SPEC ${{\mathit n}}{}^{}\mathrm {A}$ $\sim{}$600 GeV
1  DIESBURG 1987 is completely incompatible with the other experiments, which is surprising since it agrees with them about ${\mathit m}_{{{\mathit \Sigma}_{{c}}{(2455)}^{++}}}–{\mathit m}_{{{\mathit \Lambda}_{{c}}^{+}}}$. We go with the majority here.
