Abstract

A narrow

I = \frac{1}{2}

enhancement at a mass of 1.462 ± 0.006

\frac{GeV}{c^{2}}

with a width of 0.049 ± 0.012

\frac{GeV}{c^{2}}

has been observed in

p π^{0}

and

n π^{+}

modes produced in

pp

collisions at 6.6

\frac{GeV}{c}

. The effect, having a 6-standard-deviation significance, is narrower in width than has been observed before in missing-mass-spectrometer experiments.
