Abstract

In the reaction

\bar{p} p (n) \to \bar{p} p π^{+} π^{-} (n)

at 2.8 GeV/c, enhancements in the mass spectra of

\bar{p} π^{-} π^{+}

and

p π^{-} π^{+}

have been observed near 1400 MeV. Analysis indicates that these enhancements cannot be adequately explained as kinematic reflections of

N^{*} (1238)

and/or

{\bar{N}}^{*} (1238)

production.
