    abstract = "We measure exclusive pi(+)pi(-) production in proton-antiproton
collisions at center-of-mass energies root s = 0.9 and 1.96 TeV in the
Collider Detector at Fermilab. We select events with two oppositely
charged particles, assumed to be pions, with pseudorapidity vertical bar
eta vertical bar < 1.3 and with no other particles detected in vertical
bar eta vertical bar < 5.9. We require the pi(+)pi(-) system to have
rapidity vertical bar y vertical bar < 1.0. The production mechanism of
these events is expected to be dominated by double pomeron exchange,
which constrains the quantum numbers of the central state. The data are
potentially valuable for isoscalar meson spectroscopy and for
understanding the pomeron in a region of transition between
nonperturbative and perturbative quantum chromodynamics. The data extend
up to dipion mass M(pi(+)pi(-)) = 5000 MeV/c(2) and show resonance
structures attributed to f(0) and f(2)(1270) mesons. From the pi(+)pi(-)
and K+K- spectra, we place upper limits on exclusive chi(c0)(3415)
production."
