Title: Central Exclusive $$\pi^{+}\pi^{-}$$ Production in $$p\bar{p}$$ Collisions at $$\sqrt{s} = 0.9$$ and 1.96 TeV at the Tevatron

Abstract

Exclusive $$\pi^{+}\pi^{-}$$ production in proton-antiproton collisions at $$\sqrt{s} = 0.9$$ and 1.96 TeV in the Collider Detector at Fermilab has been measured. We selected events with exactly two particles with opposite charge, in $$|\eta|<1.3$$, with no other particles detected in $$|\eta| < 5.9$$. We require the central $$\pi^{+}\pi^{-}$$ to have rapidity $|y|<1$. Since these events are dominated by double pomeron exchange, the quantum numbers of the central state are constrained. The data show resonance structures attributed to the $$f_0$$ and $$f_2$$ mesons.
