We present results on central exclusive production of π+π- in collisions at and 1960 GeV using events with two charged hadrons in the final state within the pseudorapidity region |η |≤ 1.3 and no particles in |η| > 1.3. These results open a new window into hadron spectroscopy, and may be used as benchmarks for testing relevant theoretical models.

PACS Number(s): 13.30.Eg.

Keywords: Central exclusive production, diffraction, low mass states.
