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.
