Measurement of exclusive pion pair production in proton–proton collisions at √s=7TeV with the ATLAS detector

The exclusive production of pion pairs in the process pp -> pp pi(+)pi(-) has been measured at root s = 7TeV with the ATLAS detector at the LHC, using 80 mu b(-1) of low-luminosity data. The pion pairs were detected in the ATLAS central detector while out
