We report a measurement of the direct CP violation asymmetry parameter A(g) in charged kaon decays K+/- -> pi(+/-)pi(+)pi(-) by the NA48/2 experiment at the CERN SPS. The experiment has been designed not to be limited by systematics in the asymmetry measurement. Using 1.67 x 10(9) such decays collected during the 2003 run, the charge asymmetry in the Dalitz plot linear slope parameter g has been measured to be A(g) = (1.7 +/- 2.9) x 10(-4). The precision of the result is limited by the statistics used. (c) 2006 Elsevier B.V. All rights reserved.

Abstract
We report a measurement of the direct CP violation asymmetry parameter A(g) in charged kaon decays K+/- -> pi(+/-)pi(+)pi(-) by the NA48/2 experiment at the CERN SPS. The experiment has been designed not to be limited by systematics in the asymmetry measurement. Using 1.67 x 10(9) such decays collected during the 2003 run, the charge asymmetry in the Dalitz plot linear slope parameter g has been measured to be A(g) = (1.7 +/- 2.9) x 10(-4). The precision of the result is limited by the statistics used. (c) 2006 Elsevier B.V. All rights reserved.File in questo prodotto:
