We measure γ = ( 68 ± 14 ± 4 ± 3 ) ° (modulo 180°), where the first error is statistical, the second is the experimental systematic uncertainty, and the third reflects the uncertainty in the description of the neutral D decay amplitudes. This result is inconsistent with γ = 0 (no direct C P violation) with a significance of 3.5 standard deviations.7 p.application/pdfeng(c) American Physical Society, 2010Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6019472019-06-18info:eu-repo/semantics/openAccess
