We use a data sample of 468     fb − 1 collected by the BABAR experiment at the PEP-II B factory at SLAC, and consider pairs of charged pions produced in opposite hemispheres of hadronic events. We observe clear asymmetries in the distributions of the azimuthal angles in two distinct reference frames. We study the dependence of the asymmetry on several kinematic variables, finding that it increases with increasing pion momentum and momentum transverse to the analysis axis, and with increasing angle between the thrust and beam axis.26 p.application/pdfeng(c) American Physical Society, 2014Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6464502019-04-02info:eu-repo/semantics/openAccess
