利用LHCb探测器记录的碰撞数据样本，研究了三体强子无粲衰变的时间积分无标记Dalitz图，对应于积分光度.衰变振幅用等压线模型描述。测量了等压线振幅对衰变分支分数的相对贡献和特定风味振幅的不对称性。共轭率和衰变率之间的不对称性被确定为。
The time-integrated untagged Dalitz plot of the three-body hadronic charmless decayis studied using acollision data sample recorded with the LHCb detector, corresponding to an integrated luminosity of. The decay amplitude is described with an isobar model. Relative contributions of the isobar amplitudes to thedecay branching fraction andasymmetries of the flavor-specific amplitudes are measured. Theasymmetry between the conjugateanddecay rates is determined to be.
