Search for time-dependent 𝐶𝑃 violation in 𝐷0→𝜋+𝜋−𝜋0 decays
A measurement of time-dependent 𝐶𝑃 violation in 𝐷0→𝜋+𝜋−𝜋0 decays using a 𝑝𝑝 collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7 fb−1, is presented. The initial flavor of each 𝐷0 candidate is determined from the ch...

| 520 | |a A measurement of time-dependent violation in 0→+−0 decays using a collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7 fb−1, is presented. The initial flavor of each 0 candidate is determined from the charge of the pion produced in the *(2010)+→0+ decay. The decay 0→−+0 is used as a control channel to validate the measurement procedure. The gradient of the time-dependent asymmetry Δ in 0 →+−0 decays is measured to be Δ=(−1.3±6.3±2.4)×10−4, where the first uncertainty is statistical and the second is systematic, which is compatible with conservation. | ||
