We present an updated study of charm mixing and the relative strong phase between doubly Cabibbo-suppressed D0 --> K+pi- and Cabibbo-favored D0bar --> K+pi- decay amplitudes using 3 x 10^6 quantum-correlated D0D0bar pairs from 818 pb^-1 of…

We present a preliminary measurement of the CP asymmetry in singly Cabibbo-suppressed D+ -> K-K+\pi+ decays and in the resonant decays D+ -> \phi \pi+ and D+ -> K*0 K+. We use a data sample of 79.9 fb^{-1} recorded by the BABAR detector.…

A study of charm mixing and CP violation in $D^0\to K^\pm\pi^\mp\pi^\pm\pi^\mp$ decays is performed using data collected by the LHCb experiment in proton-proton collisions from 2015 to 2018, corresponding to an integrated luminosity of…

We report on the first observation of $D_1\to D\pi^+\pi^-$ decays (where the contribution from the dominant known $D_1 \to D^* \pi$ decay mode is excluded) in the $B\to D_1\pi$ decays. The observation is based on $15.2\times 10^7 B\bar{B}$…
