BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using 20.3~fb of annihilation data collected at a center-of-mass energy of 3.773~GeV with the BESIII detector, we report the first observation of the semileptonic d…

We perform a measurement of time-dependent violation parameters in decays using a dataset of approximately and $521 \times 10…
Search for the decays and at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using a 10.9 fb data sample collected by the BESIII detector at center-of-mass energies from 4.16 to 4.34 GeV, we search for the charmless decays $X(3872) \to K_{S}^{0}K^{\p…
