Type: Leading parallel Session: Hadron decays, production and interactions-3
Track: Hadron Decays, Production and Interactions
BESIII has collected 2.9 and 6.3 fb-1 of e+e- collision data samples at 3.773 and 4.178-4.226 GeV, respectively. We have performed amplitude analyses on the decays of Ds -> K+K-pi+, pi+pi+pi-, KSpi+pi0, K+K-pi+pi0, etapi+pi+pi0, and D+ -> KSK+pi0. Rich structures have been observed in these decays. We will present the results based on these analyses. In addition, we will also report observations ... More

Measurements of CP asymmetries in charmless two-body B-meson decays can provide stringent tests of the Standard Model. In multibody decays, short and long-distance dynamics along with a sizeable effective weak phase in the interference between tree and penguin amplitudes can lead to a rich structure of CP violation as a function of the phase space. We present here the latest studies of CP violatio ... More

Track: Hadron Decays, Production and Interactions
BESIII has collected 2.9 fb-1 of e+e- collision data samples at 3.773 GeV, respectively. We have observed the doubly Cabibbo-suppressed (DCS) D decay of D+ -> K+pi+pi-pi0 with a branching fraction of (1.13+-0.08+-0.03)*10^-3. We find that the DCS/CF ratio of B[D+ -> K+pi+pi-pi0]/B[D+ -> K-pi+pi-pi0], corresponding to (6.28\pm0.52)tan^4(theta_C),is significantly larger than the naive expectation. ... More

Comprehensive studies of deuteron formation in the bottomonium region have not been performed so far. We review the phenomenological models available in the literature. We find consistency among the three $\Upsilon$s, but not with data from continuum. In particular, the simplest coalescence model seems to perform better. We also report the first prediction on H-dibaryon production rate, which are ... More

The measurements of spectroscopy and decays of b-hadrons can provide valuable experimental input for QCD. The LHCb detector at the LHC is dedicated to heavy flavour physics. The large dataset and excellent detector performance give it unprecedented capability in searching for new b-hadron states and new decays of existing b-hadrons, and performing precision measurements on established modes. In th ... More
