2011/1/5
We present a study of the P-wave spin -triplet charmonium cJ decays (J = 0, 1, 2) into 0000.The analysis is based on 106 million ′ decays recorded with the BESIII detector at the BEPCII electron...

Precision Measurement CP Violation D0->pi+pi- at CDF
2011/1/4
We report a preliminary measurement of the CP violating asymmetry in D0 →p+p− using approximately 215·000 decays reconstructed in about 5.94 fb−1 of CDF data.
New measurement of the K+- --> pi+-mu+mu- decay
New measurement he K+- --> pi+-mu+mu- decay

A sample of 3120 K± → π±μ+μ− decay candidates with (3.3 ± 0.7)% background contamination has been collected by the NA48/2 experiment at the CERN SPS, allowing a detailed study of the decay prope...
We perform a Dalitz plot analysis of about 100, 000 D+ s decays to K+K−+ and measure the
complex amplitudes of the intermediate resonances which contribute to this decay mode.

The Dalitz plot distribution of the ′ → decays is analyzed in the frameworks of
large-NC Chiral Perturbation Theory and Resonance Chiral Theory. The size of the ′
branching ratios is thus sati...
