Determination of <(pi pi)I=2/ohm 7,8/K0 > in the chiral limit
Weak matrix elements no cover dispersion
2014/12/22
We reconsider the dispersive evaluation of the weak matrix elements h()I=2|Q7,8|K0i in the chiral limit. The perturbative matching is accomplished fully within the scheme dependence used in the two ...
K ->pi pi electroweak penguins in the chiral limit
Dispersion electroweak penguin matrix element chiral limit
2014/12/20
We report on dispersive and finite energy sum rule analyses of the electroweak penguin matrix elements left angle bracket(ππ)2|Q7,8|K0right-pointing angle bracket in the chiral limit. We accomplish th...
Precision Measurement of CP Violation in D0->pi+pi- at CDF
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.
Chiral dynamics predictions for eta' -> eta pi pi
Chiral dynamics predictions eta' -> eta pi pi
2011/1/6
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...
We present a Dalitz plot analysis of B- --> D+ pi- pi- decays, based on a sample of about 383 million Y(4S) --> BBbar decays collected by the BaBar detector at the PEP-II asymmetric-energy B Factory a...
Study of the D0 --> pi+ pi- pi0 decay at BABAR
Dipartimento di Fisica Sapienza Universit`a di Roma and Istituto Nazionale di Fisica Nucleare
2010/3/15
The Dalitz-plot of the Decay D0 --> pi+ pi- pi0 measured by the BABAR Collaboration shows the structure of a final state having quantum numbers IG JPC = 0- 0--. An isospin analysis of the Daliz-plot f...
