“…These three sources of strong phases are known to give clear signatures in the Dalitz plane [13,14]. The shortdistance direct CP violation is proportional to the difference of the magnitude between the positive and negative amplitudes of the resonance, and is therefore proportional to the square of the Breit-Wigner propagator associated with the resonance.…”

“…The remaining two sources are related to longdistance effects involving hadron-hadron interactions in the final state. Interference between intermediate states of the decay can introduce large strong-phase differences, and therefore induce local asymmetries in the phase space [9,[13][14][15][16]. Another mechanism is final-state KK ↔ ππ rescattering, which can occur between decay channels having the same flavor quantum numbers [7][8][9][10].…”

π − are reconstructed using data, corresponding to an integrated luminosity of 3.0 fb −1 , collected by the LHCb detector. The inclusive CP asymmetries of these modes are measured to bewhere the first uncertainty is statistical, the second systematic, and the third is due to the CP asymmetry of the B AE → J=ψK AE reference mode. The distributions of these asymmetries are also studied as functions of position in the Dalitz plot and suggest contributions from rescattering and resonance interference processes.

“…The cleanest method requires measurements from the B 0 → K + π − π 0 and B 0 → K 0 S π + π − Dalitz plots [1146][1147][1148]. Other methods also use B + → K 0 S π + π 0 [1146], 1149], and B s → K + π − π 0 and B s → K 0 S π + π − [1150].…”

Flavor physics in the quark sector

In the past decade, one of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor. In this time frame, measurements and the theoretical interpretation of their results have advanced tremendously. A much broader understanding of flavor particles has been achieved; apart from their masses and quantum numbers, there now exist detailed measurements of the characteristics of their interactions allowing stringent tests of Standard Model predictions. Among the most interesting phenomena of flavor physics is the violation of the CP symmetry that has been subtle and difficult to explore. In the past, observations of CP violation were confined to neutral K mesons, but since the early 1990s, a large number of CP-violating processes have been studied in detail in neutral B mesons. In parallel, measurements of the couplings of the heavy quarks and the dynamics for their decays in large samples of K, D, and B mesons have been greatly improved in accuracy and the results are being used as probes in the search for deviations from the Standard Model. In the near future, there will be a transition from the current to a new generation of experiments; thus a review of the status of quark flavor physics is timely. This report is the result of the work of physicists attending the 5th CKM workshop, hosted by the University of Rome "La Sapienza", September 9-13, 2008. It summarizes the results of the current generation of experiments that are about to be completed and it confronts these results with the theoretical understanding of the field which has greatly improved in the past decade.

We study the localized direct CP violation in the hadronic decays B ± → ρ 0 (ω)π ± → π + π − π ± , including the effect caused by an interesting mechanism involving the charge symmetry violating mixing between ρ 0 and ω. We calculate the localized integrated direct CP violation when the low invariant mass ofFor the five models of form factors investigated, we find that the localized integrated direct CP violation varies from −0.0752 to −0.0290 in the ranges of parameters in our model when 0.750 < m(π + π − ) low < 0.800 GeV. This result, especially the sign, agrees with the experimental data and is independent of the form factor models. The new experimental data shows that the signs of the localized integrated CP asymmetries in the regions 0.470 < m(π + π − ) low < 0.770 and 0.770 < m(π + π − ) low < 0.920 GeV are positive and negative, respectively. We find that ρ-ω mixing makes the localized integrated CP asymmetry move toward the negative direction, and therefore contributes to the sign change in those two regions. This behavior is also independent of the form factor models. We also calculate the localized integrated direct CP violating asymmetries in the regions 0.470 < m(π + π − ) low < 0.770, 0.770 < m(π + π − ) low < 0.920 and the whole region 0.470 < m(π + π − ) low < 0.920 GeV and find that they agree with the experimental data in some models of the form factors.
