Abstract

We discuss properties of three-particle Dalitz distributions in coupled channel systems in presence of triangle singularities. The single channel case was discussed long ago where it was found that as a consequence of unitarity, effects of a triangle singularity seen in the Dalitz plot are not seen in Dalitz plot projections. In the coupled channel case we find the same is true for the sum of intensities of all interacting channels. As a result, unlike the single channel case, however, triangle singularities do remain visible in Dalitz plot projections of individual channels.

Constraints on the unitarity triangle angle $γ$ from Dalitz plot analysis of $B^{0} \to D K^{+} π^{-}$ decays

Journal Article Aaij, R. ; Abellán Beteta, C. ; Adeva, B. ; ... - Physical Review D

The first study is presented of CP violation with an amplitude analysis of the Dalitz plot of B⁰ → DK⁺π^– decays, with D → K⁺π^–, K⁺K^–, and π⁺π^–. The analysis is based on a data sample corresponding to 3.0 fb^–1 of pp collisions collected with the LHCb detector. No significant CP violation effect is seen, and constraints are placed on the angle γ of the unitarity triangle formed from elements of the Cabibbo-Kobayashi-Maskawa quark mixing matrix. Hadronic parameters associated with the B⁰ → DK*(892)⁰ decay are determined for the first time. These measurements can be used to improve the sensitivitymore »« less

Triangle singularities and XYZ quarkonium peaks

Journal Article Szczepaniak, Adam P. - Physics Letters B

We discuss analytical properties of partial waves derived from projection of a 4-legged amplitude with crossed-channel exchanges in the kinematic region of the direct channel that corresponds to the XYZ peaks in charmonium and bottomonium. We show that in general partial waves can develop anomalous branch points in the vicinity of the direct channel physical region. In a specific case, when these branch points lie on the opposite side of the unitary cut they pinch the integration contour in a dispersion relation and if the pinch happens close to threshold, the normal threshold cusp is enhanced. We show that this effect only occurs if masses of resonances in the crossed channel are in a specific, narrow range. We estimate the size of threshold enhancements originating from these anomalous singularities in reactions where themore »« less

New bounds on the Cabibbo-Kobayashi-Maskawa matrix from B{yields}K{pi}{pi} Dalitz plot analyses

Journal Article Ciuchini, M ; Pierini, M ; Silvestrini, L - Physical Review. D, Particles Fields

We present a new technique to extract information on the unitarity triangle from the study of B{yields}K{pi}{pi} Dalitz plots. Using the sensitivity of Dalitz analyses to the absolute values and the phases of decay amplitudes and isospin symmetry, we obtain a new constraint on the elements of the CKM matrix. We discuss in detail the role of electroweak penguin contributions and outline future prospects.
