Multibody decay analyses -- a new phenomenological model for meson-meson subamplitudes
P. C. Magalhães, A. C. dos Reis, M. R. Robilotta
Meson-meson amplitudes are important on their own and also play key roles in analyses of heavy-meson and tau decays. In this work we propose a new phenomenological model suited to…
Multi-Meson Model for the decay amplitude
R. T. Aoude, P. C. Magalhães, A. C. dos Reis +1
We propose a novel approach to describe the decay amplitude, based on chiral effective Lagrangians, which can be used to extract information about sca…
CP Asymmetries in Three-Body Final States in Charged Decays & CPT Invariance
I. Bediaga, I. I. Bigi, J. Miranda +1
The study of local \cp \ asymmetry in Dalitz plots of charm (& beauty) decays gives us more information about the underlying dynamics than the ratio between total rates. In this pa…
D+ -> K- pi+ pi+ : heavy meson decays and final state interactions
P. C. Magalhães, M. R. Robilotta, K. S. F. F. Guimarães +5
We show that final state interactions are important in shaping Dalitz plots for the decay $D^+ \rar K^- \p^+ \p^+$. The theoretical treatment of this reaction requires a blend of s…
Second Generation of 'Miranda Procedure' for CP Violation in Dalitz Studies of B (\& D \& τ) Decays
I. Bediaga, I. I. Bigi, A. Gomes +4
The `Miranda Procedure' proposed for analyzing Dalitz plots for CP asymmetries in charged B and D decays in a model-independent manner is extended and refined. The complexity of CK…
Three-body FSIs in D+ ---> K- pi+ pi+
Patrícia C. Magalhães, M. R. Robilotta, K. S. F. F. Guimarães +4
We stress the importance of three-body final state interactions in $D^+ \to K^- \p^+ \p^+$. The basic building block is the amplitude with parameters determined by a fit to el…
