Study of CP Violation in charm decays

Felipe Cesário Laterza Lopes, Patrícia Camargo Magalhães

The violation of the Charge-Parity (CP) symmetry is a phenomenon described by the Standard Model (SM), however, its predictions for this violation are not enough to explain the mat…

Enhanced charm CP asymmetries from final state interactions

Ignacio Bediaga, Tobias Frederico, Patricia C Magalhães

We show that final state interactions (FSI) within a CPT invariant two-channel framework can enhance the charge-parity (CP) violation difference between $D^{0} \to π^{-} π^{+}$ and $D^0\to…

Charm rescattering contribution in rare $B_{c}^{+} \to K^{+} K^{-} π^{+}$ decay

Ignacio Bediaga, Tobias Frederico, Patricia C Magalhaes

Following the experimental results from LHCb on the rare decay $B_{c}^{+} \to K^{-} K^{+} π^{+}$ , we investigate the possibility where this process is dominated by a double charm rescattering.…

Charm Penguin in $B^{\pm} \to K^{\pm} K^{+} K^{-}$ : partonic and hadronic loops

Ignacio Bediaga, Tobias Frederico, Patricia C Magalhães

Charm penguin diagrams are known to be the main contribution to charmless B decay process with strangeness variation equal to minus one, which is the case of $B^\pm \to K^\pm K^+ K…

Multi-Meson Model applied to $D^{+} \to K^{+} K^{-} K^{+}$

R. T. Aoude, P. C. Magalhães, A. C. dos Reis +1

Matrix elements of weak currents involving light multi-meson states are important in many hadronic decays of both heavy leptons and heavy mesons. In this paper we focus on the latt…

Final state interaction on $B^{+} \to π^{-} π^{+} π^{+}$

I. Bediaga, P. C. Magalhães

The large localized CP asymmetries observed by LHCb in three-body charmless decays of $B$ mesons brings new challenge for experimentalists and their traditional models to fit data.…

$D^{+} \to K^{-} π^{+} π^{+}$ - the weak vector current

P. C. Magalhães, M. R. Robilotta

Studies of D and B mesons decays into hadrons have been used to test the standard model in the last fifteen years. A heavy meson decay involves the combined effects of a primary we…

Unitarization and low-energy scattering data

Patricia C. Magalhães, Manoel R. Robilotta

A method is presented which makes considerably more transparent possible patterns behind low-energy scattering data. In particular, structures associated with resonances, such as l…

A complete model for $D^{+} \to K^{-} π^{+} π +$ S-wave

Patrícia Camargo Magalhães, Manoel Roberto Robilotta

The $D^{+} \to K^{-} π^{+} π +$ decay have been observed in LHCb collaboration with thousands of events per second from $K π$ threshold. The theoretical treatment of this decay includes a ri…

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…

Towards three-body unitarity in $D^{+} \to K^{-} π^{+} π^{+}$

P. C. Magalhães, M. R. Robilotta, K. S. F. F. Guimarães +6

We assess the importance of final state interactions in $D^+ \rar K^- \p^+ \p^+$, stressing the consistency between two- and three-body interactions. The basic building block in th…
