Elastic $K π$ amplitude: a simple model

P. C. Magalhães, M. R. Robilotta

We present a chiral model for the $J = 0, I = 1/2,$ elastic $K\p$ amplitude, suited to be employed in $D^+ \rar K^- \p^+ \p^+$ data analyses and valid between threshold and $1.5$ GeV.…

Decay $D^{+} \to K^{-} π^{+} π^{+}$ : chiral symmetry and scalar resonances

D. R. Boito, P. C. Magalhães, M. R. Robilotta +1

The low-energy S-wave component of the decay $D^{+} \to K^{-} π^{+} π^{+}$ is studied by means of a chiral SU(3)XSU(3) effective theory. As far as the primary vertex is concerned, we allow…

$D^+ \to K^- \p^+ \p^+ $: the low-energy sector

D. R. Boito, P. C. Magalhães, M. R. Robilotta +1

An effective $S U (3) \times S U (3)$ chiral lagrangian, which includes scalar resonances, is used to describe the process $D^+ \rar K^- \p^+ \p^+$ at low-energies. Our main result is a…

Scalar resonances: scattering and production amplitudes

D. R. Boito, M. R. Robilotta

Scattering and production amplitudes involving scalar resonances are known, according to Watson's theorem, to share the same phase $δ (s)$ . We show that, at low energies, the produc…

Pion-delta sigma-term

I. P. Cavalcante, M. R. Robilotta, J. Sa Borges +2

We use a configuration space chiral model in order to evaluate nucleon and delta sigma-terms. Analytic expressions are consistent with chiral counting rules and give rise to expect…
