Nature of the newly found
Taísa Veloso, K. P. Khemchandani, A. Martinez Torres +2
We present model calculations to reveal the nature of the newly found by the BESIII Collaboration, and show that the state has a strong correlation with the $\bar K^*(8…
Decay properties of
K. P. Khemchandani, A. Martinez Torres, H. Nagahiro +1
The nature of nucleon resonances is still being debated, while much experimental data are accumulated. In this work, we focus on the negative parity resonance which is…
Roper-like resonances with various flavor contents and their two-pion emission decays
A. J. Arifi, H. Nagahiro, A. Hosaka +1
We study the three-body decay of the newly observed bottom baryon by LHCb; . Its mass about 500 MeV above the ground state and a broad w…
Three-body decay of and determination of its spin-parity
A. J. Arifi, H. Nagahiro, A. Hosaka +1
We study three-body decays of by using effective Lagrangians in a non-relativistic framework. We consider the sequential decays through …
Three-Body Decay of and with the Inclusion of Direct Two-Pion Coupling
A. J. Arifi, H. Nagahiro, A. Hosaka
We investigate the three-body decays of and into by including a direct process going through the two-pion coupling of in addition…
Understanding the properties of and
K. P. Khemchandani, A. Martínez Torres, A. Hosaka +3
In this manuscript we discuss the results of our recent study on resonances. We have studied meson-baryon interaction with strangeness by solving scattering equations in a…
Three-Body Decay of and with Consideration of and in Intermediate States
A. J. Arifi, H. Nagahiro, A. Hosaka
Three-body decay of charmed baryons and into are studied with effective Lagrangians in which the coupling constants are extracted from the non-…
Decays of double charmed meson molecules
R. Molina, A. Hosaka, H. Nagahiro
The interaction between pseudoscalar and/or vector mesons can be studied using hidden gauge Lagrangians. In this framework, the interaction between charmed mesons has been studied.…
Decays of doubly charmed meson molecules
R. Molina, H. Nagahiro, A. Hosaka
Several observed states close to the and thresholds, as the X(3872) and some XYZ particles can be described in terms of a two-meson molecule…
Composite and elementary natures of a1(1260) meson
H. Nagahiro, K. Nawa, S. Ozaki +2
We develop a practical method to analyze the mixing structure of hadrons consisting of two components of quark-composite and hadronic composite. As an example we investigate the pr…
Decay of vector-vector resonances into and a pseudoscalar meson
R. Molina$^1$, H. Nagahiro$^2$, A. Hosaka$^3$ +1
We study the decay of dynamically generated resonances from the interaction of two vectors into a and a pseudoscalar meson. The dynamics requires anomalous terms involving vert…
Charged K* Photoproduction in a Regge model
S. Ozaki, H. Nagahiro, A. Hosaka
We investigate reaction within a Regge approach. For the gauge invariance of the scattering amplitude, we reggeize the s-channel and contact term amplitudes as we…
