12. Correlation function for the $n \bar{D}_{s0}^*(2317)$ interaction and the issue of elastic unitarity

Natsumi Ikeno

We study the interaction between a neutron and the $\bar D_{s0}^*(2317)$ resonance and look at the amplitude below and slightly above the threshold. The $D_{s0}^*(2317)$ resonance is treated as a molecular state of the $DK$ system with isospin $I=0$. The interaction is investigated using the Fixed Center Approximation (FCA) to the Faddeev equations, where the $DK$ molecule is taken as the...

11. Hadron and Charm Physics in São Paulo: A Panoramic Perspective

Prof. Kanchan Khemchandani

This talk presents an overview of hadron physics research being carried out in São Paulo, focusing closely on the work of the group at the Federal and State University of São Paulo. We review the group's systematic application of unitarized effective field theories, three-body dynamics, and QCD sum rules to decode the non-perturbative regime. We discuss how these phenomenological results offer...

8. interaction and correlation functions of external particles with molecular states

Prof. Eulogio Oset (IFIC)

I shall report on the interaction of external particles with molecular states made from the interaction of mesons, evaluating the scattering matrix and the correlation function. In particular I shall discuss the cases:
$p f_1(1285)$, n $D^*_{s0}(2317)$, $n\,\bar{D}_{s1}(2460)$ and $n\,\bar{D}_{s1}(2536)$, $K f_1(1285)$, $K D_{s0}^*(2317)$, $\pi f_1(1285)$ and $ \eta f_1(1285)$ and ...

10. On the possible existence of a S=−3,I=1 pentaquark

Isaac Vidana (Istituto Nazionale di Fisica Nucleare)

In this exploratory work we analyze the possible existence of a strangeness $S=-3$, isospin $I=1$ pentaquark state $P_{sss}$ generated dynamically from the $\bar{K}\Xi$ interaction. We employ a unitarized scheme in coupled channels based on the chiral Lagrangian expanded up to next-to-leading order (NLO), and show that the inclusion of the NLO terms can be crucial to provide the necessary...
