An analysis of the Lattice QCD spectra for $D^*_{s0}(2317)$ and $D^*_{s1}(2460)$

TL;DR

This paper reanalyzes lattice QCD data using effective field theories to confirm the existence of $D^*_{s0}(2317)$ and $D^*_{s1}(2460)$ states, highlighting their strong meson-meson components.

Contribution

It provides a novel reanalysis of lattice data with effective field theories, confirming the states and quantifying their meson-meson contributions.

Findings

Confirmed the bound states $D^*_{s0}(2317)$ and $D^*_{s1}(2460)$ on lattice data.

Determined the dominant $KD$ and $KD^*$ components in the states.

Indicated a large meson-meson component in both states.

Abstract

In this talk I present the results obtained using effective field theories in a finite volume from a reanalysis of lattice data on the $KD^{(*)}$ systems, where bound states of $KD$ and $KD^*$ are found and associated with the states $D^*_{s0}(2317)$ and $D^*_{s1}(2460)$, respectively. We confirm the presence of such states on the lattice data and determine the weight of the $KD$ channel in the wave function of $D^*_{s0}(2317)$ and that of $KD^*$ in the wave function of $D^*_{s1}(2460)$. Our results indicate a large meson-meson component in both cases.
