16. Probing K-molecule interactions via correlation functions: three-body bound states in K X(3872) and K D_{s0}^*(2317)

Dr. Jing Song (Hainan University)

3/9/26 15:30

We study the interactions of a kaon with the exotic states X(3872) and D_{s0}^(2317), assumed as D\bar D^ and DK molecules with I=0. Using the fixed-center approximation to the Faddeev equations, we compute the three-body scattering amplitudes, unitarized via the Lippmann-Schwinger equation. For both systems, we find narrow resonant structures below the respective thresholds (about 50 MeV and...

13. Predicting $B^{(*)}\bar D{}^{(*)}$ states from a reanalysis of lattice QCD data

Pan-Pan Shi (IFIC)

3/9/26 16:00

We reanalyze the lattice QCD data for the isoscalar $J^P=0^+$ and $1^+$ $\bar b \bar c u d$ systems at $m_{\pi}\simeq 220$ MeV by incorporating both short- and long-range interactions. Using the interaction constrained by the lattice results, we predict a spectrum of isoscalar $B^{(*)}\bar D{}^{(*)}$ molecular states with quantum numbers $J^{P}=0^+$, $1^+$, and $2^+$. The predicted $J^P=0^+$...

6. Hyperon non-leptonic decays in relativistic ChPT with resonances

Fernando Alvarado (RUB)

3/9/26 17:00

The non-leptonic decays of hyperons constitute a longstanding theoretical problem. Motivated by recent measurements from the BESIII collaboration, we study these processes in Chiral Perturbation Theory in new Ref. [2604.00646]. We perform the first relativistic calculation of such decays and include the decuplet as an explicit degree of freedom. Moreover, the contributions from the $1/2^−$ and...

7. Revealing the puzzle of the dynamical nature of two 𝑫_𝟎^∗ states from an analysis of LQCD results

Zejian Zhuang (University of Valencia)

3/9/26 17:30

We perform an analysis of LQCD light - charmed (pseudoscalar) meson scattering data with UChPT for pion masses ranging from $m_\pi\simeq 230$~MeV till the SU(3) limit, $m_\pi\simeq 700$~MeV. We find two poles in the non-strange isospin $I=1/2$ sector that can be related to the experimental $D_0(2300)$ resonance. At the physical pion mass, the poles are located at...
