Signatures of Odd-Parity $s$ -wave $Ξ^{*}$ States in Femtoscopic Correlation Functions

Jia-Xin Lin, Pablo Encarnación, Miguel Albaladejo +1

We investigate the $Ξ^{*}$ resonances within the molecular picture, where these states are dynamically generated as poles in the unitarized scattering amplitudes arising from the cou…

Spectroscopic and femtoscopic insights into vector-baryon interactions in the strangeness $- 1$ sector

P. Encarnación, M. Albaladejo, A. Feijoo +1

We revisit the strangeness $- 1$ sector of the interaction between vector mesons of the $ρ -$ nonet and $1/ 2^{+}$ ground state baryons ( $V B$ ), within the unitary coupled-channel hidden…

Testing the nature of the $Σ^{*} (1430)$

Jia-Xin Lin, Jing Song, Miguel Albaladejo +2

We study the feasibility of having the $Σ^{*} (1430)$ state, predicted within the chiral unitary approach and recently reported by the Belle Collaboration, as corresponding to a state…

Correlation function for the $p f_{1} (1285)$ interaction

Pablo Encarnación, Albert Feijoo, Eulogio Oset

We have addressed here the problem of calculating the correlation function of a stable particle with a resonance, in particular one resonance that qualifies as a molecular state of…
