abstract
We perform a study of the $B^{*+}B^0,B^{*0}B^+$ correlation functions using an extension of the local hidden gauge approach which provides the interaction from the exchange of light vector mesons and gives rise to a bound state of these components in $I=0$ with a binding energy of about $21$~MeV. After that, we face the inverse problem of determining the low energy observables, scattering length and effective range for each channel, the possible existence of a bound state, and, if found, the couplings of such a state to each $B^{*+}B^0,B^{*0}B^+$ component as well as the molecular probabilities of each of the channels. We use the bootstrap method to determine these magnitudes and find that, with errors in the correlation function typical of present experiments, we can determine all these magnitudes with acceptable precision. In addition, the size of the source function of the experiment from where the correlation functions are measured can be also determined with a high precision.

Signatures of the $\Omega(2012)^{-}$ state in $\Xi^*\bar K$ Correlation Functions
Ω(2012) is dynamically generated as a Ξ*K–Ωη molecule; its pole produces pronounced near-threshold structures in the Ξ*0K− correlation function that can be measured at the LHC.

Nature of the newly found $\Omega(2109)$
Coupled-channel calculations in K- Ξ0, K̄0 Ξ-, K*- Ξ0 and K̄*0 Ξ- channels generate an isoscalar 1/2- resonance at 2109 MeV strongly correlated with the K̄* Ξ system.

Nature of the newly found $\Omega(2109)$
A coupled-channel calculation generates an isoscalar J^P=1/2^- Omega resonance near 2.1 GeV, dominated by Kbar*Xi, matching the newly reported Omega(2109).

Correlation functions for $n\,\bar{D}_{s1}(2460)$ and $n\,\bar{D}_{s1}(2536)$
The neutron-D_{s1}(2460) and neutron-D_{s1}(2536) systems are predicted to have bound states, with correlation functions sensitive to the molecular structure of the D_{s1} mesons.
