The Compact X and Z and their Invisible Molecular Partners
A. Carducci, B. Grinstein, D. Germani +1
We propose a model explaining the strong isospin violations observed in X(3872) decays. The X is assumed to be a compact isosinglet tetraquark and its charged partners to form an i…
A short review on the compositeness of the
Angelo Esposito, Alfredo Glioti, Davide Germani +1
The could be a shallow bound state, a compact four-quark state, or a partially composite particle, i.e. a superposition of the two. We will review how these h…
Tetraquarks in the Born-Oppenheimer approximation
Davide Germani, Benjamin Grinstein, Antonio Davide Polosa
The conventional loosely bound molecule interpretation of the is not compatible with the recent LHCb experimental measurement of the ratio of branching fractions $\mathca…
On the Atomki nuclear anomaly after the MEG-II result
Daniele Barducci, Davide Germani, Marco Nardecchia +2
Recent experimental results from the Atomki collaboration have reported the observation of anomalous effects in Beryllium, Helium and Carbon nuclear transitions that could hint at…
