Hunting for tetraquarks in ultra-pheripheral heavy ion collisions
Angelo Esposito, Claudio Andrea Manzari, Alessandro Pilloni +1
Ultra-peripheral heavy ion collisions constitute an ideal setup to look for exotic hadrons because of their low event multiplicity and the possibility of an efficient background re…
From the lineshape of the to its structure
Angelo Esposito, Luciano Maiani, Alessandro Pilloni +2
From a study of the lineshape of the , the LHCb collaboration measures a sizeable negative effective range. This cannot be reconciled with a shallow bound sta…
Implementation and Optimization of the PTOLEMY Transverse Drift Electromagnetic Filter
A. Apponi, M. G. Betti, M. Borghesi +53
The PTOLEMY transverse drift filter is a new concept to enable precision analysis of the energy spectrum of electrons near the tritium beta-decay endpoint. This paper details the i…
The new resonances Z_{cs}(3985) and Z_{cs}(4003) (almost) fill two tetraquark nonets of broken SU(3)_f
Luciano Maiani, Antonio D. Polosa, Veronica Riquer
New data from BESIII and LHCb show the existence of resonances with strangeness filling multiplets of the broken SU(3)_f symmetry, with the pattern predicted by the quark model. Th…
Radiative and meson decays of in flavor SU(3)
Luciano Maiani, Antonio D. Polosa, Verónica Riquer
The charmonium-like exotic states and the less known , produced in collisions, are sources of positive parity exotic hadrons in association with photons…
