Light scalar mesons in D^+, D_s^+ decays into three pseudoscalars
L. Maiani, A. D. Polosa, V. Riquer
In response to recent experimental findings from the BES III and LHCb collaborations concerning the decay of open charm mesons into three pseudoscalars, we present evidence suggest…

Open charm tetraquarks in broken SU(3)_F symmetry
L. Maiani, A. D. Polosa, V. Riquer
Prompted by a recent lattice QCD calculation, we review the SU(3) light quark flavor structure of charmed tetraquarks with spin-0 diquarks. Fermi statistics forces the three light…
