Substructure of Multiquark Hadrons (Snowmass 2021 White Paper)
Nora Brambilla, Hua-Xing Chen, Angelo Esposito +27
In recent years there has been a rapidly growing body of experimental evidence for existence of exotic, multiquark hadrons, i.e. mesons which contain additional quarks, beyond the…

Long-range neutrinoless double beta decay mechanisms
Jenni Kotila, Jacopo Ferretti, Francesco Iachello
Understanding the origin of lepton number violation is one of the fundamental questions in particle physics today. Neutrinoless double beta decay provides a way in which this viola…
Quark structure of the , and states
