Parametrically narrow tetraquark states containing one heavy quark and one heavy antiquark
Yiming Cai, Thomas Cohen
This paper focuses on tetraquarks containing one heavy quark and one heavy antiquark in the formal limit where the heavy quark masses go to infinity. It extends the theoretical fra…

Narrow exotic hadrons in the heavy quark limit of QCD
Yiming Cai, Thomas Cohen
This paper focuses on tetraquarks containing two heavy quarks in the formal limit where the heavy quark masses are taken to be arbitrarily large. There are well-established model-i…
