Tetraquarks made of sufficiently unequal-mass heavy quarks are bound in QCD
Benoît Assi, Michael L. Wagman
Tetraquarks, bound states composed of two quarks and two antiquarks, have been the subject of intense study but are challenging to understand from first principles. We apply variat…

A model independent description of decays
Erik J. Gustafson, Florian Herren, Ruth S. Van de Water +2
We introduce a new parameterization of form factors using a partial-wave expansion and derive bounds on the series coefficients using analyticity and uni…

A variational study of two-nucleon systems with lattice QCD
Saman Amarasinghe, Riyadh Baghdadi, Zohreh Davoudi +6
The low-energy spectrum and scattering of two-nucleon systems are studied with lattice quantum chromodynamics using a variational approach. A wide range of interpolating operators…
