Hyperfine splittings of heavy quarkonium hybrids
Joan Soto, Sandra Tomàs Valls
In the framework of the Born-Oppenheimer Effective Field Theory, the hyperfine structure of heavy quarkonium hybrids at leading order in the 1/m Q expansion is determined by two po…

Nonrelativistic effective field theory for heavy exotic hadrons
Joan Soto, Jaume Tarrús CastellÃ
We propose an effective field theory to describe hadrons with two heavy quarks without any assumption on the typical distance between the heavy quarks with respect to the typical h…
