The magnetic moment of the $$Z_c(3900)$$ Zc(3900) as an axialvector tetraquark state with QCD sum rules
Abstract In this article, we assign the $$Z_c^\pm (3900)$$ Zc±(3900) to be the diquark-antidiquark type axialvector tetraquark state, study its magnetic moment with the QCD sum rules in the external weak electromagnetic field by carrying out the operator product expansion up to the vacuum condensate...
