In this article, we assume that there exist the pseudoscalar D■s0*(2317) and D*■s1*(2460) molecular states Z1,2 and construct the color singlet-singlet molecule-type interpolating currents to study their masses with...

In order to investigate the possibility of the recently observed X(5568) being a 0+ tetraquark state, we make an improvement to the study of the related various configuration states in the framework of the QCD sum ...

The lowest dimension three-gluon currents that couple to the exotic 0±−glueballs have been constructed using the helicity formalism.Based on the constructed currents,we obtain new QCD sum rules(SRs)that have been use...

In the present paper, we investigate the kaon twist-3 distribution amplitudes (DAs)Cp within the QCD background field approach. The SUf (3)-breaking effects are studied in detail under a systematical way, especiaJ...

In this work, we calculate the mass spectrum of doubly heavy baryons with the diquaxk model in terms of the QCD sum rules. The interpolating currents are composed of a heavy diquaxk field and a light quark field. Cont...
A convenient method is presented to compute the moments of the distribution amplitude for pion and a possible model form is proposed to fit the experimental data.
