Chiral Structure of Vector and Axial-Vector Tetraquark Currents

Understand

We investigate the chiral structure of local vector and axial-vector tetraquark currents, and study their chiral transformation properties.

• We consider the charge-conjugation parity and classify all the isovector vector and axial-vector local tetraquark currents of quantum numbers I(G)J(PC)=1(-)1(-+), I(G)J(PC)=1(+)1(--), I(G)J(PC)=1(-)1(++) and I(G)J(PC)=1(+)1(+-).
• We find that there is a one to one correspondence among them.
• Using these currents, we perform QCD sum rule analyses.
