Mixing between the 23S1 and 13D1 Ds

    Corresponding author: ZHANG Ai-Lin,

Abstract: Mixing between the 23S1 and 13D1 Ds is studied within the 3P0 model. If mixing between these two 1- states exists, Ds1*(2700)± and DsJ*(2860)± could be interpreted as the two orthogonal mixed states with mixing angle θ≈ -80° in the case of a special β for each meson. However, in the case of a universal β for all mesons, Ds1*(2700)± could be interpreted as the mixed state of 23S1 and 13D1 with mixing angle 12° < θ < 21° but DsJ*(2860)± seems difficult to interpret as the orthogonal partner of Ds1*(2700)±.
