Searching for femtoscopic signatures of the D D ¯ ( I = 0 ), X(3700), bound state

Type: article

Abstract: The femtoscopic D D ¯ correlation functions are investigated to predict the signature of the not-yet-established X ( 3700 ) state. Here it is interpreted as a bound state generated by solving the coupled-channel Bethe-Salpeter equations with the local hidden-gauge formalism. We prospect how the relevant properties and observables characterizing this state—like the pole position, scattering lengths and compositeness—might be affected by the variation of the parameters of the model. The amplitudes are then used as input into the momentum correlation functions of the D 0 D ¯ 0 and D + D − pairs. We discuss how their behaviors encode the features of the X ( 3700 ) state.
