abstract

We investigate $DD^*$ and $D\bar{D}^*$ momentum correlations in high-energy collisions to elucidate the nature of $T_{cc}$ and $X(3872)$ exotic hadrons. Single range Gaussian potentials with the channel couplings to the isospin partners are constructed based on the empirical data. The momentum correlation functions of the $D^0D^{*+}$, $D^+D^{*0}$, $D^0\bar{D}^{*0}$, and $D^+D^{*-}$ pairs are computed with including the coupled-channel effects. We discuss how the nature of the exotic states are reflected in the behaviors of the correlation results.

  1. A femtoscopic tale of two $C$-parities: the $Z_c(3900)$ and the isovector partner of the $X(3872)$

    hep-ph 2026-08 conditional novelty 7.0 of 10

    Femtoscopic correlations of charged charm meson pairs mix C-odd and C-even interactions, giving a new experimental probe of the predicted W_c1 state and correcting earlier predictions.

  2. Quantum interference effects enhanced in $\pi^+p$ femtoscopic correlation functions

    hep-ph 2026-07 conditional novelty 7.0 of 10

    The π⁺p correlation peak near 140 MeV/c arises from quantum interference of incident and scattered waves, while the Δ decay peaks near 220 MeV/c; their m_T-dependent mix explains the ALICE peak shift.

  3. $D\bar{D}^\ast$-$\pi J/\psi$ scatterings of coupled channels for $Z_c(3900)$ channel

    hep-ph 2026-04 unverdicted novelty 6.0 of 10

    Quark-exchange interactions at short distances dominate the coupled-channel scattering amplitudes for Zc(3900) over meson exchanges in an effective hadron-quark model.

  4. Spectroscopic and femtoscopic insights into vector-baryon interactions in the strangeness $-1$ sector

    hep-ph 2025-07 conditional novelty 6.0 of 10

    The authors predict three Lambda* and two Sigma* resonances from vector-baryon interactions and provide femtoscopy correlation functions for six channels in the S=-1 sector.

  5. $KX(3872)$ interaction and correlation function

    hep-ph 2026-07 conditional novelty 5.0 of 10

    A unitarized fixed-center approximation predicts a narrow KX(3872) bound state 50 MeV below threshold and a characteristic femtoscopic correlation function.

  6. Correlation functions for $n\,\bar{D}_{s1}(2460)$ and $n\,\bar{D}_{s1}(2536)$

    hep-ph 2025-08 conditional novelty 5.0 of 10

    The neutron-D_{s1}(2460) and neutron-D_{s1}(2536) systems are predicted to have bound states, with correlation functions sensitive to the molecular structure of the D_{s1} mesons.

  7. Production mechanism of doubly charmed exotic mesons $T_{cc}$

    hep-ph 2025-07 conditional novelty 4.0 of 10

    A coupled-channel model generates the Tcc(3875)+ as an isovector DD* molecule and predicts three additional J=1 tetraquark states, including a negative-parity resonance.
