Molecular Interpretation of the $P_c(4440)$ and $P_c(4457)$ States
hep-ph 2019-08 conditional novelty 7.0 of 10

The paper predicts Pc(4440) has J^P = 3/2- and Pc(4457) has J^P = 1/2+ in a pion-exchange coupled-channel model without short-range terms.

hep-ph 2015-09 conditional novelty 6.0 of 10

The Pc(4380)+ and Pc(4450)+ states are best discriminated by searching for neutral partners, isospin-3/2 partners, and decay ratios that differ sharply across meson-baryon interpretations.
X(3872) and Y(4140) using diquark-antidiquark operators with lattice QCD
hep-lat 2015-03 conditional novelty 6.0 of 10

In a two-flavor lattice simulation at pion mass 266 MeV, a candidate for the exotic X(3872) appears just below the D Dbar* threshold only when a charm-anticharm interpolator is present, and no Y(4140) or charged X(387...
Power Counting and Perturbative One Pion Exchange in Heavy Meson Molecules
hep-ph 2012-04 conditional novelty 6.0 of 10

Tensor one-pion exchange in heavy meson molecules is perturbative below critical momenta of roughly 200 to 700 MeV, leaving a contact-range effective field theory at leading order.
Couplings in coupled channels versus wave functions: application to the X(3872) resonance
hep-ph 2009-11 accept novelty 6.0 of 10

In coupled-channel bound states, channel couplings from scattering-matrix residues track the wave function at the origin, not the channel probability, which explains the X(3872)'s near-isospin-zero character.

hep-ph 2003-11 accept novelty 6.0 of 10

The X(3870) resonance is identified as a shallow D0 D*0bar molecule whose narrow width, suppressed production, and decay pattern all follow from one unnaturally large scattering length.

Amplitude analysis and the nature of the Zc(3900)
hep-ph 2016-12 conditional novelty 5.0 of 10

Fitting four competing models to the same BESIII Zc(3900) datasets yields statistically indistinguishable fit quality, so present data cannot separate a resonance from a virtual state or a triangle-singularity artifact.
Coupled-channel analysis of the possible $D^{(*)}D^{(*)}$, $\bar{B}^{(*)}\bar{B}^{(*)}$ and $D^{(*)}\bar{B}^{(*)}$ molecular states
hep-ph 2012-11 conditional novelty 5.0 of 10

Within a one-boson-exchange model with a per-state tuned cutoff, several doubly-heavy meson pairs bind into deuteron-like molecules, but which states count as bound is set by the cutoff choice rather than predicted.
Is X(3872) a molecule?
hep-ph 2008-05 conditional novelty 5.0 of 10

A careful rederivation of pion exchange between charmed and bottom mesons finds the X(3872) can bind as a molecule, but only for cutoff values above roughly 960 MeV, a parameter the paper cannot pin down.

D0 observes 522 X(3872) -> J/psi pi+pi- candidates in 230 pb^-1 of p-pbar data and measures its mass difference from the J/psi as 774.9 +/- 3.1 (stat) +/- 3.0 (syst) MeV.

hep-ph 2004-02 conditional novelty 5.0 of 10

The X(3872) is a deuteron-like D anti-D* molecule whose large isospin breaking, driven by the 8 MeV charged-neutral D mass splitting, permits J/psi rho decay while forbidding J/psi sigma.
Short Range Structure in the X(3872)
hep-ph 2003-11 conditional novelty 5.0 of 10

The X(3872) is modeled as a weakly bound D0 anti-D*0 molecule whose binding comes from pion exchange plus mixing with omega J/psi and rho J/psi, yielding a predicted mass of 3.872 GeV and a table of decay branching ratios.

There have been a number of hypotheses for its nature including it being a $D^*0 D̅^0$ molecule [ref] , a hybrid [ref] , a tetraquark [ref] , and even a conventional charmonium [ref] , but there seems to be no consensus on which the correct interpretation of this state is.

Its minimal content would be $cc̅ qq̅$, with $q$ either $u$- or $d$-quark, and the additional quarks could be gather together by color forces forming a new kind of hadron, which is basically classified into a compact tetraquark of hadronic size [ref] or a hadron molecule with an extension larger than $1 fm$ [ref] .
