abstract
The $D_s(2320)$ state recently observed by BaBar in the $D_s^+\pi^0$ channel may be the first of a host of $cq\bar q\bar q$ four-quark states. We give a phenomenological account of the masses and decay modes. The isosinglet $D_s(2320)$ state is the only narrow one, dominated by the observed isospin violating decay and less than $\sim$ 100 keV in width. All other states are expected to decay hadronically. Notable resonances are in doubly charged $D_s^+\pi^+$, $D^+K^+$, wrong pairing $D^+K^-$, and also $D_s^+K^-$, $D\eta$ channels. We propose B decays as searching ground for such 4-quark states, which recoil against $\bar D^{(*)}$ meson from B decay, or $\pi^+$ $\bar D^{(*)}$, $\bar K$ mesons from $\bar B$ decay. Exotic $qc\bar c\bar q$ charmonia could also be produced, and may be behind the slow $J/\psi$ bump in inclusive $B\to J/\psi+X$ decay.

Revealing the $D_0^*(2300)$ two-pole structure from lattice data and the SU(3) limit
Lattice data analysis with UChPT finds two I=1/2 poles at physical point with positions 2094-i111 MeV and 2463-i108 MeV; lower pole splits like the sigma on ms=const trajectory and links to 3-bar, higher pole links to...

QCD Sum Rule Analysis of Triply Heavy $(Q\bar{Q})(Q\bar{q})$ Tetraquark States with $J^P=0^{\pm}$
QCD sum rule analysis predicts four (c cbar)(c qbar) tetraquark candidates with J^P=0+/- (4.76, 5.00, 5.04 and 5.37 GeV) and (b bbar)(b qbar) states near 13.8 to 14.2 GeV, with some expected to be narrow.

Singly heavy tetraquarks
A hybrid quark model with gluon and meson exchange predicts that LHCb's T-c̄s̄0(2870) and T-cs̄0(2900) are compact tetraquarks, and that Ds0(2317), Ds1(2460), Tbs(5568), and Tcs(2327) are not.

The $B^{+(0)} \to \bar D^{0(-)} D^{*}_{s0}(2317)^+$ decays and the molecular structure of $D^*_{s0}(2317)$
Using B→D D K data and a two-parameter model, the authors derive B→D D*_s0(2317) branching fractions that agree with experiment within errors, supporting a sizable DK molecular component of D*_s0(2317).

Investigating triply heavy tetraquark states through QCD sum rules
QCD sum rules with condensates up to dimension 9 predict triply heavy tetraquark masses of 5.4 to 6.2 GeV for charm systems and 14.9 to 15.7 GeV for bottom systems.

A Phenomenological Study of Semileptonic $B^+$ and $B_s^0$ Decays into Axial-Vector Mesons $\big(D_1(2420),\, D_1^\prime(2430),\, D_{s1}(2460),\, \text{and } D_{s1}^\prime(2536)\big)$ within the Standard Model
Semileptonic B to axial-vector meson decays are studied as functions of the mixing angle θ_D1 using covariant light-front quark model form factors, producing predictions for branching ratios, forward-backward asymmetr...

Unquenched Charmonium and Beyond
This Lanzhou-group review argues that coupled-channel (unquenched) effects, not exotic constituents, are the common thread explaining charmonium anomalies from the rho-pi puzzle to the Y-problem states.
