“…Recently Belle collaboration reported their high precision measurement of bottomonium mass: M[Υ(5S)] =10.87 GeV [9]. If the molecular states B * B * with I(J P ) = 1(0 + ) really exist, it could be observed in final state Υ(1S)ρ at the Belle, BaBar, LHC and other collaborations.…”

“…Bondar et al also discussed the heavy quark spin structure of the Z b (10610) and Z b (10650) assuming that these are molecular state B * B and B * B * [8]. By considering the contribution from the intermediate Z b (10610) and Z b (10650) states to the Υ(5S) → Υ(2S)π + π − decay process, the anomalous Υ(2S)π + π − production near the peak of Υ(5S) at √ s = 10.87 GeV [9], observed by Belle collaboration, can be explained naturally [10]. The possibility of Z b (10610) and Z b (10650) being tetraquark states are discussed by the authors of Ref [11,12].…”

Abstract. Motivated by the two charged bottomonium-like resonances Z b (10610) and Z b (10650) newly observed by the Belle collaboration, the possible molecular states composed of a pair of heavy mesons, BB, BB * , B * B * , B sB , etc (in S-wave), are investigated in the framework of chiral quark models by the Gaussian expansion method. The bound states BB * and B * B * with quantum numbers I(J P C ) = 1(1 +− ), which are good candidates for the Z b (10610) and Z b (10650) respectively, are obtained. Other three bound states BB * with I(J P C ) = 0(1 ++ ), B * B * with I(J P C ) = 1(0 ++ ), 0(2 ++ ) are predicted. These states may be observed in open-bottom or hiddenbottom decay channel of highly excited Υ. When extending directly the quark model to the hidden color channel of the multi-quark system, more deeply bound states are found. Future experimental search of those states will cast doubt on the validity of applying the chiral constituent quark model to the hidden color channel directly.

“…In 2008 Belle reported [20] anomalously large (by two orders of magnitude) branching ratios for the decays Υ(5S ) → Υ(mS )π + π − , m = 1, 2. In [21] we suggested that the enhancement is due to an intermediate state of a tetraquark T¯b b = (bbud) and a pion, mediating the two-step process…”

“…Consequently, in the charm system the I=1 state is expected to be well above the D * D threshold and the I=0 X(3872) is at the threshold. 1 In the bottom system the attraction due to π exchange is essentially the same, but the kinetic energy is much smaller by a factor of ∼m(B)/m(D)≈2.8 . Therefore the net binding is much stronger than in the charm system.…”

Abstract. During the last three years strong experimental evidence from B and charm factories has been accumulating for the existence of exotic hadronic quarkonia, narrow resonances which cannot be made from a quark and an antiquark. Their masses and decay modes show that they contain a heavy quark-antiquark pair, but their quantum numbers are such that they must also contain a light quark-antiquark pair. The main theoretical challenge has been to determine the nature of these resonances. The main possibilities are that they are either "genuine tetraquarks", i.e. two quarks and two antiquarks within one confinement volume, or "hadronic molecules" of two heavy-light mesons. In the last few months there is more and more evidence in favor of the latter. In addition, there exist narrow resonances such as X(3872) which are not exotic but are closely related to the exotic states. Most likely such states are a mixture of hadronic molecules and excited quarkonia. I discuss the experimental data and its interpretation and provide fairly precise predictions for masses and quantum numbers of the additional exotic states which are naturally expected in the molecular picture but have yet to be observed. In addition, I provide arguments in favor of the existence of an even more exotic state -a hypothetical deuteron-like bound state of two heavy baryons. I also consider "baryon-like" states QQ qq , which if found will be direct evidence not just for near-threshold binding of two heavy mesons, but for genuine tetraquarks with novel color networks. I also stress the importance of experimental search for doubly-heavy baryons which are intimately connected with doubly heavy exotics. First observation of manifestly exotic hadronsIn The attraction due to π exchange is 3 times weaker in the I=1 channel than in the I= 0 channel. Consequently, in the charm system the I=1 state is expected to be well above the D * D threshold and the I=0 X(3872) is at the
