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.

“…We focus our attentions on the lowest charged states [Qq][Q ′q′ ], and therefore the orbital angular momentum between two clusters is set to 0, then parity P = +, isospin I = [31,32]. From the results, we also find that ∆E ′ of the low-spin (S = 0 or 1) tetraquark states [Qq][Q ′q′ ] are much higher, several hundreds MeVs, while ∆E ′ of the high-spin (S = 2) states are several tens of MeVs.…”

“…Other unexplained and potentially dangerous deviations from linearity were observed: Matsumura [11] and Yang [12] found frequency-dependent Young's modulus variations in Tungsten wires and Hu [13] an amplitude dependency. Both effects have also been observed in springs of gravitational wave detectors.…”

Unaccounted source of systematic errors in measurements of the Newtonian gravitational constant G

Many precision measurements of G have produced a spread of results incompatible with measurement errors. Clearly an unknown source of systematic errors is at work. It is proposed here that most of the discrepancies derive from subtle deviations from Hooke's law, caused by avalanches of entangled dislocations. The idea is supported by deviations from linearity reported by experimenters measuring G, similar to what observed, on a larger scale, in low-frequency spring oscillators. Some mitigating experimental apparatus modifications are suggested.
