摘要

We discuss the possible production and discovery channels in e(+)e(-) and pp machines of the X-b, the bottomonium counterpart of X(3872) and the putative isoscalar analogue of the charged bottomoniumlike states Z(b) discovered by Belle. We suggest that the X-b may be close in mass to the bottomonium state chi(b1)(3P), mixing with it and sharing its decay channels, just as X(3872) is likely a mixture of a (D) over barD* molecule and chi(c1)(2P). Consequently, the experiments which reported observing chi(b1)(3P) might have actually discovered the Xb, or a mixture of the two states.

D(D)over-bar* scattering and χc1 (3872) in nuclear matter

M. Albaladejo, J. Nieves, L. Tolos

Summary: Researchers studied the behavior of X(3872) in dense nuclear matter, revealing significant nuclear corrections on the scattering matrix and resonance pole position, and discussing the dependence of these results on the molecular component in the wave function.

From the line shape of the X(3872) to its structure

Angelo Esposito, Luciano Maiani, Alessandro Pilloni, Antonio D. Polosa, Veronica Riquer

Summary: The LHCb collaboration found a significant negative effective range in the X(3872) line shape study, suggesting a compact hidden charm structure interacting with unbound D(D) over bar* pairs. This conclusion is supported by a general pattern observed in exotic mesons.

Radiative decays of the spin-2 partner of X(3872)

Pan-Pan Shi, Jorgivan M. Dias, Feng-Kun Guo

Summary: It is expected that X(3872) has a spin-2 partner, X2, with a mass below the D*D over bar * threshold. The structure with a mass of (4014.3 & PLUSMN;4.0 & PLUSMN; 1.5) MeV reported by Belle Collaboration is considered a good candidate for X2. The radiative decay widths and signal of X2 in two-photon collisions are estimated, and the search for X2 signal in the γJ/ψ invariant mass distribution is suggested.

X(3872) ? J=??? and X(3872) ? J=???? decays

Qi Wu, Jun-Zhang Wang, Shi-Lin Zhu

Summary: We investigate the contribution of rho and omega mesons to the radiative decays X(3872) -> J/psi pi gamma and X(3872) -> J/psi pi pi gamma. The dominance of the omega meson is observed in the X(3872) -> J/psi pi gamma decay. However, in the X(3872) -> J/psi pi pi gamma decay, the cascade decays through the rho and omega mesons are strongly suppressed compared to the diagrams involving psi(2S) or three-body decay of rho. The branching ratios of X(3872) -> J/psi pi gamma and X(3872) -> J/psi pi pi gamma are (8.10+3.50 -2.88 ) x 10-3 and (2.38 +/- 1.06)%, respectively, and could be measured by the BESIII and LHCb collaborations. Importantly, the decays X(3872) -> J/psi pi gamma and X(3872) -> J/psi pi+pi-gamma can be used to extract the couplings gX psi omega and gX psi rho, which probe the isoscalar and isovector components of the X(3872) wave function, respectively.

Production of Xb via ?(5S, 6S) radiative decays

Xiao-Yun Wang, Zu-Xin Cai, Gang Li, Shi-Dong Liu, Chun-Sheng An, Ju-Jun Xie

Summary: We investigated the process upsilon(5S , 6S) -> X-gamma(b), assuming Xb to be a molecular state of B B & macr;*. Two types of meson loops, B(*)B & macr;(*) and B1B & macr;(*), were considered. To explore the rescattering mechanism, we calculated the relevant branching ratios using an effective Lagrangian based on heavy quark symmetry. The branching ratios for upsilon(5S , 6S) -> X-gamma(b) were found to be in the orders of 10(-7) to 10(-6). These significant branching ratios might be observed at BelleII, providing important insights into the inner structures of the exotic state Xb.

Semileptonic Bc decays to P-wave charmonium and the nature of χc1(3872)

P. Colangelo, F. De Fazio, F. Loparco, N. Losacco, M. Novoa-Brunet

Summary: The hadronic form factors of Bc semileptonic decays can be expressed using universal functions near the zero-recoil point, and a next-to-leading order calculation has been performed to classify the universal functions. Relations among the form factors of the same and different modes have been derived, reducing the hadronic uncertainty in these channels. This approach also helps in studying the debated nature of chi c1(3872) by comparing its production in Bc semileptonic decays with other 2P charmonium modes.

Establishing the heavy quark spin and light flavor molecular multiplets of the X(3872), Zc(3900), and X(3960) br

Teng Ji, Xiang-Kun Dong, Miguel Albaladejo, Meng-Lin Du, Feng-Kun Guo, Juan Nieves

Summary: The LHCb Collaboration recently reported a near-threshold enhancement X(3960) and showed that it can be described by either a bound or a virtual state. Using this discovery and existing information, a complete spectrum of S-wave hadronic molecules formed by a pair of charm and anticharm mesons is established, resulting in predicted pole positions for the newly observed state.

Galilean-invariant effective field theory for the X(3872) at next-to-leading order

Eric Braaten, Li-Ping He, Jun Jiang

Summary: XEFT is a low-energy effective field theory for charm mesons and pions that systematically improves the description of the X(3872) resonance. A new formulation and renormalization scheme have been introduced to simplify calculations in XEFT, which involve a new dynamical field for a pair of charm mesons and a subtraction of amplitudes at the complex D*(0)-(D) over bar (0) threshold. These are illustrated by calculating the complex pole energy of X and the D*(0)-(D) over bar (0) scattering amplitude to next-to-leading order using Galilean-invariant XEFT.

Summary: The production of chi(c1)(3872) and psi(2S) hadrons in proton-proton collisions at a center-of-mass energy of 8 TeV was studied, showing that the prompt production fraction decreases with increasing charged particle multiplicity. The ratio of chi(c1)(3872) to psi(2S) cross sections also decreases with multiplicity for promptly produced particles, while no significant dependence on multiplicity was observed for particles produced away from the collision vertex in b-hadron decays.

Summary: In this study, we investigated the processes e(+)e(-)+ omega chi(bJ)(1P) (J = 0, 1, or 2) using samples at p = 10.701, 10.745, and 10.805 GeV, with corresponding integrated luminosity of 1.6, 9.8, and 4.7 fb(-1). We observed the first signals of omega chi(bJ)(1P) at p = 10.745 GeV. Our data suggest that the internal structures of the gamma(10753) and gamma(10860) states may differ. Furthermore, we searched for the bottomonium equivalent of the X(3872) state decay into omega gamma(1S), but no significant signal was found for masses between 10.45 and 10.65 GeV/c(2).

Molecular Nature of X(3872) in B0 → K0X(3872) and B+→ K+X(3872) Decays

Hao-Nan Wang, Li-Sheng Geng, Qian Wang, Ju-Jun Xie

Summary: We study the decays of B-0 -> (KX)-X-0 (3872) and B+ -> K+X(3872) using the X(3872) resonance coupled to the D (D) over bar* + c.c channel. Besides the short-distance interaction mechanism, we also consider the long-distance rescattering diagrams of D (D) over bar*. The difference in mass thresholds and the narrow width of X(3872) at the X(3872) mass lead to significant differences in the loop functions of D (D) over bar*(0) and D+ (D) over bar*-. Taking this into account, we naturally obtain a ratio of B[B-0 -> K-0 X(3872)]/B[B+ -> K+X (3872)] similar to 0.5. Based on this result, we evaluate the decay widths of B-s(0) -> eta(eta')X(3872). Future experimental measurements of these decays are expected to provide insight into the nature of the X(3872) resonance.

Insights into the nature of X(3872) through B meson decays

Zhi-Qing Zhang, Zhi-Lin Guan, Yan-Chao Zhao, Zi-Yu Zhang, Zhi-Jie Sun, Na Wang, Xiao-Dong Ren

Summary: In this study, we investigate the B-c,B-u,B-d -> X(3872)P decays using the perturbative QCD approach. We obtain several results, including the branching ratios of different decays and CP violations. The branching ratios of B-c(+)-> X(3872)pi(+) and B-c(+)-> X(3872)K+ decays are consistent with previous studies but larger than those predicted by other approaches. The branching ratio of the B+-> X(3872)K+ decay is smaller than previous calculations but still slightly larger than experimental limits. The B-u,B-d -> X(3872)pi decays have significantly smaller branching ratios compared to B-u,B-d -> X(3872)K decays. The CP violations in these decays are small and the mixing-induced CP violation of the B -> X(3872)K-S(0) decay is consistent with the current world average value of sin2 beta=(69.9 +/- 1.7)%. Experimental measurements of the branching ratios and CP violations can help probe the nature of X(3872) and test the theoretical predictions.
