Choi et al. Belle Collaboration<br/>A distinct peak is observed in the π^{±} ψ^{′} invariant mass distribution near 4.43 GeV in B→Kπ^{±} ψ^{′} decays. A fit using a Breit-Wigner resonance shape yields a peak mass and width of M=4433±4(stat)±2(syst)  MeV and Γ=45_{-13}^{+18} (stat)_{-13}^{+30} (syst)  MeV. The p...<br/>[Phys. Rev.

Hypercharge mediation thus naturally teams up with anomaly mediation. The mixed scenario predicts a distinctive yet viable su...<br/>[Phys. Rev.
