    Semileptonic decays $$B_{c}$$ B c meson to S-wave charmonia and X(3872) within the covariant light-front approach by Zhi-Jie Sun, Si-Yang Wang, Zhi-Qing Zhang, You-Ya Yang, Zi-Yu Zhang

    Published 2023-10-01
    “…In view of the $$R_{J/\Psi }$$ R J / Ψ anomaly released by the LHCb collaboration, it is necessary to systematically calculate the ratios $$R_X$$ R X with $$X=\psi (1S,2S,3S),\eta _c(1S,2S,3S),X(3872)$$ X = ψ ( 1 S , 2 S , 3 S ) , η c ( 1 S , 2 S , 3 S ) , X ( 3872 ) , which are helpful for checking the lepton flavor universality (LFU). We also take into account another two physical observables, the longitudinal polarization fraction $$f_{L}$$ f L and the forward–backward asymmetry $$A_{FB}$$ A FB , which can provide new clues for understanding the $$R_{J /\Psi }$$ R J / Ψ anomaly. …”
