Particle χ_(c0)(3915) was first observed by the Belle experiment in the ωJ/ψ invariant mass spectrum in the process B→KωJ/ψ and subsequently confirmed by the BaBar experiment.Both experiments reported the resona...

Within the framework of perturbative QCD factorization,we investigate the nonfactorizable contributions to the factorization-forbidden quasi-two-body decays B_((s))→h_((χ)_(c0))→hπ^(+)π^(-)(K^(+)K^(-))with h=π,K...

We perform a lattice QCD calculation of theχ_(c0)→2γdecay width using a model-independent method that does not require the momentum extrapolation of corresponding off-shell form factors.The simulation is performed ...
