“…The corresponding transition matrix elements have been computed by using quark models [3][4][5][6]. 1 Indeed the resulting value m η b = 9390.9±2.1 MeV extracted from the BaBar experiment [1,2] was consistent with the value obtained from the similar measurements made at CLEO [8,9], leading to the following value of the hyperfine splitting [10],…”

We present the results of our lattice QCD study of the hadronic matrix elements relevant to the physical radiative J/ψ → η c γ and h c → η c γ decays. We used the twisted mass QCD action with N f = 2 light dynamical quarks and from the computations made at four lattice spacings we were able to take the continuum limit. Besides the form factors parameterizing the above decays we also computed: (i) the hyperfine splitting and obtained ∆ = 112 ± 4 MeV, (ii) the annihilation constant f J/ψ which agrees with the one inferred from the measured Γ(J/ψ → e + e − ).

Great strides have been made in the understanding of bound states of the bottom quark, b, and its antiquark,b-bar , since the discovery of the first Ψ resonances in 1977. These bound states, known as bottomonium, have a rich spectrum whose masses and transition amplitudes shed valuable light on the strong interactions. We review some recent developments in bottomonium physics, including the discovery of the spin-singlet states eta_b(1S,2S) and h_b(1P,2P), the first D-wave states, one or more candidates for spin-triplet chi_b(3P) excitations, and above-threshold states with strong transitions to states below threshold. We also present information about transitions, production, and signatures of new physics
