meson and the light - heavy quarkonium spectrum
We compute the c ¯ b spectrum from a first principle Salpeter equation obtained in a preceding paper. For comparison we report also the heavy-light quarko-nium spectrum and the hyperfine separations previously presented only in a graphical form. Notice that all results are parameter free. The spectrum and properties of the c ¯ b systems have been calculated various times in the past in the fram...
متن کاملHeavy Quarkonium Spectrum at O ( α 5 s m q ) and Bottom / Top Quark Mass Determination
We present the next-to-next-to-next-to-leading O(αsmq) result for the ground state energy of a heavy quarkonium system. On the basis of this result we determine the bottom quark mass from Υ(1S) resonance and provide an explicit formula relating the top quark mass to the resonance energy in tt̄ threshold production. PACS numbers: 12.38.Bx, 14.65.Fy, 14.65.Ha
متن کاملHeavy Quarkonium ∗
I review heavy quarkonium physics in view of recent experimental results. In particular, I discuss new results on spin singlet states, photon and hadronic transitions, D−states and discovery of yet unexplained narrow X(3872) state. 1 Quarkonia Quarkonium is a bound state of a quark and its anti-quark. Some properties of light and heavy quarkonia are compared to properties of positronium in Tabl...
متن کاملThe heavy quarkonium spectrum from quenched lattice QCD
We present results of simulations of the quenched quarkonium spectrum at two values of the lattice spacing and for quark masses around mc using the tadpole improved clover action. Attention is focussed on the lowest lying S and P states, and the triplet fine structure is obtained for the first time using a relativistic action. Typeset using REVTEX ∗Present Address: Department of Physics and Ast...
متن کاملB C Meson and the Light-heavy Quarkonium Spectrum
We compute the c ¯ b spectrum from a first principle Salpeter equation obtained in a preceding paper. For comparison we report also the heavy-light quarko-nium spectrum and the hyperfine separations previously presented only in a graphical form. Notice that all results are parameter free. The experimental observation of the B + c meson [1] has arisen new theoretical interest for the properties ...
