Fine and Hyperfine Splittings of Charmonium and Bottomonium: An Improved Perturbative QCD Approach
S. Recksiegel, Y. Sumino
We extend the formalism based on perturbative QCD that was developed in our previous work, and compute the hyperfine splittings of the bottomonium spectrum as well as the fine and…
Comparing the QCD potential in Perturbative QCD and Lattice QCD at large distances
S. Recksiegel, Y. Sumino
We compare the perturbatively calculated QCD potential to that obtained from lattice calculations in the theory without light quark flavours. We examine E_tot(r) = 2 m_pole + V_QCD…
Large enhancement of D -> e nu and Ds -> e nu in R Parity violating SUSY models
A. G. Akeroyd, S. Recksiegel
The purely leptonic decays D -> e nu and Ds -> e nu, for which no experimental limits exist, are highly suppressed in the Standard Model. Mere observation of these decays at the B…
Improved Perturbative QCD Approach to the Bottomonium Spectrum
S. Recksiegel, Y. Sumino
Recently it has been shown that the gross structure of the bottomonium spectrum is reproduced reasonably well within the non-relativistic boundstate theory based on perturbative QC…
Perturbative QCD Potential, Renormalon Cancellation and Phenomenological Potentials
S. Recksiegel, Y. Sumino
We examine the total energy E_tot(r) = 2 m_pole + V_QCD(r) of the b\bar b system within perturbative QCD up to O(α_S^3). We extend a previous analysis by incorporating effects of t…
