O(α^nα_s^m) Corrections in e^+e^- Annihilation and τDecay
Levan R. Surguladze
The results of evaluation of mixed QED X QCD corrections to R(s) in e^+e^- annihilation and R_τ in hadronic decay of the τlepton to O(α^nα_s^m), m+n \leq 3, are presented. The net…
Virtual Supersymmetric Corrections in e^+e^- Annihilation
L. Clavelli, P. W. Coulter, Levan R. Surguladze
Depending on their masses, Supersymmetric particles can affect various measurements in Z decay. Among these are the total width (or consequent extracted value of ), enhancemen…
Gluino Contribution to the 3-loop QCD beta function in the Minimal Supersymmetric Standard Model
L. Clavelli, P. W. Coulter, L. R. Surguladze
We deduce the gluino contribution to the three-loop QCD βfunction within the minimal supersymmetric Standard Model (MSSM) from its standard QCD expression. The result is a first st…
Light Gluino Contribution in Hadronic Decays of Z boson and tau lepton to O(alpha_s^3)
Louis J. Clavelli, Levan R. Surguladze
The results of calculation of light gluino contributions to Gamma(Z--->hadrons) and Gamma(tau--->hadrons) to O(alpha_s^3) are presented. The net effect in the case of Z decay is no…
On the QCD perturbative expansion for e^+ e^- --> hadrons
Levan Surguladze, Davison E. Soper
We study the perturbative QCD series for the hadronic width of the Z boson. We sum a class of large ``pi^2 terms'' and reorganize the series so as to minimize ``renormalon'' effect…
Perturbative QCD Calculations of Total Cross Sections and Decay Widths in Hard Inclusive Processes
Levan R. Surguladze, Mark A. Samuel
A summary of the current understanding of methods of analytical higher order perturbative computations of total cross sections and decay widths in Quantum Chromodynamics is present…
STATUS OF PERTURBATIVE QCD EVALUATION OF HADRONIC DECAY RATES OF THE Z AND HIGGS BOSONS
Davison E. Soper, Levan R. Surguladze
We review the current status of the high order perturbative QCD evaluation of the hadronic decay rates of the Z and Higgs bosons. A systematic classification of the various types o…
Minimal Supersymmetric Higgs Boson Decay Rate in O(α_s^2) Perturbative QCD
Levan R. Surguladze
A short presentation of the results of the analytical evaluation of the O(α_s^2) QCD contributions in the fermionic decay rates of the neutral CP-odd minimal supersymmetric Higgs p…
Quark Mass Effects in Fermionic Decays of the Higgs Boson in Perturbative QCD
Levan R. Surguladze
The results of analytical evaluation of QCD contributions due to the nonvanishing quark masses to are presented. The ``triangle anom…
