QCD Sum Rules for Heavy Baryons at Next-to-Leading Order in alpha_s

S. Groote, J. G. Körner, O. I. Yakovlev

We derive QCD sum rules for heavy baryons at leading order in $1/ m_{Q}$ and at next-to-leading order in $α_{s}$ . The calculation involves the evaluation of four different perturbative…

Heavy Baryons and QCD Sum Rules

O. I. Yakovlev

We discuss an application of QCD sum rules to the heavy baryons $Λ_{Q}$ and $Σ_{Q}$ . The predictions for the masses of heavy baryons, residues and Isgur-Wise function are presented. Th…

Two-loop Anomalous Dimensions of Heavy Baryon Currents in Heavy Quark Effective Theory

S. Groote, J. G. Körner, O. I. Yakovlev

We present results on the two-loop anomalous dimensions of the heavy baryon HQET currents $J = (q^{T} C Γ τ q) Γ^{'} Q$ with arbitrary Dirac matrices $Γ$ and $Γ^{'}$ . From our general result we ob…
