Two-loop Anomalous Dimensions of Heavy Baryon Currents in Heavy Quark Symmetry
نویسنده
چکیده
This talk presents details of the calculation of two-loop corrections to heavy baryon currents containing one heavy quark in leading order of the 1/mQ-expansion, i.e. in the limit of Heavy Quark Symmetry (HQS). The calculations lead to the determination of the anomalous dimension of these currents. I also discuss problems with different γ5-schemes and their solution by the finite renormalization procedure. Talk given at the Triangle Graduate School in Particle Physics, Prague, Czech Republic, September 2–10, 1996

Two-loop anomalous dimensions of heavy baryon currents in heavy quark effective theory.
We present results on the two-loop anomalous dimensions of the heavy baryon HQET currents J = (qTCΓτq)Γ′Q with arbitrary Dirac matrices Γ and Γ. From our general result we obtain the two-loop anomalous dimensions for currents with quantum numbers of the ground state heavy baryons ΛQ, ΣQ and Σ∗Q. As a by-product of our calculation and as an additional check we rederive the known two-loop anomalo...

Two-loop anomalous dimensions for currents of baryons with two heavy quarks in NRQCD. Abstract We present analytical results on the two-loop anomalous dimensions of currents for baryons, containing two heavy quarks J = [Q iT CΓτ Q j ]Γ ′ q k ε ijk with arbitrary Dirac matrices Γ and Γ ′ in the framework of NRQCD in the leading order over both the relative velocity of heavy quarks and the invers...
متن کاملShort-distance expansion of heavy-light currents at order 1/mQ.
The short-distance expansion of the heavy-light currents q̄ γQ and q̄ γγ5Q is constructed to order 1/mQ, and to next-to-leading order in renormalization-group improved perturbation theory. It is shown that the 10 × 10 anomalous dimension matrix, which describes the scale dependence of the dimension-four effective current operators in the heavy quark effective theory, is to a large extent determin...
متن کاملTwo-loop soft anomalous dimensions and next-to-next-to-leading-logarithm resummation for heavy quark production.
I present results for two-loop soft anomalous dimensions for heavy quark production which control soft-gluon resummation at next-to-next-to-leading-logarithm accuracy. I derive an explicit expression for the exact result and study it numerically for top quark production via e(+)e(-)-->tt, and I construct a surprisingly simple but very accurate approximation. I show that the two-loop soft anomal...
متن کاملChiral Lagrangians for radiative decays of heavy hadrons.
The radiative decays of heavy mesons and heavy baryons are studied in a formalism which incorporates both the heavy quark symmetry and the chiral symmetry. The chiral Lagrangians for the electromagnetic interactions of heavy hadrons consist of two pieces: one from gauging electromagnetically the strong-interaction chiral Lagrangian, and the other from the anomalous magnetic moment interactions ...
