baryon-baryon interactions in chiral effective field theory
We have constructed the leading order strangeness S = −1,−2 baryon-baryon potential in a chiral effective field theory approach. The chiral potential consists of one-pseudoscalar-meson exchanges and non-derivative four-baryon contact terms. The potential, derived using SU(3) f symmetry constraints, contains six independent low-energy coefficients. We have solved a regularized Lippmann-Schwinger...
متن کاملbaryon-baryon interactions using chiral effective field theory
We derive the leading order strangeness S = −2 baryon-baryon interactions in chiral effective field theory. The potential consists of contact terms without derivatives and of one-pseudoscalar-meson exchanges. The contact terms and the couplings of the pseudoscalar mesons to the baryons are related via SU(3)f symmetry to the S = −1 hyperonnucleon channels. We show that the chiral effective field...
متن کاملEffective Field Theory of Heavy Mesons
In this paper we present a detailed formulation for a recently proposed effective field theory to describe the nonperturbative QCD dynamics of heavy mesons. This effective theory incorporates with heavy quark symmetry (HQS) and the heavy quark effective theory (HQET). Heavy mesons in this theory are constructed as composite particles of a heavy quark bounded with the light degrees of freedom. T...
متن کاملExcited heavy baryon spectrum in large N c heavy quark effective theory
L = 1 excited heavy baryon masses are analyzed by heavy quark and large Nc expansions. In heavy quark limit, mass is parameterized by Λ̄ and it is expanded further by spin-flavor breaking operators to the zeroth order of 1/Nc. Expanding coefficients will be fixed by more data on the excited baryons in the near future. Typeset using REVTEX Email address: [email protected] Email address: liuc@c...
متن کاملTwo-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...
