Baryon Chiral Perturbation Theory to One Loop
Pion Double Charge exchange (DCX) scattering off a nuclear target at threshold, is calculated within the framework of Heavy Baryon Chiral Perturbation Theory (HBChPT) to one loop. An estimate for the (2-nucleon) 1-loop correction is obtained in the static limit and using an impulse approximation. We find a small (1.6%) increase relative to the leading order tree graphs. PACS numbers: 12.39.Fe, ...
متن کاملQuenched Chiral Perturbation Theory to one loop
We calculate the divergences of the generating functional of quenched Chiral Perturbation Theory at one loop, and renormalize the theory by an appropriate definition of the counterterms. We show that the quenched chiral logarithms can be accounted for by defining a renormalized B0 parameter which, at lowest order, is proportional to the vacuum expectation value of the scalar quark density. Fina...
متن کاملChiral Perturbation Theory Beyond One Loop
The existing Chiral Perturbation Theory (ChPT) calculations at order p6 are reviewed. The principles of ChPT and how they are used are introduced. The main part is a review of the twoand three-flavour full two-loop calculations and their comparison with experiment. We restrict the discussion to the mesonic purely strong and semileptonic sector. The review concludes by mentioning the existing re...
متن کاملTopological susceptibility in staggered fermion chiral perturbation theory
Abstract The topological susceptibility of the vacuum in quantum chromodynamics has been simulated numerically using the Asqtad improved staggered fermion formalism. At nonzero lattice spacing the residual fermion doublers (fermion “tastes”) in the staggered fermion formalism give contributions to the susceptibility that deviate from conventional continuum chiral perturbation theory. In this br...
متن کاملTwo–loop integrals in chiral perturbation theory
We consider chiral perturbation theory in the meson sector at order E 6. In the terminology of the external field technique, the two–loop graphs so generated are of the sunset type. We discuss the evaluation of several of these in the case where the masses of the particles running in the loops are equal. In particular, we present integral representations that are suitable for the evaluation of ...
