Quenched 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 کاملBaryon 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
Partially quenched theories are theories in which the valenceand seaquark masses are different. In this paper we calculate the nonanalytic one-loop corrections of some physical quantities: the chiral condensate, weak decay constants, Goldstone boson masses, BK and the K + → π+π0 decay amplitude, using partially quenched chiral perturbation theory. Our results for weak decay constants and masses...
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 کاملHeavy-Meson Observables at One-Loop in Partially Quenched Chiral Perturbation Theory
I present one-loop level calculations of the Isgur-Wise functions for B → D(∗)eν, of the matrix elements of isovector twist-2 operators in B and D mesons, and the matrix elements for the radiative decays D∗ → Dγ in partially quenched heavy quark chiral perturbation theory. Such expressions are required in order to extrapolate from the light quark masses used in lattice simulations of the forese...
