D ec 1 99 7 1 NNK and ΛΛ K Amplitudes in Chiral Perturbation Theory

چکیده
We explore the S-wave and P-wave amplitudes for NNK and ΛΛK interactions using chiral perturbation theory to O(m s log m s). In contrast to the large corrections found in P-wave amplitudes in the nonleptonic decay of octet baryons, the NNK amplitudes receive only small corrections to their tree-level values. The uncertainty in the ΛΛK amplitudes is found to be large.

Kaon-nucleon couplings for weak decays of hypernuclei.
We investigate the weak kaon-nucleon (NNK) S-wave and P-wave interactions using heavy baryon chiral perturbation theory. The leading 1-loop SU(3) breaking contributions to the ppK, pnK, and nnK couplings are computed. We nd that they suppress all NNK amplitudes by 30% to 50%. The ratio of neutron-induced to proton-induced hypernuclear decay widths is sensitive to such reductions. It has been ar...

An analysis of electromagnetic corrections to the (dominant) octet K → ππ hamiltonian using chiral perturbation theory is carried out. Relative shifts in amplitudes at the several per cent level are found.

We study the |∆I| = 3/2 and |∆S| = 2 amplitudes for hyperon decays of the form B → B ′ π at lowest order in chiral perturbation theory. At this order, the ∆I = 3/2 amplitudes depend on only one constant. We extract the value of this constant from experiment and find a reasonable description of these processes within experimental errors. The same constant determines the ∆S = 2 transitions which,...

The status of lattice calculations in Quantum Field Theory is reviewed. A major part is devoted to recent progress in formulating exact chiral symmetry on the lattice. Another topic which has received a lot of attention is the influence of dynamical quark effects. Attempts to quantify these effects for the light hadron spectrum and flavour singlet amplitudes are discussed, as well as other expe...
