We examine the photoproduction of the light scalar mesons f0-a0(980) with emphasis on isospinviolating f0 and a0 mixing due to the mass difference between neutral and charged kaons. General forms for the invariant amplitude for scalar meson photoproduction are derived, which yield expressions for the invariant mass distribution of the final meson pairs. A final state interaction form factor is obtained which incorporates f0 and a0 mesons, KK threshold effects, and f0 − a0 mixing. This form factor is applied to predict the effective mass distribution of the ππ and KK pairs in the vicinity of the KK threshold. An estimate of the role of isospin mixing near threshold is provided. The potential role of polarized photons and protons is also discussed.

“…(2), obtained in the tree level of approximation, one must describe the neutron decay process with accuracy that is better than the expected experimental accuracy. Assuming that the accuracy in future neutron decay experiments can reach a level of about 10 −3 -10 −4 , we wish to describe the neutron decay with theoretical accuracy by about 10 −5 and our description must include all recoil and radiative corrections [13][14][15][16][17][18][19][20][21]. To do this we will use recent results of calculations [9] of radiative corrections for neutron decay in the effective field theory (EFT) with some necessary modifications.…”

A general analysis of the sensitivities of neutron β-decay experiments to manifestations of possible interaction beyond the standard model is carried out. In a consistent fashion, we take into account all known radiative and recoil corrections arising in the standard model. This provides a description of angular correlations in neutron decay in terms of one parameter, which is accurate to the level of ∼10 −5 . Based on this general expression, we present an analysis of the sensitivities to new physics for selected neutron decay experiments. We emphasize that the usual parametrization of experiments in terms of the tree-level coefficients a, A, and B is inadequate when the experimental sensitivities are at the same or higher level relative to the size of the corrections to the tree-level description.

“…Let us to quote the works [15,16]: "The requirement of antisymmetry of the final wave function M (k ′ , k)· χ S ·χ T (χ S and χ T are the spin and isotopic functions of the initial state) relative to the total permutation, including the permutation of the vector (k ′ → −k ′ ), permutation of the spin and isotopic variables does not change the signs of the amplitudes B 1 (θ), C 1 (θ), H 1 (θ), G 0 (θ) and N 0 (θ) after the turn θ → (π − θ), but the amplitudes B 0 (θ), C 0 (θ), H 0 (θ), G 1 (θ) and N 1 (θ) become inverse". It is accepted as the symmetry properties of these amplitudes ( Table 1)…”
