A novel method to study symmetry violation in the decay of neutral kaons is presented. The method makes use of initially pure K sup 0 and K sup -0 beams, produced in p anti p annihilations at LEAR. The detector and the tagging are described, and the evisaged physics is discussed. (ERA citation 11:028740)

Lectures are given on weak decays from a phenomenological point of view, emphasizing new results and ideas and the relation of recent results to the new standard theoretical model. The general framework within which the weak decay is viewed and relevant fundamental questions, weak decays of noncharmed hadrons, decays of muons and the tau, and the decays of charmed particles are covered. Limitation is made to the discussion of those topics that either have received recent experimental attention or are relevant to the new physics. (JFP) 178 references. (ERA citation 04:017391)

The beta decay of free quarks is studied in the framework of the standard SU(2) x U(1) model of weak and electromagnetic interactions. The so-called 'weak' part of radiative corrections is evaluated to order alpha in one-loop approximation using a renormalization scheme, which adjusts the counter terms to the electric charge, and to the mass of the charged and neutral vector bosons, Msub(w) and Msub(o), respectively. The obtained result is, to a good approximation, equal with the 'weak' part of radiative corrections for the semileptonic decay of any hyperon. It is shown in the model that the methods, which work excellently in case of the 'weak' corrections, do not, in general, provide us with the dominant part of the 'photonic' corrections.

We analyze the consequences of the usual assumption of a constant function to fit non-resonant decays from experimental Dalitz plot describing charmed meson decays. We first show, using the D(sup +) -> K(sup 0) (pi)(sup +) (pi) (sup 0) decay channel as an example, how an inadequate extraction of the non- resonant contribution could yield incorrect measurements for the resonant channels. We analyze how the correct study of this decay will provide a test for the validity of factorization in D meson decays. Finally, we show how form factors that can be measured from the D(sup +)(sub s) -> (pi)(sup -) (pi)(sup +) (pi)(sup +) decay. We emphasize its relevance for the study of the decay (tau) -> v(sub t) 3(pi) and the extraction of the (alpha)(sub 1) meson width. (author) 26 refs., 6 figs.
