Phenomenological Method and Meditation
In recent psychological literature on meditation, the terms "phenomenology" and "phenomenological" are sometimes used rather loosely to refer to introspective reports given by experimental subjects about their experiences during meditation. I Some psychologists have even developed questionnaires and procedures, characterized as ways of operationalizing phenomenology, so that subjects' introspec...
متن کاملFinal State Interactions in Kaon Decays
We quantify the important effect of strong final state interactions in the weak K → 2π amplitudes, using the measured π-π phase shifts with J = 0 and I = 0, 2. The main results of this analysis, with their implications for ε/ε and the ∆I = 1/2 rule, have been already presented in a previous paper [1]. Here we provide a detailed formal derivation of those results and further discuss the Standard...
متن کاملFinal State Interactions in Kaon Decays Revisited
We examine effects of final state interactions (FSI) in kaon decays using a new scheme without the Omnés function, and show that while ∆I = 1/2 rule is impossible to be explained in terms of FSI alone, ′/ ∼ 16.5 × 10−4 is obtained through FSI, if the calculation is concerned only with the CP-violating parts. The ππ contribution to the mL −mS mass difference is shown to be about 14%, if the size...
متن کاملSearch for Tensor Interactions in Kaon Decays at DAΦNE
The semileptonic kaon decays Kl2γ and Kl3 are considered. We use the most general forms of the matrix elements for these decays. Additional terms could arise as a result of new tensor interactions between quarks and leptons. Such terms have been detected in a recent experiments. The high precision experiments at DAΦNE may be ideal to confirm these results. E-mail: [email protected] Permanen...
متن کاملA Phenomenological Lagrangian Approach to Two Kaon Photoproduction and Pentaquark Searches
We examine cross sections for the processes γN → NKK in the framework of a phenomenological Lagrangian. We include contributions from Λ and Σ resonances up to spin 3/2, as well as those from an exotic Θ. We allow the Θ to have spin 1/2 or 3/2, with either positive or negative parity in each case. We also allow the state to be either isovector or isoscalar. We find that the scenario that most cl...
