ZTF - 94 / 05 Quark off - shell contributions to K L → γγ in a bound - state approach
We present a new piece of evidence in favour of the importance of the quark off-shellness in the kaon. The matrix elements of the flavour-changing operators for KL → γγ comply with the general behaviour of the matrix elements expected in the pairing boundstate model used here. The present calculation in essence agrees with previous chiral-quark results. The off-shell contribution turns out to b...
متن کاملOff-shell and non-static contributions to heavy-quarkonium production
We have shown that if one relaxes the constraint that the quarks in a heavy quarkonium are at rest and on-shell, new contributions to the discontinuity of the production amplitude appear. These can be seen as a s-cut in the amplitude and are on the same footage as the classical cut of the Colour-Singlet Model (CSM), where the heavy quarks forming the quarkonium are put on-shell by hypothesis. W...
متن کاملBound-valence-quark contributions to hadron structure functions.
The conventional separation of " valence " and " sea " quark distributions of a hadron implicitly assumes that the quark and anti-quark contributions to the sea are identical in shape, although this cannot be strictly correct due to the exclusion principle. A new sepnration of " bound va.lence " and " non-valence " quark distributions of a hadron is proposed which incorporates the Pauli princip...
متن کاملa frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
15 صفحه اولfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
