The question of who is and who is not a bilingual is more difficult to answer than it first appears. Bilingualism was long regarded as the equal mastery of two languages, a definition that still prevails in certain glossaries of linguistics. However, today's complex world requires a more exact definition and analysis of the competencies that community members require to interact with speakers o...

The next-to-leading order QCD corrections to the production of a W -boson in association with a jet containing a heavy quark are presented. The calculation is fully differential in the final state particle momenta and includes the mass of the heavy quark. We study for the case of the Tevatron the sensitivity of the cross section to the strange quark distribution function, the dependence of the ...

We study the inclusive production of Λ (Λ̄) in several high energy collision processes (e+e−, e±p, ν(ν̄)p, pp), in view of an accurate determination of the unpolarized and polarized fragmentation functions of a quark into a Λ (Λ̄). For polarized fragmentation functions the inaccuracy and the scarcity of present data do not allow to distinguish between various theoretical models. We will indicate h...

The top quark with its mass of about 172 GeV/c is the most massive fundamental particle observed by experiment. In this talk we highlight the most recent measurements of several top quark properties performed with the CDF detector based on data samples corresponding to integrated luminosities up to 1 fb. These results include a search for top quark pair production via new massive resonances, me...

In these lectures I want to discuss how the structure functions in deep inelastic scattering relate to quark and gluon correlation functions. In particular we will consider the issue of intrinsic transverse momenta of quarks, which becomes important in processes like 1-particle inclusive leptoproduction. Some examples of cross sections and asymmetries, in particular in polarized scattering proc...

We developed a question and answering system QUARK. This system extracts an answer from newspaper corpus as a knowledge source by a statistical technique. We participated in NTCIR3 QAC task to evaluate our system.
