We present the full O(α s) longitudinal spin-spin correlations for heavy-quark pair production at e + e − high-energy colliders in closed analytical form. In such reactions , quark and antiquark have strongly correlated spins , and the longitudinal components are dominant.

The analytic expressions for the production cross sections of polarized bottom and top quarks in e + e − annihilation are explicitly derived at the one-loop order of strong interactions. Chirality-violating mass effects will reduce the longitudinal spin polarization for the light quark pairs by an amount of 3% , when one properly considers the massless… (More)

The Local Query Processors Manager (LOP Manager) provides backup support for information retrieval in the Composite Information System / Tool Kit (CIS/TK). The LQP Manager reroutes queries to alternate databases when the currently selected database becomes inaccessible. The mechanism used to achieve this rerouting groups together all the databases in the… (More)

We calculate one-loop radiative QCD corrections to the three polarized and unpolar-ized structure functions that determine the beam-quark polar angle dependence of the alignment (or longitudinal) polarization of light and heavy quarks produced in e + e −-annihilations. We present analytical and numerical results for the alignment polarization and its polar… (More)

In modern surgery, a multitude of minimally intrusive operational techniques are used which are based on the punctual heating of target zones of human tissue via laser or radio-frequency currents. Traditionally, these processes are modeled by the bioheat equation introduced by Pennes, who considers Fourier's theory of heat conduction. We present an… (More)

We present a new derivation of the O (α) differential cross section for the production of massive quarks in e + e − collisions. In our calculation we express the three-particle phase-space integration of the bremsstrahlung process in terms of a general set of analytic integral solutions. A consistent treatment of the QCD one-loop corrections to the… (More)

This paper presents the non-linear generalization of a previous work on matrix differential models [1]. It focusses on the construction of approximate solutions of first-order matrix differential equations Y ′ (x) = f (x,Y (x)) using matrix-cubic splines. An estimation of the approximation error, an algorithm for its implementation and illustrative examples… (More)
