Heavy flavor production with gluon bremsstrahlung

The amplitude squared is presented for the scattering of two massive fermions and three massless gauge bosons in a concise analytic form. The expression is directly applicable to such reactions as: e + e −→ γγγ, gg→Q Qg , and gg→ g, with massive electrons, quarks, and gluinos, respectively. Phenomenological applications to heavy flavor production are discussed.

Errata: Symmetric Flow Characteristics of Thin Rectangular Wings

I the text immediately after Eq. (6) in the above paper there is a sentence with the unfortunate and incorrect statement, set of Eqs. (1-6) summarizes in a concise analytic form the knowledge that at present is obtained from linearized theory as to .... The correct formulation is, ... in a concise analytic form most of the information that at present .... It is so because at least one pioneering analytic result ought io be mentioned in the present situation. Lagerstrom and Graham 1 obtained by means of conical flow theory the following analytical result on slender rectangular wings f or M>1,

Quasi-exact solution of the optical Jahn-Teller problem

The presented method is based on an extension of the Goldberger-Adams theorem and on a systematic application of Wick's theorem. The latter leads to combinatorial problems, which in general are complicated but well-fit to be handled by computers. In the two pureJT-casesE-e andT-t the combinatorial problems are simple. In particular in theE-e-case (trigonal) the optical response can be written in a concise analytical form. It is shown further that by means of a one-to-one correspondence of the respective combinatorial problems it suffices to calculate the complete sequence of moments in the strong coupling limit to write down expressions for the optical response with arbitrary coupling, which are exact both in the strong and weak coupling limit.
