Instanton Correction of Prepotential in Ruijsenaars Model Associated with N=2 SU(2) Seiberg-Witten Theory
Instanton correction of prepotential of one-dimensional SL(2) Ruijsenaars
model is presented with the help of Picard-Fuchs equation of Pakuliak-Perelomov
type. It is shown that the instanton induced prepotential reduces to that of
the SU(2) gauge theory coupled with a massive adjoint hypermultiplet.Comment: revtex, 15 pages, to be published in Journal of Mathematical Physic
Infinity Cancellation, Type I' Compactification and String S-Matrix Functional
Nonvanishing tadpoles and possible infinities associated in the multiparticle
amplitudes are discussed with regard to the disk and diagrams of the
Type I' compactification. We find that the infinity cancellation of
type theory extends to this case as well despite the presence of tadpoles
localized in the D-brane world-volume and the orientifold surfaces. Formalism
of string S-matrix generating functional is presented to find a consistent
string background as c-number source function: we find this only treats the
cancellation of the tadpoles in the linearized approximation. Our formalism
automatically provides representation of the string amplitudes on this
background to all orders in .Comment: 18 pages, Latex, more references adde

D-term Dynamical Supersymmetry Breaking Generating Split N=2 Gaugino Masses of Mixed Majorana-Dirac Type
Under a few mild assumptions, N=1 supersymmetry in four dimensions is shown
to be spontaneously broken in a self-consistent Hartree-Fock approximation of
BCS/NJL type to one-loop off-shell, in the gauge theory specified by the gauge
kinetic function and the superpotential of adjoint chiral superfields, in
particular, that possesses N=2 extended supersymmetry spontaneously broken to
N=1 at tree level. The N=2 gauginos receive mixed Majorana-Dirac masses and are
split. We derive an explicit form of the gap equation, showing the existence of
a nontrivial solution.Comment: 4 pages, the paper extended (a numerical plot of the solution to the
gap equation, an estimate of the decay rate of the metastable vacuum, and
discussion on nonvanishing term induced by the D term dynamical
supersymmetry breaking diven), references adde
