"... We analyse open and mixed sector treelevel amplitudes consisting of two p − p ′ openstring and one or two p ′ − p ′ openstring vertex operators in the purely openstring sector, and two p − p ′ or p ′ − p ′ openstring and one closed string vertex operators, for N = 2 strings with a constant ma ..."

with momentum (ζ = ik). However, on taking the SeibergWitten (SW) low energy limit[2], there are considerable differences in the results one obtains and the interpretations of the results: the 4point function is local indicating the possible topological nature of the theory. The 3point function vanishes (on

If the fundamental quarks of QCD are replaced by massless adjoint quarks the pattern of the chiral symmetry breaking drastically changes compared to the standard one. It becomes SU(Nf) →SO(Nf). While for Nf = 2 the chiral Lagrangian describing the “pion ” dynamics is wellknown, this is not the case at Nf> 2. We outline a general strategy for deriving chiral Lagrangians for the coset spaces Mk = SU(k)/SO(k), and study in detail the case of Nf = k = 3. We obtain two and fourderivatives terms in the chiral Lagrangian on the coset space M3 = SU(3)/SO(3), as well as the Wess–Zumino– Novikov–Witten term, in terms of an explicit parameterization of the quotient manifold. Then we discuss stable topological solitons supported by this Lagrangian. Aspects of relevant topological considerations scattered in the literature are reviewed. The same analysis applies to SO(N) gauge theories with Nf Weyl flavors in the vector representation. 1

We discuss the possible applications of string theory for the construction of generalizations of the SU(3) × SU(2) × U(1) standard model of strong and electroweak interactions. This includes an investigation of effective d = 4 dimensional supergravity theories that could be derived from higher dimensional string theories (d = 10) and Mtheory (d = 11). It is shown how the question of unification of gauge and gravitational coupling constants could find a solution within this framework. The mechanism of hidden sector supersymmetry breakdown and its consequences for the pattern for soft supersymmetry breaking terms are discussed in detail. 1
