Z 2 orientifold with spontaneously broken supersymmetry
We present a Z2 × Z2 four dimensional orientifold in which supersymmetry is broken by a temperature-like Scherk-Schwarz mechanism. As usual in this type of models, at the tree-level the breaking affects only the branes tangent to the direction involved by the SS deformation, and it can propagate only through radiative corrections to other sectors, where the gauge group is broken. The result is ...
متن کاملThe Integrable Open Xxz Chain with Broken Z2 Symmetry
The hamiltonian of an asymmetric diffusion process with injection and ejection of particles at the ends of a chain of finite length is known to be relevant to that of the spin1 2 XXZ chain with integrable boundary terms. However, the inclusion of boundary sources and sinks of particles breaks the arrow-reversal symmetry necessary for solution via the usual Bethe Ansatz approach. Developments in...
متن کاملGeneralized string compactifications with spontaneously broken supersymmetry
The Narain lattice construction of string compactifications is generalized to include spontaneously broken supersymmetry. Consistency conditions from modular invariance and Lorentz symmetry are solved in full generality. This framework incorporates models where supersymmetry breaking is inversely proportional to the radii of compact dimensions. The enhanced lattice description, however, might a...
متن کاملLow Energy Processes Associated with Spontaneously Broken N = 2 Supersymmetry
We consider low energy processes described by the N = 2 supercurrent on its partially (to N = 1) and spontaneously broken vacuum and the attendant Nambu-Goldstone fermion (NGF), which the presence of the electric and magnetic Fayet-Iliopoulos (FI) terms is responsible for. We show suppressions of amplitudes decaying into the NGF as its momentum becomes small. In the lagrangian realization (name...
متن کاملTransversality for Z2-orbifolds
Equivariant transversality phenomena are studied for PL locally linear actions of the group with two elements. In this setting with stability assumptions, the obstruction to making a given map f : M ! N transverse to the xed set N Z 2 is given by an element of Sect(BL(M ; N) # M Z 2), i.e. a generalized cohomology class with twisted coeecients. Here BL(M ; N) is a spectrum whose homotopy groups...
