Twisted Moduli and Supersymmetry Breaking
We consider twisted moduli contributions to supersymmetry breaking in effective type I string constructions involving intersecting D5i and D9-branes using Goldstino angles to parametrise the supersymmetry breaking. It is well known that twisted moduli enter at tree-level into the gauge kinetic functions, and can provide new sources of gaugino mass if they develop F-term vacuum expectation value...
متن کاملDrinfeld-Twisted Supersymmetry and Non-Anticommutative Superspace
We extend the analysis of hep-th/0408069 on a Lorentz invariant interpretation of noncommutative spacetime to field theories on non-anticommutative superspace with half the supersymmetries broken. By defining a Drinfeld-twisted Hopf superalgebra, it is shown that one can restore twisted supersymmetry and therefore obtain a twisted version of the chiral rings along with certain Ward-Takahashi id...
متن کاملFrom Twisted Supersymmetry to Orbifold Lattices
We show how to derive the supersymmetric orbifold lattices of Cohen et al. [1, 2] and Kaplan et al. [3] by direct discretization of an appropriate twisted supersymmetric Yang-Mills theory. We examine in detail the four supercharge two dimensional theory and the theory with sixteen supercharges in four dimensions. The continuum limit of the latter theory is the well known Marcus twist of N = 4 Y...
متن کاملModular Symmetry, Twisted Sectors and Flavour
Twisted sectors of heterotic orbifolds have long been of phenomenological interest, since their massless states are automatically localized at the fixed points, resulting in effective couplings exponentially suppressed by the distance between different points. In the field theory limit of large compactification radii, such nonlocal couplings vanish, but they acquire nonzero values through nonpe...
متن کامل(Quantum) twisted Yangians: Symmetry, Baxterisation and centralizers
Based on the (quantum) twisted Yangians, integrable systems with special boundary conditions, called soliton non-preserving (SNP), may be constructed. In the present article we focus on the study of subalgebras of the (quantum) twisted Yangians, and we show that such a subalgebra provides an exact symmetry of the rational transfer matrix. We discuss how the spectrum of a generic transfer matrix...
