A class of non-supersymmetric orientifolds
نویسندگان
چکیده
We study type IIB orientifolds on T/ZN with supersymmetry broken by the compactification. We determine tadpole cancellation conditions including antibranes and considering different actions for the parity Ω. Using these conditions we then obtain the spectrum of tachyons and massless states. Various examples with N even correspond to type 0B orientifolds.

Aspects of Type 0 String Theory
A construction of compact tachyon-free orientifolds of the non-supersymmetric Type 0B string theory is presented. Moreover, we study effective non-supersymmetric gauge theories arising on self-dual D3-branes in Type 0B orbifolds and orientifolds.
متن کاملAnomaly Free Non-Supersymmetric Large N Gauge Theories from Orientifolds
We construct anomaly free non-supersymmetric large N gauge theories from orientifolds of Type IIB on C/Γ orbifolds. In particular, massless as well as tachyonic one-loop tadpoles are cancelled in these models. This is achieved by starting with N = 1, 2 supersymmetric orientifolds with well defined worldsheet description and including discrete torsion (which breaks supersymmetry) in the orbifold...
متن کاملSupersymmetric Three Family SU(5) Grand Unified Models from Type IIA Orientifolds with Intersecting D6-Branes
We construct some N = 1 supersymmetric three-family SU(5) Grand Unified Models from type IIA orientifolds on T6/(Z2 × Z2) with D6-branes intersecting at general angles. These constructions are supersymmetric only for special choices of untwisted moduli. We show that within the above class of constructions there are no supersymmetric three-family models with 3 copies of 10-plets unless there are...
متن کاملNon-perturbative Orientifolds
We consider non-perturbative six and four dimensional N = 1 space-time supersymmetric orientifolds. Some states in such compactifications arise in “twisted” open string sectors which lack world-sheet description in terms of D-branes. Using Type I-heterotic duality we are able to obtain the massless spectra for some of such orientifolds. The four dimensional compactification we discus in this co...
متن کاملTachyon-free Orientifolds of Type 0B Strings in Various Dimensions
We construct non-tachyonic, non-supersymmetric orientifolds of type 0B strings in ten, six and four space-time dimensions. Typically, these models have unitary gauge groups with charged massless fermionic and bosonic matter fields. However, generically there remains an uncancelled dilaton tadpole.
