Anamaria Font, Jose Antonio Lopez
TL;DR
This paper investigates non-supersymmetric type IIB orientifolds on toroidal orbifolds, analyzing tadpole cancellation, spectra, and examples including type 0B orientifolds, to understand stability and spectrum characteristics.
Contribution
It provides a systematic analysis of tadpole conditions and spectra for non-supersymmetric orientifolds, including anti-branes and different parity actions.
Findings
Derived tadpole cancellation conditions with anti-branes.
Identified tachyonic and massless spectra for various models.
Connected certain models to type 0B orientifolds.
Abstract
We study type IIB orientifolds on T^{2d}/Z_N with supersymmetry broken by the compactification. We determine tadpole cancellation conditions including anti-branes and considering different actions for the parity Omega. Using these conditions we then obtain the spectrum of tachyons and massless states. Various examples with N even correspond to type 0B orientifolds.
