We use the combined action of Z2-chiral reflections (T-dualities) and shifts to build N= 1,2 supersymmetric four-dimensional string compactifications with few moduli. In particular, we consider Z2^4 asymmetric orbifolds of Type IIB on the maximal torus of SO(12) that mimic N = 2 Calabi-Yau compactifications with small ``effective'' Hodge numbers starting from (h11,h21) = (1,1). We analyze possible unoriented projections, providing Type I examples with or without open strings. N = 1 oriented asymmetric shift-orbifolds of Type IIB with few chiral multiplets are also presented.

Abstract
We use the combined action of Z2-chiral reflections (T-dualities) and shifts to build N= 1,2 supersymmetric four-dimensional string compactifications with few moduli. In particular, we consider Z2^4 asymmetric orbifolds of Type IIB on the maximal torus of SO(12) that mimic N = 2 Calabi-Yau compactifications with small ``effective'' Hodge numbers starting from (h11,h21) = (1,1). We analyze possible unoriented projections, providing Type I examples with or without open strings. N = 1 oriented asymmetric shift-orbifolds of Type IIB with few chiral multiplets are also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
