Dualities in CHL-models

• © 2018 IOP Publishing Ltd Printed in the UK. We define a very general class of CHL-models associated with any string theory S (bosonic or supersymmetric) compactified on an internal CFT C×T d . We take the orbifold by a pair (g,δ), where g is a (possibly nongeometric) symmetry of C and δis a translation along Tn. We analyze the T-dualities of these models and show that in general they contain Atkin-Lehner type symmetries. This generalizes our previous work on N = 4 CHLmodels based on heterotic string theory on T 6 or type II on K3 × T 2 , as well.
