 \nSpeaker: Benjamin Percival （University of Liverpool)\nTitle: Moduli F
 ixing and D-term Uplifts of One-loop Potentials in Non-Supersymmetric Hete
 rotic String Models\n\nAbstract: Within the free fermionic classification 
 methodology of Z2 × Z2 heterotic strings\, different avenues towards non-
 supersymmetric models are discussed. Some aspects of classifying asymmetri
 c models are discussed\, in particular the relation of moduli fixing to ob
 taining certain desirable phenomenological criteria. We explain the method
 ology that allows for the analysis of the Fayet-Iliopoulos D-term and the 
 one-loop potential for such models\, first for symmetric Z2 x Z2 orbifolds
  and then how this can be extended to the asymmetric case in which some in
 ternal moduli are fixed. We show examples of Z2 x Z2 non-supersymmetric sy
 mmetric orbifolds that exhibit a D-term uplift of their one-loop potential
 . We demonstrate this for models both in which the SUSY is broken spontane
 ously via Scherk-Schwarz\, as well as explicit breaking.\n\nhttps://indico
