Description
We investigate Ftheory on an elliptic CalabiYau 4fold without a section to the fibration. To construct an elliptic CalabiYau 4fold without a section, we introduce families of elliptic K3 surfaces which do not admit a section. A product K3 × K3, with one of the K3’s chosen from these families of elliptic K3 surfaces without a section, realises an elliptic CalabiYau 4fold without a section. We then compactify Ftheory on such K3 × K3’s. We determine the gauge groups and matter fields which arise on 7branes for these models of Ftheory compactifications without a section. Since each K3 × K3 constructed does not have a section, gauge groups arising on 7branes for Ftheory models on constructed K3 × K3’s do not have U(1)part. Interestingly, exceptional gauge group E6 appears for some cases.
