    • F-theory on quotient threefolds with (2,0) discrete superconformal matter 

      Anderson, Lara B.; Grassi, Antonella; Gray, James; Oehlmann, Paul-Konstantin (Springer, 2018-06-20)
      We explore 6-dimensional compactifications of F-theory exhibiting (2, 0) superconformal theories coupled to gravity that include discretely charged superconformal matter. Beginning with F-theory geometries with Abelian ...
    • An F-theory realization of the chiral MSSM with Z(2)-parity 

      Cvetič, Mirjam; Lin, Ling; Liu, Muyang; Oehlmann, Paul-Konstantin (Springer, 2018-09-17)
      Using F-theory we construct 4D N = 1 SUGRA theories with the Standard Model gauge group, three chiral generations, and matter parity in order to forbid all dimension four baryon and lepton number violating operators. The ...
    • Modular curves and Mordell-Weil torsion in F-theory 

      Hajouji, Nadir; Oehlmann, Paul-Konstantin (2020-04-16)
      In this work we prove a bound for the torsion in Mordell-Weil groups of smooth elliptically fibered Calabi-Yau 3- and 4-folds. In particular, we show that the set of torsion groups which can occur on a smooth elliptic ...
    • Mordell-Weil torsion in the mirror of multi-sections 

      Oehlmann, Paul-Konstantin; Reuter, Jonas; Schimannek, Thorsten (Springer, 2016-12-12)
      We give further evidence that genus-one fibers with multi-sections are mirror dual to fibers with Mordell-Weil torsion. In the physics of F-theory compactifications this implies a relation between models with a non-simply ...
