F-theory on 6D Symmetric Toroidal Orbifolds

Understand

In this work we study F-theory on symmetric toroidal orbifolds that exhibit roto-translations, which are point group rotations accompanied by fractional lattice shifts.

• These geometries admit a rich class of effects, such as twisted affine folded fibers, multiple fibers, and up to three distinct torus-fibrations that yield different M/F-theory lifts.
• We discuss the six-dimensional physics of the F-theory lifts, which generically host superconformal subsectors and a IIB axio-dilaton fixed to strong coupling.
• In addition we find that these theories exhibit a rich set of p=0,1,2 discrete p-form gauge symmetries.
