Non-split singularities and conifold transitions in F-theory
Rinto Kuramochi, Shun'ya Mizoguchi, Taro Tani
In F-theory, if a fiber type of an elliptic fibration involves a condition that requires an exceptional curve to split into two irreducible components, it is called ``split'' or ``…
Magic square and half-hypermultiplets in F-theory
Rinto Kuramochi, Shun'ya Mizoguchi, Taro Tani
In six-dimensional F-theory/heterotic string theory, half-hypermultiplets arise only when they correspond to particular quaternionic Kähler symmetric spaces, which are mostly assoc…
Half-hypermultiplets and incomplete/complete resolutions in F-theory
Naoto Kan, Shun'ya Mizoguchi, Taro Tani
We consider resolutions of codimension-two enhanced singularities from to and from to in six-dimensional F-theory, where a half-hypermultiplet arises for…
Non-Cartan Mordell-Weil lattices of rational elliptic surfaces and heterotic/F-theory compactifications
Shun'ya Mizoguchi, Taro Tani
The Mordell-Weil lattices (MW lattices) associated to rational elliptic surfaces are classified into 74 types. Among them, there are cases in which the MW lattice is none of the we…
Anomaly-free Multiple Singularity Enhancement in F-theory
Shun'ya Mizoguchi, Taro Tani
We study global Calabi-Yau realizations of multiple singularity enhancement relevant for family-unification model building in F-theory. We examine the conditions under which the ge…
