Report

Autor: Heiner, Matthew J., Johnson, Samuel B., Christensen, Joshua R., Dahl, David B.

We propose and demonstrate an alternate, effective approach to simple slice sampling. Using the probability integral transform, we first generalize Neal's shrinkage algorithm, standardizing the procedure to an automatic and universal starting point:

Enhanced gauge symmetry in 6D F-theory models and tuned elliptic Calabi-Yau threefolds

Autor: Johnson, Samuel B., Taylor, Washington

We systematically analyze the local combinations of gauge groups and matter that can arise in 6D F-theory models over a fixed base. We compare the low-energy constraints of anomaly cancellation to explicit F-theory constructions using Weierstrass and

Calabi-Yau threefolds with large h^{2, 1}

Autor: Johnson, Samuel B., Taylor, Washington

We carry out a systematic analysis of Calabi-Yau threefolds that are elliptically fibered with section ("EFS") and have a large Hodge number h^{2, 1}. EFS Calabi-Yau threefolds live in a single connected space, with regions of moduli space associated
