Conflicts with de Sitter Vacua in Superstring Theory

McGill Science Undergraduate Research Journal
Models of our universe lack consistency at different energy scales, so we require a theory with ultraviolet (UV) completion such as string theory. A suitable candidate to model our universe in this framework is de Sitter space, a spacetime which expands and has positive curvature.

DWSB for heterotic flux compactifications

, 2011
We investigate the construction of non-supersymmetric vacua in compactifications of heterotic string theory with intrinsic torsion and background fluxes. We do this by using the technique of domain-wall supersymmetry breaking (DWSB) that was developed in

O(d,d;R) Deformations of Complex Structures and Extended Worldsheet Supersymmetry

, 1994
It is shown that the O(d,d;R) deformations of the superstring vacua and the O(d,d+16;R) deformations of the heterotic string vacua preserve extended worldsheet supersymmetry and, hence, generate superconformal deformations.

Z' Physics and Supersymmetry

, 1997
We review the status of heavy neutral gauge bosons, Z', with emphasis on constraints that arise in supersymmetric models, especially those motivated from superstring compactifications.

Orientifold Calabi-Yau threefolds: divisor exchanges and multi-reflections

Journal of High Energy Physics
Using the Kreuzer-Skarke database of 4-dimensional reflexive polytopes, we systematically constructed a new database of orientifold Calabi-Yau threefolds with h 1,1(X) ≤ 12.

Emergence of CY triple intersection numbers in M-theory

Journal of High Energy Physics
To give more credence to the M-theoretic Emergence Proposal it is important to show that also classical kinetic terms in a low energy effective action arise as a quantum effect from integrating out light towers of states.
