Strategies and obstacles in constructing realistic higher-dimensional models
Bohdan Grzadkowski, Jose Wudka
We discuss several aspects of higher dimensional models that contain bulk gauge and fermion fields only. In particular we argue that non-standard boundary conditions involving char…
KK Gravitons and Unitarity Violation in the Randall-Sundrum Model
Bohdan Grzadkowski, John F. Gunion
We show that perturbative unitarity for scattering places significant constraints on the Randall-Sundrum theory with two 3-branes, with matter confined to the TeV brane. T…
5-Dimensional Difficulties of Gauge-Higgs Unifications
Bohdan Grzadkowski, Jose Wudka
We consider 5 dimensional gauge theories where the 5th direction is compactified on the orbifold S^1/Z_2, and where the 5th components of the gauge bosons play the role of the Stan…
New-Physics Search through gamma gamma -> t tbar -> lX/bX
Bohdan Grzadkowski, Zenro Hioki, Kazumasa Ohkuma +1
We probe optimal beam polarizations for new-physics search in top-quark and Higgs-boson sectors at Photon Linear Colliders (PLC). Expressing possible non-standard effects generated…
