Constraints on UED from W' searches

Understand

We obtain contraints on three Universal Extra Dimensional models utilizing limits from the CMS Collaboration on W' production and decay into a single-top-quark final state.

• We find a weak constraint on the Minimal Universal Extra Dimensions model due to small Kaluza-Klein number violating terms.
• In contrast, the W' search puts a strong limit on the size of the Dirac mass term of the quarks in Split Universal Extra Dimension models.
• In Non-minimal Universal Extra Dimension models the W' search constrains the splitting between the boundary localized kinetic terms of the gauge bosons and the quarks.
