A Review on Non-Minimal Universal Extra Dimensions
  We report on the current status of non-minimal universal extra dimension (UED) models. Our emphasis is on the possible extension of the minimal UED model by allowing bulk masses and boundary localized terms. We take into account the data from the Large Hadron Collider as well as direct and indirect searches of dark matter and electroweak precision measurements.
