Bound on minimal universal extra dimensions from B̄→Xsγ
We reexamine the constraints on universal extra dimensional models arising from the inclusive radiative B̄→Xsγ decay. We take into account the leading order contributions due to the exchange of Kaluza-Klein modes as well as the available next-to-next-to-leading order corrections to the B̄→Xsγ branch...

| description | We reexamine the constraints on universal extra dimensional models arising from the inclusive radiative B̄→Xsγ decay. We take into account the leading order contributions due to the exchange of Kaluza-Klein modes as well as the available next-to-next-to-leading order corrections to the B̄→Xsγ branching ratio in the standard model. For the case of one large flat universal extra dimension, we obtain a lower bound on the inverse compactification radius 1/R>600GeV at 95% confidence level that is independent of the Higgs mass. © 2007 The American Physical Society. |
