We reproduce all invariant mass distributions and asymmetries in
hep-ph/0507170.
For illustration, here we show our results for asymmetries and dielpton invariant mass distributions in the squark or KK-quark decay for both narrow (UED500) and broad (SPS1a) mass spectrum, as well as the same results from
hep-ph/0507170 .
Asymmetry for narrow mass spectrum (UED500)
 
Asymmetry for broad mass spectrum (SPS1a)
 
Dilepton invariant mass for narrow mass spectrum (UED500)
 
Dilepton invariant mass for broad mass spectrum (SPS1a)
