asymmetry in wbf jets
Asked by
Johan Alwall
Hey guys,
when looking at the WBF-process p p > j j mu+ mu- /h QED=4 QCD=0 with a cut on the invariant muon mass between 118.4GeV and 121.6GeV (additionally to the standard cuts) one ends up with a cross-section several orders of magnitude below the corresponding SHERPA-result (0.33fb - which we confirmed to be right).
Furthermore if one looks into the pseudorapidity distribution of the two jets, one finds that they are not symmetric around eta=0, but that the leading jet prefers the negative and the second the jet accordingly the positive direction (i.e. hemisphere of the detector).
cheers
Daniel
