[QUOTE="ofirg, post: 5483133, member: 391493"] A symmetric mass (or hermitian in the complex case) can have negative eigenvalues just not complex values. Because they are scalars they will mix with the higgs doublet scalars. There fermionic partners would mix with the fermionic partners of the higgs doublet scalars (higgsinos) It is in general not surprising that in some cases the ditau jets are more easily separated from single tau jets than from qcd jets. qcd jets are much varied in their appearance and properties. While single tau jets have specific properties, and as long as the ditau structure can be probed, it should be well separated from the single tau case. You mean figure 3 E=200 [itex]\tau_{21}[/itex]? I don't know how much this affects the result, but the I don't understand the plot. Single tau jets should have a higher [itex]\tau_{21}[/itex] like qcd jets as they have a one prong structure. Increasing systematic uncertainty will always reduce the sensitivity, obviously. In their plot the change in sensitivity is just encoded in the formula they use for the sensitivity. [/QUOTE]
