When reclustered with R = 1.0 it acquires a large pT , mass and 1 → 2 splitting scale as it absorbs the electron. Three jets between 4 and 6 o’clock are identified with the hadronic top quark. When reclustered with R = 1.0 the three jets merge into a single jet with mj = 197 GeV, sqrt(d12) = 110, sqrt(d23) = 40.

A search for high mass resonances decaying to tau+tau- in the ATLAS detector (ATLAS-CONF-2012-067, 30 June 2012)

Figure 8: A high-MT event observed in the τhτh analysis (Run 189822, Event 86849215), which features a highly-collimated 3-prong tau candidate back-to-back with a 1-prong tau candidate that punches through to the muon spectrometer. Both tau candidates deposit significant energy in the hadronic calorimeter and have very high tau identification scores. This suggests that this is a real ditau decay (eg. a high-mass Z/γ*→τhτh event). eps, 692kB png, 5294kB

Figure 9: A high-MT event observed in the μτh analysis (Run 191920, Event 25878131), which has a forward 1-prong tau candidate with pT = 310 GeV, a forward muon with pT = 340 GeV, and ETmiss = 63 GeV. The combined MT(μ, τh, ETmiss) = 711 GeV. This event appears to be most likely a high-mass Z/γ*→μτh event. The tau candidate deposits most of its energy in the hadronic end-cap calorimeter (HEC), with an EM-fraction of only 1.5%; consistent with a 1-prong tau candidate with no π0s. The track pT = 300 GeV is consistent with the calorimeter measurement calibrated to give the tau pT. The hadronic tau candidate was energetic enough to produce hits in a single end-cap MDT station (part of the muon spectrometer), however, it does not produce a muon candidate. This signature is consistent with high energy pion punch-through. png, 2584kB
