Measurement of colour flow with the jet pull angle in tt events using the ATLAS detector at s = 8 TeV
Original language description
The distribution and orientation of energy inside jets is predicted to be an experimental handle on colour connections between the hard-scatter quarks and gluons initiating the jets. This Letter presents a measurement of the distribution of one such variable, the jet pull angle. The pull angle is measured for jets produced in tt events with one W boson decaying leptonically and the other decaying to jets using 20.3 fb 1 of data recorded with the ATLAS detector at a centre-of-mass energy of s=8 TeV at the LHC. The jet pull angle distribution is corrected for detector resolution and acceptance effects and is compared to various models.
