Study of Jet Shapes in Inclusive Jet Production in pp Collisions at sqrt(s) = 7 TeV using the ATLAS Detector

The ATLAS Collaboration

Understand

Jet shapes have been measured in inclusive jet production in proton-proton collisions at sqrt(s) = 7 TeV using 3 pb^{-1} of data recorded by the ATLAS experiment at the LHC.

Jets are reconstructed using the anti-kt algorithm with transverse momentum 30 GeV < pT < 600 GeV and rapidity in the region |y| < 2.8.
The data are corrected for detector effects and compared to several leading-order QCD matrix elements plus parton shower Monte Carlo predictions, including different sets of parameters tuned to model fragmentation processes and underlying event contributions in the final state.
The measured jets become narrower with increasing jet transverse momentum and the jet shapes present a moderate jet rapidity dependence.

Inclusive jet shape studies have a very limited sensitivity to the presence of a small contribution from heavy-flavor quarks in the final state

The ATLAS reference system is a Cartesian right-handed coordinate system, with the nominal collision point at the origin. The anti-clockwise beam direction defines the positive z z -axis, while the positive x x -axis is defined as pointing from the collision point to the centre of the LHC ring and the positive y y -axis points upwards. The azimuthal angle ϕ \phi is measured around the beam axis, and the polar angle θ \theta is measured with respect to the z z -axis. The pseudorapidity is defined as η = − ln ⁡ ( tan ⁡ ( θ / 2 ) ) \eta=-{\rm ln}({\rm tan}(\theta/2)) . The rapidity is defined as y = 0.5 × ln ⁡ [ ( E + p z ) / ( E − p z ) ] y=0.5\times{\rm ln}[(E+p_{z})/(E-p_{z})] , where E E denotes the energy and p z p_{z} is the component of the momentum along the beam direction
