Measurement of jet quenching with semi-inclusive hadron-jet distributions in central Pb-Pb collisions at sNN=2.76 TeV

A bstract We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at s N N = 2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high- p T ) charged hadron trigger. Jets are measured using collinear-safe jet reconst...

Zusammenfassung:	A bstract We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at s N N = 2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high- p T ) charged hadron trigger. Jets are measured using collinear-safe jet reconstruction with infrared cutoff for jet constituents of 0.15 GeV, for jet resolution parameters R = 0 . 2, 0 . 4 and 0 . 5. Underlying event background is corrected at the event-ensemble level, without imposing bias on the jet population. Recoil jet spectra are reported in the range 20
