Jet reconstruction and calibration in heavy-ion collisions with the ATLAS detector

Jets produced in heavy-ion collisions are one of the important hard probes that provide information about the hot and dense medium created in heavy ion collisions. The performance of the jet reconstruction is of great importance since it provides basis for each jet measurement. Due to the large underlying background and its fluctuations, the precise jet reconstruction is nontrivial and challenging. Beside the basic jet performance we concentrate namely on the methods used for the calibration of jet energy. The so-called numerical inversion used to calibrate jets in the ATLAS experiment is introduced and discussed.
