The Fast Interaction Trigger Upgrade for ALICE / Bysiak, Sebastian (Cracow, INP) /ALICE Collaboration
In preparation for the LHC Run 3 ALICE will upgrade its subsystems to cope with the increased interaction rate of 50 kHz in Pb–Pb and up to 1 MHz in other collision systems, resulting in a data throughput from the detector up to 3 TB/s. Storing and analyzing such amount of data is a significant challenge and therefore, online event selection will be required.The Fast Interaction Trigger (FIT) will generate minimum-bias and multiplicity triggers with maximum latency of 425 ns. [...]

Overview of the latest jet physics results from ALICE / Mulligan, James (LBNL, NSD ; UC, Berkeley) /ALICE Collaboration
We overview recent jet measurements in pp and Pb-Pb collisions with the ALICE detector. ALICE reconstructs jets at midrapidity using the anti-$k_{\mathrm{T}}$ algorithm, including both charged particle jets from the ALICE tracking detectors, and full jets from the combination of the ALICE electromagnetic calorimeter with the tracking system.
