Description
At the CERN LHC, instantaneous luminosities of up to 1.5× 1034 cm− 2 s− 1 [1] are sufficiently large for multiple proton-proton (pp) collisions to occur in the same time window in which proton bunches collide. This leads to overlapping of particle interactions in the detector. To study a specific pp interaction, it is necessary to separate this single interaction from the overlapping ones. The additional collisions, known as pileup (PU), will result in additional particles throughout the detector that confuse the desired measurements. With PU mitigation techniques, we can minimize the impact of PU and better isolate the single collision of interest. With increasing beam intensity over the past several years, identification of interesting pp collisions has become an ever-growing challenge at the LHC. The number of additional collisions that occur when two proton bunches collide was, on average, 23 in 2016 and subsequently …
