We report various energy reconstruction algorithms used by the CMS hadron calorimeter (HCAL) during Run 2 of the LHC. During Run 2 of the LHC, the characteristic bunch-crossing spacing for proton-proton collision was 25 ns, which resulted in overlapping signals from adjacent crossings. The energy corresponding to a particular bunch crossing can be estimated using the known pulse shapes of energy depositions in the calorimeter. In this document, we describe the performance of the algorithms that were developed to mitigate the effects of adjacent bunch crossings on local HCAL energy reconstruction in Run 2.
