Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector will receive damage from non-ionizing radiation in excess of 10(15) 1 MeV n(eq)/cm(2), while the pixel detector designed for the high-luminosity LHC must cope with an order of magnitude larger fluence. This paper presents a digitization model incorporating effects of radiation damage to the pixel sensors. The model is described in detail and predictions for the charge collection efficiency and Lorentz angle are compared with collision data collected between 2015 and 2017 (<= 10(15) 1 MeV n(eq)/cm(2)).", optnote="WOS:000472134700001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4063), last updated on Wed, 03 Jul 2019 12:29:39 +0000", issn="1748-0221", doi="10.1088/1748-0221/14/06/P06012", opturl="https://arxiv.org/abs/1905.03739", opturl="https://doi.org/10.1088/1748-0221/14/06/P06012", language="English" }
