CMB lensing is a promising, novel way to measure galaxy cluster masses thatcan be used, e.g., for mass calibration in galaxy cluster counts analyses.Understanding the statistics of the galaxy cluster mass observable obtainedwith such measurements is essential if their use in subsequent analyses is notto lead to biased results. We study the statistics of a CMB lensing galaxycluster mass observable for a Planck-like experiment with mock observationsobtained from an N-body simulation. We quantify the bias and intrinsic scatterassociated with this observable following two different approaches, one inwhich the signal due to the cluster and nearby correlated large-scale structureis isolated, and another one in which the variation due to uncorrelatedlarge-scale structure is also taken into account. For our first approach wealso quantify deviations from log-normality in the scatter, finding them tohave a negligible impact on mass calibration for our Planck-like experiment. Webriefly discuss how some of our results change for experiments with higherangular resolution and lower noise levels, such as the current generation ofsurveys obtained with ground-based, large-aperture telescopes.
