Measurement of the SM Higgs boson mass in the diphoton and 4l decay channels using the ATLAS detector

One of the fundamental properties of the Higgs boson, it's mass, is measured by way of studying the invariant mass of the 4l and diphoton decay channels with about 36fb-1 of data collected by the ATLAS experiments. Since in this channel the final state can be reconstructed as invariant mass peak with a good experimental resolution this measurement can be done in a model independent way and used as an input to compare other measurement properties with the SM predictions.
