Hello Mariel, 

nice talk, only a few comments:

Slide 3: The placement of the label on the plot is a bit unfortunate, as it covers part of th e plot. 

Slide 8: The acronym "LCW" might not be understood outside of ATLAS. 

- Walter

Very nice talk!  Just one minor comment: I think you *could* skip slide 2, if you want.  This conference is HEP and related folks, so they should be familiar with ATLAS.  But I could also understand why you want to go over this, since your talk is somewhat technical and depends on the details of the detector.
