With the rapidly increasing proton-proton collision data-set provided by the Large Hadron Collider (LHC), the ATLAS experiment gains access to rare, but particularly interesting Higgs boson signatures. In my talk, I will discuss two distinctive and highly relevant ones: 

1. Looking for Higgs bosons produced with ever higher momenta. Measurements in this phase space are well motivated by a vast variety of new theories which predict effects that scale with the square of the involved energy scale.

 

2. Determining the shape of the Higgs potential through searches for Higgs boson pair production.
 

I will motivate the measurements within the broader particle physics landscape, and explain the main experimental difficulties that have to be overcome for these analyses to succeed. A special focus will be placed on the opportunities that the future promises and the upgrade that the ATLAS inner tracker needs to undergo in light of the High Luminosity LHC. Along these lines, a novel measurement of the material budged of an ATLAS upgrade pixel module will be presented.
