Probing CPV with DPhijj in H to WW / Clarry, Cameron (University of Toronto (CA)) ; Marr, Metea Castilleja (Simon Fraser University (CA)) ; Basso, Matthew Joseph (TRIUMF (CA)) /ATLAS Collaboration
The Simplified Template Cross Section (STXS) scheme offers a practical structure for performing Higgs boson measurements. The binning scheme only makes use of CP-even observables however, leaving it insensitive to CP-odd couplings of the Higgs. [...]

Exploring the CP-sensitive STXS staging in the H→WW* decay channel by the ATLAS experiment / Marr, Metea Castilleja (Simon Fraser University (CA)) ; Basso, Matthew Joseph (TRIUMF (CA)) /ATLAS Collaboration
The current STXS Stage 1.2 binning is not sensitive to the charge-parity properties of the Higgs boson. Parallel to the ongoing effort to finalize the STXS Stage 1.3 bins, the ATLAS experiment has studied the potential for measuring CP-sensitive STXS-like bins the $H\rightarrow WW^\ast$ decay channel. [...]

STXS binnings for CP sensitivity (20'+10') / Winter, Benedict Tobias (speaker) (Albert Ludwigs Universitaet Freiburg (DE))
The current Simplified Template Cross-Section (STXS) categorization leaves STXS analyses insensitive to CP-odd contributions in Higgs boson production, which are predicted by several models beyond the Standard Model. This presentation proposes to categorize events with two jets additionally via the dPhijj observable to make future Run 2+3 analyses sensitive to CP violation [...]

Measurements of gluon fusion and vector-boson-fusion production of the Higgs boson in $𝐻\rightarrow𝑊𝑊^{*}→𝑒\nu\mu \nu$ decays using 13 TeV $pp$ collisions with the ATLAS detector  / Hayes, Robin (University of British Columbia (CA)) /ATLAS Collaboration
Measurements of the Higgs boson’s production cross-sections are an important probe of physics beyond the Standard Model (SM). At CERN’s Large Hadron Collider (LHC), these measurements are challenging due to the high-background environment, where on average fewer than one in one billion proton-proton collisions produce Higgs bosons.

Measurements of Standard Model Higgs Decays to Bosons with ATLAS and CMS / Basso, Matthew Joseph (University of Toronto (CA)) /ATLAS Collaboration
We present an overview of recent precision measurements of Standard Model Higgs decays to bosons performed by ATLAS and CMS using the LHC's full Run 2 dataset. This overview includes measurements of coupling strength modifiers and Simplified Template Cross Sections (STXS) in the $H\rightarrow WW^\ast$, $H\rightarrow ZZ^\ast$, $H\rightarrow \gamma\gamma$, and $H\rightarrow Z\gamma$ decay channels.

Measurements of the CP structure of Higgs boson couplings with the ATLAS detector / Basso, Matthew Joseph (TRIUMF (CA)) /ATLAS Collaboration
While the Standard Model predicts that the Higgs boson is a CP-even scalar, CP-odd contributions to the Higgs boson's interactions with vector bosons or fermions are presently not strongly constrained. A variety of Higgs boson production processes and decays can be used to study the CP nature of the Higgs boson interactions. [...]
