"A Tale of Two Theories: Searches for Higgs Pair Production with the ATLAS Detector"


Ben Tannenwald , Ohio State University
[Host: Chris Neu]
ABSTRACT:

A new era in experimental particle physics began with the 2012 discovery of the Higgs boson by the ATLAS and CMS Collaborations. Multiple measurements have since shown the new boson possesses several properties (spin, parity, gauge couplings) consistent with the Standard Model, but many characteristics remain unknown. The nature of the Higgs self-coupling is currently unmeasured, and a precise understanding of this interaction would provide stringent new tests of the Standard Model Higgs sector. Searches for Higgs pair production have the power to confirm Standard Model predictions and help map the shape of the Higgs potential or provide a window into new physics beyond our current understanding. This seminar will summarize recent searches for Higgs pair production using the ATLAS detector. Constraints on exotic physics models will be presented and an outlook on future improvements will be discussed.
