Morphing Di-Higgs processes — Ana Andrade, Anas Haddad, Philip Keicher, Tobias Kramer, •Nathan Prouvost, Marcel Rieger, Peter Schleper, and Bogdan Wiederspan — Universität Hamburg

The Standard Model of particle physics is currently the most successful theory describing our understanding of elementary particles and their interactions.

Currently, the investigation of the parameters of the Higgs mechanism is of utmost interest for tests of the predictions of the Standard Model. The trilinear higgs coupling is one such parameter. One of the challenges in the statistical interpretations of these measurements is the correct parametrisation of the distributions of the discriminating observable as a function of the coupling coefficients.

This talk summarizes a study on this topic based on a search for Di-Higgs production in the bbττ final state at the CMS experiment.
