Description
Higgs pair production processes provide the direct probe to the Higgs boson self-coupling (lambda_3). However, as well known such a processes have a small production cross section. It is also known that single Higgs processes indirectly depends on lambda_3, thus an alternative method to measure the lambda_3 is considering lambda_3-dependent NLO EW corrections in single Higgs processes. The magnitude of these corrections are encoded by some process and kinematic-dependent coefficients named as C1. In the following, an overview of the determination and parametrization of the C1 coefficients and K-factors in STXS bins performed by ATLAS and CMS are shown in connection to the latest H+HH combination results with full Run2 dataset.
