Along with the remarkable success of the Standard Model of particle physics, there are compelling reasons to consider that at higher energy scales the Standard Model requires an extension into a more fundamental theory. One of the most promising channels for searches of New Physics is the study of of electroweak boson-pairs production. New phenomena could manifest in diboson final states either as a modification of the coupling strength (anomalous couplings) or as resonances in the diboson invariant mass spectrum. A precise knowledge of the Standard Model diboson production cross-sections is therefore necessary for searches of New Physics in the electroweak sector. The ATLAS experiment at the LHC has developed a comprehensive diboson physics program to further explore this frontier. In this talk the recent ATLAS diboson results will be discussed. The focus of the talk will be on precision measurements of diboson processes and interpretations of these measurements for searches for physics beyond the Standard Model.

Dr. Elena Yatsenko has obtained her PhD at DESY in Germany with the ATLAS experiment, where she has workedon measurements of the Drell-Yan production cross-section and forward-backward asymmetry, and studied the impactof the Drell-Yan processes to the QCD fits of the proton PDFs. She has continued to work with the ATLAS detectorin her postgraduate research at LAPP, France, where she has focused on the diboson physics and got involved to theperformance and data preparation studies with the ATLAS liquid argon calorimeter. Currently she is postdoc at SJTUand TDLI, where she continue the investigation of the diboson physics with the ATLAS detector.
