Research
The discovery of the Higgs boson was a triumph of the Standard Model (SM) of Particle Physics. However, the SM cannot be the final theory of nature because many observed phenomena, such as dark matter, are not explained by the SM. New theories have been proposed to address the shortcomings of the SM, but no evidence for them has been found yet. In this context, the Higgs boson provides a unique opportunity to test the SM, to see when and if it breaks down, and to probe new laws of physics.
The Higgs boson is the only elementary particle that can establish if nature allows particles to interact with themselves. This is one of the most fundamental interactions that elementary particles can have. How does the Higgs boson interact with itself? And is this the only Higgs boson? Both of these most profound questions in physics can be answered by searching for events with pair-produced Higgs boson. In order to achieve this, I have pioneered techniques to analyse proton-proton collision data at the LHC. In the coming years, we will either find an enhancement of the rate of Higgs pair production compared to SM prediction, which will be a tell-tale sign of new laws of physics, or else we will set the world's most stringent constraints on what the new laws of physics should be.
Publications
I am a member of the ATLAS collaboration, which publishes about 100 papers each year. To many of these, I contribute through data-taking operations, trigger performance studies, detector calibration and simulation, student & postdoc supervision, and executing other responsibilities. However, below is a list of publications where I have made major contributions.
