High Energy Physics

High energy physics involves the study of the fundamental building blocks of nature at the shortest distances. These are the fundamental particles that are described by quantum fields such as the Higgs field found at CERN's Large Hadron Collider (LHC). Our group studies theories beyond the Standard Model of particle physics both from theoretical and phenomenological perspectives.

Dyson, just before the first detection of Gravitational Waves (GWs) by LIGO, raised the question of whether the detection of a single graviton can be achieved with GW strain detectors. If this is possible, then it would be a direct evidence for the quantization of the gravitational field.

group meeting

25-11-25 was a wonderful day of celebration of past achievements, present efforts, and future horizons. It was a true joy to see so many colleagues, collaborators, and friends—who have shaped, and continue to shape, the history, present, and future of Gr@v, gathered both online and onsite. Thank you to everyone who has contributed to the first fifteen years of Gr@v during this remarkable era of strong-gravity research. We look forward to the next fifteen years!

Celebrating Strong Gravity - 25 - 11 - 25

Workshops

On November 25, 1915, Einstein presented the field equations of General Relativity to the Prussian Academy of Sciences. A hundred and ten years later, we celebrate the remarkable progress of the field of strong gravity — its many achievements, the 15th anniversary of the Aveiro Gr@v group (est. 2010), and a decade since the first detection of gravitational waves.
