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.

Two research grants in Strong Gravity/HEP for M.Sc. holders

A call for two 10 months research grants in Strong Gravity/High Energy Physics, for M.Sc. holders enrolled in a doctoral programme at Aveiro University, within the research grant “Testing the Kerr hypothesis with gravitational waves and lensing", PTDC/FIS-AST/3041/2020, is open from 1 to 20 December 2021.  See attached document for details (in Portuguese) or the Euraxess announcement (in Portuguese and English) here.

Correlations play a fundamental role in many branches of physics, from quantum mechanics to particle physics and cosmology. In particular, the astonishing homogeneity of the angular distribution of the Cosmic Microwave Background radiation across the sky (measured with high precision by the WMAP and Planck missions) requires of an inflationary epoch right after the Big Bang.
