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.
For our latest developments/activities in this area, please see the listing below.
By solving the Einstein's field equations, we derive several
configurations of compact objects with a nucleus of exotic energy in a
static and spherically symmetric spacetime. In this talk I describe the
derivation and several properties of the configurations, including the
fact that in some of these objects can be reached a compacity as close to
P. Cunha and C. Herdeiro were invited speakers at the online workshop on numerical and analytical relativity (NAR-2024), organized by the Department of Applied Sciences, Indian Institute of Information Technology Allahabad (IIITA) during 20 - 22 March 2024. The video recorded lectures can be seen here.
Composite Higgs Models are still viable extensions of the Standard Model. I will first review the basic idea of this class of models.
Numerical Relativity is a key tool for the study of strong-field gravity. I will present a new evolution code, based on the Kadath library. It relies on multidomain spectral methods for the space discretization, and explicit time integration schemes.
