My main research is focused on dark matter and, in a broader context, on topics related to the physics of the early universe.
Another field of interest is the study of the strong interaction, quantum chromodynamics, with non-perturbative methods.
Nielsen identities in Yang-Mills theory
Correlation functions, the building blocks of a quantum field theory, are gauge dependent objects. Nielsen identities are functional equations governing the gauge-parameter dependence of correlation functions in linear covariant gauges and can be used to calculate Green's functions for an arbitrary value of the gauge-fixing parameter.
