[3] For six years he was a member of the research group of Carlo Rubbia, that made essential contributions to the physics of CP violation in the neutral kaon sector.

The discovery led to the 1984 Nobel Prize in Physics being awarded to Carlo Rubbia and Simon van der Meer for their decisive contributions to the design and construction of the proton-antiproton collider.

[8] Prior to the discovery the UA2 collaboration made the first observation of emission of quarks and gluons in the form of hadronic jet – an important experimental support of the theory of quantum chromodynamics.

[9] From 1987 to 1994 Darriulat held the position as Research Director at CERN, during which time the Large Electron–Positron Collider (LEP) began its operation.

Subsequent, Darriulat turned to solid state physics, conducting research in the field of superconductivity on the property of niobium films.
