About

Kostas Nikolopoulos is a particle physicist working on the ATLAS experiment at CERN.

Kostas’ research is focused on the experimental study of electroweak symmetry breaking, which in the Standard Model (SM) of particle physics is connected to the appearance of the Higgs boson. He led the ATLAS H→ZZ group between October 2010 and October 2012, in the effort that resulted in the discovery of a SM-like Higgs boson. Currently, his research is focusing in the detailed study of the properties of the newly observed particle.

Qualifications

 

  • PhD in Particle Physics, University of Athens, 2010

Biography

Kostas Nikolopoulos obtained his Ph.D. on the ATLAS experiment with the University of Athens (Greece) in 2010. His thesis was awarded Marc Virchaux Prize. Subsequently, he joined the Brookhaven National Laboratory (USA) as a post-doctoral research associate, and since 2012 he joined the University of Birmingham as a Birmingham Fellow

Since October 2010, he is leading the ATLAS  H→ZZ group, consisting of approximately 100 physicists working in the search for the Higgs boson in the decay channels involving Z bosons. His term of office was exceptionally extended for an additional year in October 2011.
