Kennesaw State physics professors will continue study of elementary particles

The beat goes on for ĪŽĀė±äĢ¬ researchers Nikolaos Kidonakis and Marco Guzzi.

The two have received their second joint grant in three years from the National Science Foundation (NSF) to advance the study of the Higgs boson ā€”also known as the ā€œGod particle,ā€ the top quark, and the proton, which are relevant to the physics program of the Large Hadron Collider (LHC) at CERN in Switzerland. This grant is a further boost for the study of theoretical particle physics at ĪŽĀė±äĢ¬. For Kidonakis, itā€™s his seventh such grant since arriving at the College of Science and Mathematics in 2004.

ā€œReceiving this grant is a confirmation that the synergy works between Nik and me, and we have been able to sustain a very competitive and strong research group here at ĪŽĀė±äĢ¬,ā€ Guzzi said. ā€œThatā€™s the other thingā€”this research is unique at ĪŽĀė±äĢ¬.ā€ In addition, their papers and studies have been among the most cited in the world among other researchers.

Their synergy comes from each researcherā€™s expertise. Kidonakis performs theoretical calculations involving the top quark, which is the heaviest known elementary particle, and the Higgs boson, which is involved in the mechanism for mass generation. Guzzi does calculations to improve our understanding of the structure of the proton and the dynamics of its internal constituents.

Their research group also focuses on undergraduates, though some of the grant funds go toward hiring postdoctoral researchers, and Kidonakis has had graduate students from other disciplines conduct research in physics. ĪŽĀė±äĢ¬ā€™s focus on undergraduate research paired with the international renown of theoretical particle physics make this research group a destination for aspiring physicists.

ā€œK³§±« promotes undergraduate research and I've been quite successful at it,ā€ Kidonakis said. ā€œI've had many students that worked with me, wrote papers with me, and gave talks and presentations at conferences and so on.ā€

In addition to the success of the research group and its individual members, Guzzi said the research truly advances the overall study of physics, putting ĪŽĀė±äĢ¬ on the map in an extremely high-level niche. That means students are getting exposed to research at an international level.

ā€œWhen you do this kind of research, you involve students, then students go to graduate school and they develop and acquire a lot of experience and they become knowledgeable about certain areas in both theoretical and computational physics,ā€ Guzzi said. ā€œAt the same time, major facilities such as the LHC at CERN, require the expertise of many peopleā€”engineers, physicists, technicians. Therefore, this research is a true advancement for training young people in STEM disciplines.ā€

The grantā€™s three-year period ends in 2027, but the research groupā€™s track record of continuing their work, engaging undergraduates, publishing papers (well over a hundred under the various NSF grants so far), and getting resultsā€”along with the constantly evolving nature of scienceā€”means the two professors will have plenty of work to do as the years go by. Each said he truly enjoys what he does and acknowledges the dynamic nature of physics, meaning the true finish line is always a few yards ahead.

ā€œScience never ends, so of course it always keeps moving,ā€ Kidonakis said. ā€œThere can be an end point for something specific like a calculation, but there are always other things you can do or improve.ā€
