مؤلف: Toni Mäkelä

Dr. T. Mäkelä is a research scholar working in the phenomenology of high-energy physics, at the intersection of theory and experiment. His work serves to both improve our understanding of the standard model of particle physics via increased precision and to investigate the possibilities for new physics beyond the standard model.  During his doctoral studies at DESY in Hamburg, Germany, Dr. Mäkelä worked as a theorist associated with the CMS experiment. The main focus of this work is on an unbiased strategy for the simultaneous extraction of the fundamental parameters of the standard model, together with the couplings of new physics. This is performed for the first time at the Large Hadron Collider and results in the most precise extraction of the strong coupling constant at a hadron collider, at the time of writing. Furthermore, Dr. Mäkelä has carried out the first consistent investigation of the mass renormalization scale dependence of the mass of the top quark, demonstrating the importance of a proper scale choice for stabilizing the theoretical predictions for top quark–antiquark pair production cross sections, hence increasing the precision of experimental analyses.  The results of the pioneering work have been highlighted by CERN and DESY. They have also been presented at major conferences in the field of high-energy physics, as well as invited seminar talks.
