Results in brief
Hard probes of heavy-ion collisions
In the big picture, the project tries to help understand the behavior of our nature at the most fundamental level. The obtained results improve our understanding of the matter that is believed to have existed during the first microseconds after the Big Bang or in the cores of neutron stars. Heavy ion collisions are currently the only way to create and study such extreme conditions on Earth. Secondly, the project results should help us understand the process of how heavy particles, like protons and neutrons, are formed from quarks, which are the most fundamental building blocks of matter we know. More specifically, this project aims to improve our understanding of properties and states of matter at extremely high temperatures and pressures that existed shortly after the Big Bang. Such conditions can be created by collisions of two heavy nuclei at ultra-relativistic energies. The project also tries to improve our knowledge of one of the four fundamental forces in nature, the strong interaction. This is done by measurement of hard processes like jets, collimated sprays of particles that are born in collisions and penetrate the hot and dense plasma. In conclusion, the result of this project provides a new perspective for understanding the role of jet structure, jet mass, jet flavor, and path length in jet suppression in the hot and dense medium, quark-gluon plasma. This can be further used by theorists in constraining plasma properties as we ll as improve our understanding of the strong force.

Project objective
Heavy-ion collisions at collider energies are performed in order to produce and study QCD matter at high temperature, the quark-gluon plasma (QGP). Such an extreme state of matter is believed to have existed during the first microseconds after the Big Bang. The QGP and properties of strong force can be probed on a variety of length scales by jets, collimated spraysof particles originating from scattered quarks and gluons. The intent of this proposal is to study how high-energy quarks and gluons interact with the QGP and to better understand the mechanism of energy loss as they traverse the QGP. The investigators will focus on studies of jet substructure using contemporary substructure techniques as well as exploiting the role of flavour, jets size, and path-length dependence using new probes involving boosted objects. The project includes both experimental measurements and phenomenological investigations using existing models and their improvement.
