Studying high energy limit of Quantum Chromodynamics

Description:

Perturbative Quantum Chromodynamics is a tool to study the structure of protons and nuclei. In the limit of high energies of the collision (small Bjorken-x), it allows us to the phenomenon called parton saturation, where the structure of proton is given as dynamical balance between radiation and recombination processes, which leads to the suppression of growth in the number of gluons. The behavior of the gluon distributions in this limit is described via the Balitsky-Kovchegov equation (BK), an integro-diferential equation with divergent kernel. Since there is no analytic method for solving the BK equation, one has to do it numerically. Complementary to that, the particle composition of proton as quantum particle can fluctuate. This can be addressed by combining the solution of BK equation with the use of a randomly generated profile using gluonic (hot) spots inside the proton. 

The topic focuses on the solution of the BK equation in its full form and combining this solution with the initial conditions generated via the hot spot model. This combined model will then be used to calculate observables. Using measured data for these observables, one can fit the parameters for this model so that the model can be used to predict future measurements. In order to do that a sophisticated fitting method has to be implemented, e.g. using KAN neural networks.
Note that this call is only for funding. Students also have to apply to our PhD program (Nuclear Engineering, see details at https://fjfi.cvut.cz/en/applicants/doctoral-studies/admission-procedure… ). Note that the deadline to apply to the PhD program is May 21st.
