Development of new approach to study particle correlations using femtoscopy
One of the most precise and most powerful approaches to probe the strong interaction between different particle pairs is the femtoscopy method [1] which is based on measuring the correlation in the momentum space between hadrons produced at particle colliders such as the LHC. The correlation function is obtained by using the same and mixed event particle pair distributions as functions of their relative momenta. The former carries the information about the interaction while the latter provides information on the available phase-space of the produced pair. Two particles produced in one collision makes the same event pair while the mixed event pairs are constructed by taking two particles from two di erent collisions. The technique of event mixing is a very well working approximation, however, more sophisticated solutions are of increasing interest as the femtoscopic method is used in more and more complicated studies and is being extended to probe the multi-hadron interactions. In this work, a new approach to account for the particle phase space will be elaborated by using marginalized probability distribution functions. Toy Monte Carlo simulations will be used to test the mathematical basis of the method which will be then applied on the proton-proton collision data collected by the ALICE detector to study its feasibility in real experimental conditions.
