The perspective of selected studies of multiquark exotic hadrons is discussed. The topic includes detailed analysis of their strong, weak and electromagnetic decays containing charmed quark and charmed quark-antiquark pair, physics analysis and events reconstruction in pp\bar, pp and proton-nuclei collisions. These provide a good opportunity to test the theories of strong interactions including both perturbative and non-perturbative QCD, lattice QCD, potential and phenomenological models
Tasks
The aim of the project deals with study of exotic multiquark states containing charmed quark-antiquark component in application to:
- p̅p interactions with √s up to 5.5 GeV
- pp collisions with √s up to 27 GeV
- pA collisions with √s up to 11 GeV
Preliminary schedule by topics/tasks
1st week – lectures about antiproton-proton interactions and heavy-ion collisions, FAIR complex NICA complex, physics applications for PANDA and MPD experiments
2nd – 4rd weeks – physics simulations for exotic states in open charm decays and decays into low lying charmonium states together with light mesons
5th – 6th week – event reconstruction in p̅p interactions and pp collisions for the lightest exotic state X(3872), perspective for study of X(3872) in pA collisions with √s ~ 8 GeV
7th week – final report preparation and results discussion
Required skills
The applicant must have a knowledge in physics of p̅p interactions, pp and heavy-ion collisions together with the methods of detector simulation and data analysis
Acquired skills and experience
The applicant must know the methods of detector simulation and data analysis, and acquire experience in C++ programming within the framework of high energy experiments and elementary particle physics
