Abstract:
Understanding strong interaction is an essential challenge in particle physics. In recent years, researchers have discovered various exotic hadrons, such as pentaquarks, tetraquarks, and others. These particles need to be classified and better understood. In this seminar, we will explore techniques for analyzing hadron resonances, with a special focus on three-body problems, which present challenges across various fields of particle physics.
We will discuss recent studies on hadronic three-body amplitudes and their application in characterizing new types of particles, like doubly charmed tetraquarks. I will show how our growing understanding of three-body physics enhances the study of charm baryons and opens new avenues in Beyond the Standard Model searches using the polarimetry vector field. We will also explore how this knowledge might help resolve challenges in interpreting hadron correlation functions, connecting lattice QCD and experimental studies of hadron interactions through the femtoscopy technique.
I will also touch upon machine learning methods, and advances in computational techniques, like differentiable programming, that help with these analyses.
