Abstract:
The spectroscopy of exotic hadrons is a promising way to reveal how non-perturbative QCD works. Since discovery of the first exotic hadron, X(3872), in 2003 more than 50 exotic hadron candidates reported. However, the true nature of these exotic states remains a mystery. In order to unravel this mystery, it is necessary to study specific hadrons, where experimental measurements and theoretical interpretation are especially clear and unambiguous. In this seminar we will discuss how the Tcc tetraquark discovered in 2021 marks the path for advanced understanding of exotic hadrons. We will then discuss what states, yet to be discovered, will give even better prospects for this, and how they can be searched by the LHCb experiment now and after the Upgrade II.
About the speaker:
Dr. Ivan Polyakov graduated from ITEP (Moscow, Russia) in 2015. He became a postdoc at Syracuse University, USA from 2016 to 2021, and then he became a senior research fellow at CERN from 2022 until now. Dr. Ivan Polyakov works in the field of hadron spectroscopy, including studying the radiative decays of the χ_c1 (3872) and discovering the double-charmed tetraquark T_cc at LHCb. He also contributed to R&D and the module construction of the Upstream Tracker (UT) for the LHCb Upgrade I. Most recently, he has been involved in R&D for the TORCH detector aimed at the LHCb Upgrade II.
