Angular analysis technique for systems of two identical vector mesons and its applications in the LHCb experiment — •Ilya Segal, Mikhail Mikhasenko, and Marian Stahl — Ruhr-University Bochum, Bochum, Germany
The angular analysis of systems composed of two identical vector mesons offers a powerful framework for probing a wide range of physical phenomena. Notable examples include searches for all-charm tetraquarks Tcccc in the J/ψ J/ψ system, investigations of glueball candidate in the central exclusive production of φ φ, and studies of the internal structure of charmonia through their decays to φ φ. A dedicated technique for constructing reaction amplitudes for the production of resonances decaying into pairs of identical vector particles is presented. The method accounts for the full symmetry properties of the system and provides a consistent framework for amplitude modeling and angular analysis. Applications of this technique to LHCb data are presented.
