8. Inclusive production of prompt charged particles in pp collisions at LHCb

An analysis of the double-differential cross-section in pseudorapidity and transverse momentum of charged particles in unbiased proton-proton collisions at 13 TeV measured with the LHCb experiment, is presented. This analysis complements previous LHCb measurements at 7 TeV. Noteworthy aspects of our result are the forward pseudorapidity coverage from 2 to 4.8 and the unbiased trigger...

29. Exclusive production of f1(1285) meson at low and high energies

We present a new study of the exclusive production of $f_{1}(1285)$ meson at near threshold energies relevant for the HADES and PANDA experiments at GSI-FAIR [1]. At energies close to the threshold the $VV \to f_{1}(1285)$ fusion processes ($V = \rho, \omega$) are the dominant production mechanisms. The vertex for the $VV \to f_{1}$ coupling is derived from an effective coupling Lagrangian. In...

39. Exotic mesons and final state interactions in electron-positron collisions

In my talk I will present the dispersive formalism we developed to analyse the BESIII data for the processes $ e^+ e^- \to \psi (2S) \, \pi \, \pi$ and $ e^+ e^- \to J/\psi \, \pi \, \pi$. We use the powerful dispersion theory, which combines fundamental physical principles such as causality, conservation of probability and crossing symmetry. Furthermore, we test the hypothesis whether exotic...
