A New Look at the X Compositeness from its Lineshape
A. Carducci, G. Cianti, P. D'Annibali +2
The existing analyses on the X(3872) lineshape are consistent with the hypothesis that it is a compact particle composed of four quarks. This conclusion follows from fitting availa…

Study of the scalar and pseudoscalar meson mass spectrum above the QCD chiral phase transition, using an effective Lagrangian approach
Giulio Cianti, Enrico Meggiolaro
In this work, expanding on previous analyses, we employ an effective Lagrangian approach to investigate the mass spectrum of scalar and pseudoscalar mesons at finite temperature, a…
