Isosinglet-isotriplet mixing and the $X (3872)$ lineshape

Davide Germani, Benjamin Grinstein

We investigate the lineshapes of the $X (3872)$ in $B^{+}$ decays production within a framework that incorporates two underlying QCD configurations: a compact isosinglet state $X_{S}$ a…

Positivity of the effective range for finite range attractive potentials with a repulsive core

Davide Germani

In the phenomenological study of exotic hadrons, the sign of the effective range, $r_{0}$ , is invoked as a criterion to distinguish between compact multiquark configurations (associa…

A New Look at the X Compositeness from its Lineshape

A. Carducci, G. Cianti, P. D'Annibali +2

Available data on the $X (3872)$ lineshape have been fitted with a Flattè parametrization derived from an effective Lagrangian in which $X$ , $D$ , and $D^{*}$ are all elementary fields…
