The Compact X and Z and their Invisible Molecular Partners
A. Carducci, B. Grinstein, D. Germani +1
We propose a model explaining the strong isospin violations observed in X(3872) decays. The X is assumed to be a compact isosinglet tetraquark and its charged partners to form an i…
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…
Towards Low-Energy Electron High-Resolution Spectroscopy with Transition-Edge Sensors
R. Ammendola, A. Apponi, G. Benato +62
We present a study of the energy resolution of transition-edge sensors (TESs) for the detection of electrons in the 100 eV kinetic energy range. The TES is a Ti-Au bilayer with an…
Light scalar mesons in D^+, D_s^+ decays into three pseudoscalars
L. Maiani, A. D. Polosa, V. Riquer
In response to recent experimental findings from the BES III and LHCb collaborations concerning the decay of open charm mesons into three pseudoscalars, we present evidence suggest…
