Generalized Wilson-Fisher critical points from the conformal OPE
Ferdinando Gliozzi, Andrea Guerrieri, Anastasios C. Petkou +1
We study possible smooth deformations of Generalized Free Conformal Field Theories in arbitrary dimensions by exploiting the singularity structure of the conformal blocks dictated…
A note on the newly observed Y(4220) resonance
R. Faccini, G. Filaci, A. L. Guerrieri +2
BES III Collaboration has recently observed a vector resonance in the chi_{c0} omega channel, at a mass of about 4220 MeV, named Y(4220). Hints of a similar structure appear in the…
Flavored tetraquark spectroscopy
A. L. Guerrieri, M. Papinutto, A. Pilloni +2
The recent confirmation of the charged charmonium like resonance Z(4430) by the LHCb experiment strongly suggests the existence of QCD multi quarks bound states. Some preliminary r…
Probing the nature of Z_c states via the eta_c rho decay
A. Esposito, A. L. Guerrieri, A. Pilloni
The nature of the so-called XYZ states is a long-standing problem. It has been suggested that such particles may be described as compact four-quark states or loosely bound meson mo…
Production of Tetraquarks at the LHC
A. L. Guerrieri, F. Piccinini, A. Pilloni +1
The high prompt production cross section of X(3872) at hadron colliders has shown to be very informative about the quark nature of the X, Y, Z states. We present here a number of r…
Has the Goldstone theorem been revisited?
A. Guerrieri, A. Pilloni
A recent paper (arXiv:1404.5619) claimed the presence of a loophole in the current-algebra proof of Goldstone Theorem. The enforcing of manifest covariance would lead to contradict…
