Four-Quark Hadrons: an Updated Review

Angelo Esposito, Andrea L. Guerrieri, Fulvio Piccinini +2

The past decade witnessed a remarkable proliferation of exotic charmonium-like resonances discovered at accelerators. In particular, the recently observed charged states are clearl…

Evidence for x-dependent proton color fluctuations in pA collisions at the LHC

Massimiliano Alvioli, Brian Cole, Leonid Frankfurt +2

We argue that the pattern of the deviation from the Glauber approximation prediction for the centrality dependence of the rate of forward jet production observed in pA collisions a…

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…

Initial-State Bremsstrahlung versus Final-State Hydrodynamic Sources of Azimuthal Harmonics in p+A at RHIC and LHC

Miklos Gyulassy, Peter Levai, Ivan Vitev +1

Recent pT<2~GeV azimuthal correlation data from the Beam Energy Scan (BES) and D+Au runs at RHIC/BNL and, especially, the surprising similarity of azimuthal ``tran…

Non-Abelian Bremsstrahlung and Azimuthal Asymmetries in High Energy p+A Reactions

M. Gyulassy, P. Levai, I. Vitev +1

We apply the GLV reaction operator solution to the Vitev-Gunion-Bertsch (VGB) boundary conditions to compute the all-order in nuclear opacity non-abelian gluon bremsstrahlung of ev…

On parton number fluctuations at various stages of the rapidity evolution

A. H. Mueller, S. Munier

Starting with the interpretation of parton evolution with rapidity as a branching-diffusion process, we describe the different kinds of fluctuations of the density of partons which…

The Boltzmann Equation in Classical Yang-Mills Theory

V. Mathieu, A. H. Mueller, D. N. Triantafyllopoulos

We give a detailed derivation of the Boltzmann equation, and in particular its collision integral, in classical field theory. We first carry this out in a scalar theory with both c…
