39. Quarkonium production in proton-nucleus collisions at collider energies

Heavy quark pair production in high energy proton-nucleus (pA) collisions provides valuable information of the gluon saturation dynamics in a heavy nucleus at small value of Bjorken x. Nowadays, large amounts of data accumulated by RHIC and LHC enable us to examine calculations in small-x saturation formalism or Color Glass Condensate (CGC). Essentially, heavy quark pair production has been...

23. Diffractive vector meson production and initial state fluctuations in DIS

Dr Heikki Mäntysaari (Brookhaven National Laboratory)

Exclusive vector meson production can be used to directly probe the gluon density of a hadron. Measuring the cross section differentially in transverse momentum transfer makes it possible to determine the transverse density profile (via coherent diffraction) and density fluctuations (incoherent diffraction) of the target hadron. This knowledge about the geometric fluctuations of the proton is...

1. Polarized Heavy Quarkonia Production in the Color Evaporation Model

Mr Vincent Cheung (University of California, Davis)

2/2/17, 11:50 AM

Even more than 40 years after the discovery of $J/\psi$, the production mechanism of quarkonia is still not well understood. Non-Relativistic Quantum Chromodynamics (NRQCD), perhaps the best known approach for studying quarkonia production can reproduce the $J/\psi$ $p_T$ distribution. However, the long distance matrix elements (LDMEs) fitted from the $p_T$ distributions fail to...
