We present Monte Carlo simulations of the Sivers effect in the polarized Drell-Yan pp(up arrow)->mu(+)mu X- process at the center-of-mass energy root s=200 GeV reachable at the Relativistic Heavy-Ion Collider (RHIC) of BNL. We use two different parametrizations for the Sivers function, one deduced from the analysis of semi-inclusive deep-inelastic scattering (SIDIS) data at much lower energies, and another one constrained by the RHIC data for the pp(up arrow)->pi X process at the same energy. For a given luminosity of 10(32) cm(-2) s(-1), we explore the necessary conditions to reach a statistical accuracy that allows one to extract unambiguous information on the structure of the Sivers function. In particular, we consider the feasibility of the test on its predicted universality property of changing sign when switching from SIDIS to Drell-Yan processes.

Abstract
We present Monte Carlo simulations of the Sivers effect in the polarized Drell-Yan pp(up arrow)->mu(+)mu X- process at the center-of-mass energy root s=200 GeV reachable at the Relativistic Heavy-Ion Collider (RHIC) of BNL. We use two different parametrizations for the Sivers function, one deduced from the analysis of semi-inclusive deep-inelastic scattering (SIDIS) data at much lower energies, and another one constrained by the RHIC data for the pp(up arrow)->pi X process at the same energy. For a given luminosity of 10(32) cm(-2) s(-1), we explore the necessary conditions to reach a statistical accuracy that allows one to extract unambiguous information on the structure of the Sivers function. In particular, we consider the feasibility of the test on its predicted universality property of changing sign when switching from SIDIS to Drell-Yan processes.File | Dimensione | Formato | |
