英文摘要: Low-mass vector meson (rho, omega, and phi) production at forward rapidity in p+p and d+Au collisions at root s(NN) = 200 GeV is studied within the framework of a multiphase transport model (AMPT). Detailed investigations, including the transverse momentum and the rapidity dependence of low-mass vector meson production in the AMPT model, show that the hadron interaction process is important for a quantitative description of the rho and omega data. But for the phi meson, the strange quark production in the AMPT model with the string melting scenario describes the data reasonably well, while the default AMPT model under-predicts the data. The N(phi)/N(rho + omega) ratio from the AMPT model with the string melting scenario perfectly describes the data in p+p collisions. For the d+Au collisions, an increased trend of this ratio vs. transverse momentum and the number of participants are observed from the AMPT model. Our results indicate that a precise measurement of the N(phi)/N(rho + omega) ratio in d+Au and Au+Au collisions will shed more light on the strangeness production and its dynamics in quark-gluon plasma.
