用ALICE探测器在LHC上产生光矢量介子

Light vector meson production at the LHC with the ALICE detector

Elisa Incani

摘要:

pp碰撞中光矢量介子产生(ρ,ω,π)的测量为研究LHC能区的软量子色动力学(QCD)过程提供了新的视角。在这种情况下的计算是基于QCD启发的唯象模型,必须调整到数据。此外,轻矢量介子的产生为高能重离子碰撞提供了参考。利用ALICE实验测量了7 TeV pp碰撞中的π和ω微分截面,以及2.76 TeV pp碰撞中的π截面,测量了它们衰变到μ子对的过程,测量的快度区间为2.5 < y < 4。

英文摘要:

The measurement of light vector meson production (ρ, ω, ϕ) in pp collisions provides insight into soft Quantum Chromodynamics (QCD) processes in the LHC energy range. Calculations in this regime are based on QCD inspired phenomenological models that must be tuned to the data. Moreover, light vector meson production provides a reference for high-energy heavy-ion collisions. A measurement of the ϕand ωdifferential cross sections as performed by the ALICE experiment in pp collisions at 7 TeV and of the ϕcross section in pp collisions at 2.76 TeV through their decay to muon pairs and in the rapidity interval 2.5 < y < 4.
