在LHC上研究关联强子间的强相互作用

Study of the strong interaction among hadrons with correlations at the LHC

L. Fabbietti, V. Mantovani Sarti, O. Vazquez Doce

摘要:

强子间的强相互作用过去一直是用散射实验测量的。虽然这种技术在提供核子-核子和π-核子相互作用的信息方面非常成功,但当考虑不稳定强子时,实验变得更具挑战性。近年来,ALICE合作组在LHC上对pp和p-Pb碰撞中测量的稳定和不稳定强子对的动量空间关联分析,为研究强子间的强相互作用提供了一种新的方法。本文回顾了最近在超子-核子、超子-超子和K介子-核子对中所取得的大量结果,这些结果表明这种新方法为测量任意强子对的剩余强相互作用提供了可能性。

英文摘要:

The strong interaction among hadrons has been measured in the past by scattering experiments. Although this technique has been extremely successful in providing information about the nucleon-nucleon and pion-nucleon interactions, when unstable hadrons are considered the experiments become more challenging. In the last few years, the analysis of correlations in the momentum space for pairs of stable and unstable hadrons measured in pp and p-Pb collisions by the ALICE Collaboration at the LHC has provided a new method to investigate the strong interaction among hadrons. In this article, we review the numerous results recently achieved for hyperon-nucleon, hyperon-hyperon, and kaon-nucleon pairs, which show that this new method opens the possibility of measuring the residual strong interaction of any hadron pair.
