Abstract

We present estimates for the production cross sections of charmed states (\(\Lambda _c, \Sigma _c, \Xi _c, D\, \textrm{and}\, D_s\)) from secondary \(\overline{B} + B\) annihilations in p+A reactions from \(E_\textrm{lab}=10-30A\) GeV. We focus specifically on the newly planned hadron physics program of CBM at FAIR. These estimates for the production of charmed states are based on the achievable number of \(\overline{B} + B\) annihilations and their invariant mass distributions calculated in the UrQMD transport model.

FAIR中p+A反应中次级\(\overline{p} + p\)湮灭产生的粲强子

我们给出了\(E_\textrm{lab}=10-30A\) GeV中p+A二次\(\overline{B} + B\)湮灭产生的粲态（\(\Lambda _c, \Sigma _c, \Xi _c, D\, \textrm{and}\, D_s\)）横截面的估计。我们特别关注FAIR新计划的CBM强子物理项目。这些对粲态产生的估计是基于在UrQMD输运模型中计算的\(\overline{B} + B\)湮灭的可实现数量和它们的不变质量分布。
