LHCb的中央独家生产

Central Exclusive Production at LHCb

Ronan McNulty

摘要:

中心独占产生(CEP)是强子机器中的一个独特过程,其中粒子通过无色传播子产生。LHCb测量了光生矢量介子$J/ψ,ψ(2S),Υ(1S),Υ(2S)$和$Υ(3S)$的CEP截面。在双坡密子交换过程中,我们对$χ_{c0},χ_{c1}, χ_{c2}$介子的产生进行了初步的测量,同时对charmonia对$J/ψJ/ψ$和$J/ψψ(2S)$的CEP进行了首次观测,并对其它charmonia对的产生进行了限制。

英文摘要:

Central Exclusive Production (CEP) is a unique process at hadron machines in which particles are produced via colourless propagators. LHCb have measured the cross-sections for the CEP of vector mesons, $J/ψ,ψ(2S),Υ(1S),Υ(2S)$ and $Υ(3S)$, which are photo-produced. In the double pomeron exchange process, preliminary measurements have been made of $χ_{c0},χ_{c1}, χ_{c2}$ meson production while the first observations of the CEP of pairs of charmonia, $J/ψJ/ψ$ and $J/ψψ(2S)$, have been made and limits obtained on the pair production of other charmonia.
