在LHC的相干强子相互作用中的大$t$衍射矢量介子产生

Diffractive vector meson production at large-$t$ in coherent hadronic interactions at CERN LHC

V. P. Goncalves, W. K. Sauter

摘要:

假设色单重态$t$通道交换携带大动量转移,研究了LHC能区强子-强子相干相互作用中强子解离的衍射矢量介子光生.考虑高能大动量转移下BFKL方程的非正解,我们估计了过程$pp \rightarrow p V X$和$PbPb \rightarrow Pb V X$($V = ρ$或$Υ$)的快度分布和总截面.我们的结果表明,这些过程的实验识别在LHC是可行的。

英文摘要:

The diffractive vector meson photoproduction with hadron dissociation in coherent hadron-hadron interactions at LHC energies is studied assuming that the color singlet $t$-channel exchange carries large momentum transfer. We estimate the rapidity distribution and total cross section for the processes $pp \rightarrow p V X$ and $PbPb \rightarrow Pb V X$ ($V = ρ$ or $Υ$) considering the non-forward solution of the BFKL equation at high energy and large momentum transfer. Our results indicate that the experimental identification of these processes can be feasible at the LHC.
