### Description

We analyze the yield of charged particles (${K^ + },{K^ - },p$ and ${\bar p}$) in $pp$ collisions at 7 TeV by using the PACIAE model and comparing with experimental data from ALICE. The prediction of ${K^ - }p$ and ${K^ + }\bar p$ bound states in $pp$ collisions at 7 TeV is calculated by using PACIAE+DCPC model. Using a realistic invariant mass of 1.405 GeV, we are predict the yields per event of ${K^ - }p$ and ${K^ + }\bar p$ bound states to be $3.530 \times {10^{ - 3}}$ and $3.270 \times {10^{ - 3}}$, respectively. The $\Lambda \left( {1405} \right)$ and it antiparticle may be produced at almost the same rate in $pp$ collisions at 7 TeV if the $\Lambda \left( {1405} \right)$ is a ${K^ - }p$ bound state. The total yield of ${K^ - }p$ and ${K^ + }\bar p$ is to be $6.80 \times {10^{ - 3}}$. There are no experimental data available for the yield of ${K^ - }p$ and ${K^ + }\bar p$. This research may provide a guide to future experiments.
