Abstract

The production of gif.latex?K^{-}pp and gif.latex?K^{+}\bar{p}\bar{p}  are predicted by using the Dynamically Constrained Phase space Coalescence (DCPC) model with based on the final staes of the hadron (gif.latex?K^{\pm&space;},gif.latex?p , gif.latex?\bar{p} ) from PACIAE model at scaled mid-rapidity | y | < 1 and the transverse momentum (gif.latex?p_{T}) range of 0.1 - 1.7 GeV/c in proton-proton collisions at gif.latex?\sqrt{s} = 13 TeV. The results of charge particle gif.latex?K^{\pm&space;} , gif.latex?pand gif.latex?\bar{p}  are consistent with CMS experimental data. The result of simulation presented that the yield of the gif.latex?K^{-}pp  is about gif.latex?8.76\times&space;10^{-4} and bigger than their anti (gif.latex?K^{+}\bar{p}\bar{p}) according to the hypothesis that these exotic nuclei clusters are constructed in the way that (anti-)kaon directly traps two (anti-)protons, without going through process of the gif.latex?\Lambda&space;^{*}p doorway state.
