摘要:

我们研究了在3.5 GeV动能束流能量下p+p反应中Sigma^+-pi^+-pK^+粒子四重态的产生。这些数据是在GSI的HADES实验中获得的。这份报告评估了共振态如λ(1405$,Sigma(1385)^0,λ(1520),Delta(1232),N^* 和K^*0对Sigma^+- pi^-+ p K+终态的贡献。所得的模拟模型进行比较,在几个角分布的实验数据,它表明自己是合适的,以适当地评估验收修正。

英文摘要:

We study the production of Sigma^+-pi^+-pK^+ particle quartets in p+p reactions at 3.5 GeV kinetic beam energy. The data were taken with the HADES experiment at GSI. This report evaluates the contribution of resonances like Lambda(1405$, Sigma(1385)^0, Lambda(1520), Delta(1232), N^* and K^*0 to the Sigma^+- pi^-+ p K+ final state. The resulting simulation model is compared to the experimental data in several angular distributions and it shows itself as suitable to evaluate the acceptance corrections properly.
