标题： Resonance lifetime in Boltzmann-Uehling-Uhlenbeck theory: observable consequences

摘要： 在传输BUU理论中，我们研究了选择$\Delta$共振寿命对1 A GeV下介子-核反应和重离子碰撞的影响。如果一致地修改$\Delta$共振的吸收概率，则发现这些修改对介子在核上的吸收影响很小。展示了重离子碰撞情况下的可观测效应。 显示英文摘要

摘要： Within the transport BUU theory we study the influence of the choice for the $\Delta$ resonance lifetime on pion-nucleus reactions and on heavy-ion collisions at 1 A GeV. A quite small effect of these modifications on the pion absorption on nuclei is found provided that the absorption probability of the $\Delta$ resonance is modified consistently. Observable effects in the case of heavy-ion collisions are demonstrated.
