论文摘要
在本文中，相对论核碰撞中形成的火球被认为是量子对象。基于此，试图解释两个实验中超子产量的测量值的差异-NA49和NA57。使用量子力学的基本原理，表明火球可以具有两个量子状态 - 带有和没有点火夸克 - 胶状等离子体（QGP）。随着重离子的碰撞能量的增加，QGP点火的可能性增加。同时，即使在核碰撞能量远高于阈值QGP形成能量的核碰撞能量中，没有QGP点火的火球形成的概率也仍然是非零的，这可能被错误地认为是固定的，并且在现代重离子加速器中被强烈寻求。因此，重离子碰撞\ sqrt {s_ {nn}} = 17.3 gev的能量远高于所假定的QGP形成的假定阈值阈值，或略高于\ sqrt {s_ {s_ {nn}}} = 3 gev的一半，只有一半的中央造成的重点，将重点造成的一半。一半的碰撞导致只有harronic物质就形成了火球。
In the article, the fireball formed in the collision of relativistic nuclei is considered as a quantum object. Based on this, an attempt is made to explain the difference in the measurements of hyperon yields in the two experiments - NA49 and NA57. Using the basic principles of quantum mechanics, it was shown that a fireball can have two quantum states - with and without ignited Quark-Gluon Plasma (QGP). With an increase of the collision energy of heavy ions, the probability of QGP ignition increases. At the same time, the probability of the formation of fireball without QGP ignition also remains nonzero even at nuclear collision energies that are much higher than the threshold QGP formation energy, which may be erroneously considered to be fixed and which is intensively sought in modern heavy ion accelerators. Thus, at SPS energy of heavy ion collisions \sqrt{s_{NN}} = 17.3 GeV, which is much higher than the assumed threshold energy of QGP formation in the region around or slightly above of \sqrt{s_{NN}} = 3 GeV, only half of the central collisions of heavy ions bring to the formation of a fireball consisted of deconfined matter, the remaining half of the collisions lead to the formation of a fireball from only hadronic matter.
