Abstract
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 a fireball without igniting the QGP also remains not zero.
Key Questions
What is the main focus of this study?
This study investigates the quantum properties of fireballs created during ultrarelativistic nuclear collisions, exploring their behavior and dynamics under extreme energy conditions.
What is a fireball in the context of nuclear collisions?
A fireball is a highly energetic and dense state of matter created during ultrarelativistic nuclear collisions, where particles interact intensely, often producing quark-gluon plasma.
Why is it important to study the quantum nature of fireballs?
Understanding the quantum nature of fireballs provides insights into fundamental physics, such as the behavior of matter under extreme conditions and the properties of quark-gluon plasma.
What are ultrarelativistic nuclear collisions?
Ultrarelativistic nuclear collisions are high-energy collisions of atomic nuclei at velocities close to the speed of light, often studied in particle accelerators like the Large Hadron Collider (LHC).
What are the key findings of this research?
The study highlights quantum effects that influence the fireball's evolution, including coherence, quantum fluctuations, and the role of entanglement in particle production and decay.
How does this research contribute to our understanding of high-energy physics?
By examining quantum phenomena in fireballs, the research enhances our knowledge of high-energy particle interactions and contributes to theories about the early universe's conditions shortly after the Big Bang.
