20.500.12556/RUL-135168 Lastnosti magnetnega polja v kvark-gluonski plazmi pri trkih težkih ionov Properties of magnetic field in quark-gluon plasma in heavy ion collisions V hadronskih trkalnikih, kot je Veliki hadronski trkalnik v Cernu, lahko v zadnjih dveh desetletjih s trki težkih ionov poustvarijo plazmo elementarnih delcev, imenovano kvark-gluonska plazma, ki jo je vsebovalo vesolje le nekaj milijonink sekunde po velikem poku. Pri necentralnem trku ionov se v središču plazme ustvari izjemno močno magnetno polje, ki je pravokotno na ravnino trka kvark-gluonske plazme. Prav tako je možno, da se po trku v plazmi zaradi kiralnega magnetnega efekta inducira magnetno polje tudi v drugih smereh. S pomočjo magnetohidrodinamike, ki preučuje obnašanje električno prevodne tekočine v magnetnem polju, bomo izračunali velikost magnetnega polja v različnih smereh, kako hitro to magnetno polje razpada in kako dolgo obstane v tej plazmi. Na koncu je prikazano tudi, kako je to magnetno polje odvisno od električne prevodnosti in kiralne magnetne prevodnosti. In hadron colliders, such as at the Large Hadron Collider in CERN, heavy-ion collision experiments have over the past two decades been able to create a plasma of elementary particles called the quark-gluon plasma. This type of plasma filled the universe just a few millionths of a second after the big bang. In an off-central heavy-ion collision, an extremely strong magnetic field is created in the center of the plasma. This strong magnetic field is initially perpendicular to the plane of the quark-gluon plasma collision. However, due to the chiral magnetic effect, it is possible that after the collision, magnetic field is also induced in other directions. Using magnetohydrodynamics, which is a theory that studies the behavior of an electrically conductive fluid in a magnetic field, we calculate the magnitude of the magnetic field in different directions, estimate how quickly the field decays, and thereby understand how long appreciable magnetic fields persist in the plasma. Moreover, we also show how this magnetic field depends on the electrical conductivity and the chiral magnetic conductivity.
