Holographic estimation of multiplicity and membranes collision in modified spaces ${AdS}_5$

Understand

The quark-gluon plasma formed as a result of heavy-ion collisions is currently investigated actively both theoretically and experimentally.

• According to the holographic approach, forming a quark-gluon plasma in the four-dimensional world is associated with creating black holes in a five-dimensional anti-de Sitter space.
• The multiplicity of particles produced in heavy-ion collisions is then determined by the entropy of the five-dimensional black hole, which is estimated by the area of the trapped surface.
• To fit the experimental data for multiplicity Kiritsis and Taliotis have proposed to consider black holes formation in modified ${AdS}_5$ spaces with different $b$-factors.
