Dark Energy and QCD Instanton Vacuum in Friedmann–Lemaître–Robertson–Walker Universe

We are pleased to invite you to a seminar by Academician Mirzayusuf Musakhanov from the National University of Uzbekistan.

Abstract / Outline:

This seminar will explore a fascinating intersection of cosmology and quantum field theory. The speaker will discuss:

1. Current models of the universe: ΛCDM vs wφ CDM; the FLRW metric

2. Matter fields in the FLRW universe: Standard Model, Electroweak and QCD sectors, gauge field topology, quantum gluodynamics, and instantons

3. The Instanton Liquid Model of the QCD Vacuum: Excitations, scalar glueball fields, and implications for dark energy in the FLRW context
