Physics of strong interactions at high energies

In 2024, we celebrate the 90th anniversary of the Lebedev Physical Institute of the USSR/Russian Academy of Sciences (LPI). One of the most important domains of scientific research at the LPI has been theoretical physics, undertaken in different areas, in the Theoretical Physics Department. In the present review, ideas on the physics of strong interactions developed at the Sector/Laboratory of High Energy Physics in the Theoretical Physics Department are discussed.
