Scientific field of the chair is a borderline between theories of
elementary particles, cosmology and astrophysics.
Scientific results obtained by the staff members
include several results which played crucial role in development of
physics and astrophysics of elementary particles and cosmology.
 New quantum number  color  is introduced. This number plays
fundamental role in the theory of strong interactions.
(N.
Bogolyubov, B. Struminsky, A. Tavkhelidze, 1965)
 New rules of elastic hadron scattering at large angles and
high energies are discovered. (
V.A. Matveev, R.M. Muradyan, A.N. Tavkhelidze, 1973)
 It is shown that presence of magnetic monopoles leads to
intensive baryon number violation (monopole catalysis of proton decay).
(V.A. Rubakov, 1982)
 A possibility for explaining the observable baryon asymmetry of
the Universe due to Ist order phase transition is demonstrated.(
V.A. Kuzmin, V.A. Rubakov, M.E. Shaposhnikov, 1985)
 First brane world model with noncompact extra dimension is suggested. (
V.A. Rubakov, M.E. Shaposhnikov, 1983)
 A hypothesis that BL Lacertae are sources of highenergy cosmic rays
is suggested. (
P.G. Tinyakov, I.I. Tkachev, 2001)
