We show a theorem proving that a non-local bosonic field upon a covariant interaction with a confining gauge field undergoes the confinement of its degrees of freedom present in the free theory changing completely the physical mass spectrum. This is applicable to an infinite number of excitations of the bosonic field including ghosts whereas we pay special attention the the modes with the complex conjugate masses – mysterious states appearing in the string field theory motivated infinite-derivative…

Generalized non-local $R^2$-like inflation

: The R 2 inflation which is an extension of general relativity (GR) by quadratic scalar curvature introduces a quasi-de Sitter expansion of the early Universe governed by Ricci scalar being an
