Studies of the Roper Resonance by the Ljubljana Group
Ever since its discovery in 1964, the nature of the \(N^\ast (1440)\) nucleon resonance has been a perpetual and one of the outstanding puzzles in hadronic physics. The Ljubljana group joined the global effort in the late 1990s, first from the theoretical viewpoint and later experimentally. This paper is a short overview of our attempts to understand this elusive resonance. Abstract Published by the Jagiellonian University 2026 authors
