The Roper resonance: a genuine quark state or a dynamically generated structure?
B. Golli, H. Osmanović, S. Širca +1
In view of the recent results of lattice QCD simulation in the P11 partial wave that has found no clear signal for the three-quark Roper state we investigate a different mechanism…
Fundamental properties of resonances
S. Ceci, M. Hadžimehmedović, H. Osmanović +2
All resonances, from hydrogen nuclei excited by the high-energy gamma rays in deep space to newly discovered particles produced in Large Hadron Collider, should be described by the…
Introducing Pietarinen expansion method into single-channel pole extraction problem
Alfred Svarc, Mirza Hadzimehmedovic, Hedim Osmanovic +3
We present a new approach to quantifying pole parameters of single-channel processes based on a Laurent expansion of partial-wave T-matrices in the vicinity of the real axis. Inste…
Stability of the Zagreb Carnegie-Mellon-Berkeley model
H. Osmanović, S. Ceci, A. Švarc +2
In ref. [1] we have used the Zagreb realization of Carnegie-Melon-Berkeley coupled-channel, unitary model as a tool for extracting pole positions from the world collection of parti…
