Mass splitting and spin alignment for $$\phi $$ ϕ mesons in a magnetic field in NJL model
Abstract Based on the Nambu–Jona–Lasinio (NJL) model, we develop a framework for calculating the spin alignment of vector mesons and applied it to study $$\phi $$ ϕ mesons in a magnetic field. We calculate mass spectra for $$\phi $$ ϕ mesons and observe mass splitting between the longitudinally pola...
