Abstract:By extending the Φ-derivable approach in Nambu-Jona-Lasinio model to finite magnetic field we calculate the properties of pion, σ and ρ mesons in a magnetic field at finite temperature in not only the quark-antiquark bound state scheme but also the pion-pion scattering resonant state scenario. Our calculation results manifest that the masses of π0 and σ meson can be nearly degenerate at the pseudo-critical temperature which increases with increasing the magnetic field strength, and the π± mass ascends suddenly at almost the same critical temperature. While the ρ mesons' masses decrease with th
