Spectral properties of $\rho$ meson in a magnetic field

Snigdha Ghosh, Arghya Mukherjee, Mahatsab Mandal +2

We calculate the rho meson mass in a weak magnetic field using effective $\rho \pi \pi$ interaction. It is seen that both ${\rho }^0$ and ${\rho }^{\pm }$ masses decrease with the magnetic field in vacuum…
