Evolution of Quarkonia States in a Rapidly Varying Strong Magnetic Field

In a transient magnetic field, heavy quarkonium bound states evolve non-adiabatically. In the presence of a strong magnetic field, \(J/\Psi \) and \(\varUpsilon (1S)\) become more tightly bound than we expected earlier for a pure thermal medium. We have shown that in a time- varying magnetic field, there is a possibility of moderate suppression of \(J/\Psi \) through the non-adiabatic transition to continuum whereas the \(\varUpsilon (1S)\) is so tightly bound that it cannot be dissociated through this process. We have calculated the dissociation probabilities up to the first order in the time-dependent perturbation theory for different values of initial magnetic field intensity.
