  We consider a probe stable meson in the holographic quark-gluon plasma at
zero temperature and chemical potential. Due to the energy injection into the
plasma, the temperature and chemical potential are increased to arbitrary
finite values and the meson is also excited. Excitation time tex is the time at
which the meson falls into the final excited state. We study the effect of
various parameters of theory on the excitation time and observe that for larger
values of final temperature and chemical potential the excitation time
increases. Furthermore, our outcomes show that the more stable mesons are
excited sooner.
