Abstract:
We compute bremsstrahlung arising from the
acceleration of
individual charged baryons and mesons during
the time
evolution of high-energy Au+Au collisions at the
Relativistic Heavy Ion Collider using a
microscopic
transport model. We elucidate the connection
between
bremsstrahlung and charge stopping by
colliding artificial
pure proton on pure neutron nuclei. From the
intensity of
low energy bremsstrahlung, the time scale and
the degree of
stopping could be accurately extracted
without measuring any
hadronic observables.
