We evaluate the bremsstrahlung production of low mass dileptons and softphotons from equilibrating and transversely expanding quark gluon plasma whichmay be created in the wake of relativistic heavy ion collisions. We use initialconditions obtained from the self screened parton cascade model. We consider aboost invariant longitudinal and cylindrically symmetric transverse expansionof the parton plasma and find that for low mass dileptons ($M \leq 0.3$ GeV)and soft photons ($p_{T} \leq 0.5$ GeV), the bremsstrahlung contribution israther large compared to annihilation process at both RHIC and LHC energies. Wealso find an increase by a factor of 15-20 in the low mass dileptons and softphotons yield as one goes from RHIC to LHC energies.Comment: 8 pages, including 7 figures To appear in Phys. Rev.
