Description
We present a systematic study of electromagnetic radiation and of the hadronic observables in (p, d, $^3$He)+Au collisions at RHIC energies and in p+Pb collisions at the LHC energy. Using a (3+1)-d viscous hydrodynamics + hadronic cascade hybrid framework, the effects of breaking the longitudinal boost-invariance on direct photon and hadronic observables are quantified. Predictions of thermal photon enhancement in high multiplicity pp collisions at 13 TeV and in the recent beam energy scan (d+Au collisions at RHIC energies) will be presented. The role of net baryon density and finite baryon diffusion on direct photon and flow observables will be highlighted for d+Au collisions at 19.6 GeV. The proposed thermal photon enhancement [1] and flow observables at low collision energies can serve as additional signatures for the existence of a hot quark-gluon plasma in small collision systems.
