Multiplicities and spectra in ultrarelativistic heavy ion collisions from a next-to-leading order improved perturbative QCD + saturation + hydrodynamics model
R. Paatelainen, K. J. Eskola, H. Holopainen +1
We bring the EKRT framework, which combines perturbative QCD (pQCD) minijet production with gluon saturation and hydrodynamics, to next-to-leading order (NLO) in pQCD as rigorously…
Influence of initial state fluctuations on the production of thermal photons
Rupa Chatterjee, Hannu Holopainen, Thorsten Renk +1
Inhomogeneities in the initial QCD matter density distribution increase the production of thermal photons significantly compared to a smooth initial-state-averaged profile in the r…
Dynamical freeze-out in event-by-event hydrodynamics
Hannu Holopainen, Pasi Huovinen
In hydrodynamical modeling of the ultrarelativistic heavy-ion collisions the freeze-out is typically performed at a constant temperature or density. In this work we apply a dynamic…
Centrality and initial formation time dependence of the emission of thermal photons from fluctuating initial conditions at RHIC and LHC
Rupa Chatterjee, Hannu Holopainen, Thorsten Renk +1
Event-by-event fluctuating initial conditions (IC) in the ideal hydrodynamic calculation are known to enhance the production of thermal photons significantly compared to a smooth i…
Initial state anisotropies in ultrarelativistic heavy-ion collisions from the Monte Carlo Glauber model
M. Alvioli, H. Holopainen, K. J. Eskola +1
In hydrodynamicalmodeling of heavy-ion collisions the initial state spatial anisotropies translate into momentum anisotropies of the final state particle distributions. Thus, under…
Collision centrality and dependence of the emission of thermal photons from fluctuating initial state in ideal hydrodynamic calculation
Rupa Chatterjee, Hannu Holopainen, Thorsten Renk +1
Fluctuations in the initial QCD matter density distribution are found to enhance the production of thermal photons significantly in the range 2 \leq pT \leq 4 GeV/c compared to a s…
