Rapidity profiles from 3+1D Glasma simulations with finite longitudinal thickness
We present our progress on simulating the Glasma in the early stages of heavy
ion collisions in a non-boost-invariant setting. Our approach allows us to
describe colliding nuclei with finite longitudinal width by extending the
McLerran-Venugopalan model to include a parameter for the Lorentz-contracted
but finite extent of the nucleus in the beam direction. We determine the
rapidity profile of the Glasma energy density, which shows strong deviations
from the boost invariant result. Both broad and narrow profiles can be produced
by varying the initial conditions. We find reasonable agreement when we compare
the results to rapidity profiles of measured pion multiplicities from RHIC.Comment: 5+1 pages, 2 figures, prepared for Proceedings of the European

Broken boost invariance in the Glasma via finite nuclei thickness
We simulate the creation and evolution of non-boost-invariant Glasma in the
early stages of heavy ion collisions within the color glass condensate
framework. This is accomplished by extending the McLerran-Venugopalan model to
include a parameter for the Lorentz-contracted but finite width of the nucleus
in the beam direction. We determine the rapidity profile of the Glasma energy
density, which shows deviations from the boost-invariant result. Varying the
parameters both broad and narrow profiles can be produced. We compare our
results to experimental data from RHIC and find surprising agreement.Comment: 6 pages, 4 figure
