The Modified Camassa--Holm Equation with Step-Like Boundary Conditions: A Characterization of Existence
I. Karpenko, D. Shepelsky, G. Teschl
We consider the Cauchy problem for the modified Camassa-Holm equation \[ u_t+\left((u^2-u_x^2)m\right)_x=0,\quad m:= u-u_{xx}, \quad t>0,\ \ -\infty<x<+\infty \] subject to the ste…

SUBA-Jet: a new Model for Jets in Heavy Ion Collisions
Iurii Karpenko, Alexander Lind, Martin Rohrmoser +2
We present a new model for jet quenching in a quark gluon plasma (QGP). The jet energy loss has two steps. The initial jet parton with a high virtuality loses energy by a perturbat…

Heavy ion collisions from of 62.4 GeV down to 4 GeV in the EPOS4 framework
K. Werner, J. Jahan, I. Karpenko +3
The EPOS4 project is an attempt to construct a realistic model for describing relativistic collisions of different systems, from proton-proton () to nucleus-nucleus (), at…
