An aspect of high-energy nuclear collision that has been under vigorous debate recently concerns the quenching of jets by the expanding hot and dense medium. Experimental data show an anomalous behaviour in the angular distribution of the particles created in the jet [1].
However, it is not entirely clear how the jet interacts with the medium and therefore we study a scenario within an ideal (3+1)d hydrodynamics approach [2] in which the jet deposits all of its energy and momentum during a very short time in a small spatial volume.
Clearly, the medium will strongly depend on the underlying equation of state and therefore will influcence the evolution of the jet through the medium.
