    "abstract": "A survey of various mechanisms for particle emission in hydrodynamics is\npresented. First, in the case of sudden freeze out, the problem of negative\ncontributions in the Cooper-Frye formula and ways out are presented. Then the\nseparate chemical and thermal freeze out scenario is described and the\nnecessity of its inclusion in a hydrodynamical code is discussed. Finally, we\nshow how to formulate continuous particle emission in hydrodynamics and discuss\nextensively its consistency with data. We point out in various cases that the\ninterpretation of data is quite influenced by the choice of the particle\nemission mechanism.",
