P. Danielewicz, et al., Science

Fuchs, et al., PRL 86 (01)

Kaon production in heavy and light collision systems

C. Fuchs, H.H. Wolter, EPJA 30(2006)5

Momentum distribution („flow“) measurements

Determination of EoS in Heavy Ion Collisions

Theoretical models (Skyrme EDF, RMF, (D)BHF, Variational, ChPT,…)

Test in heavy ion collisions (Boltzmann-type transport models, sensitive oservables

 Reasonably tight limits

Hermann Wolter, LMU, Munich; CompStar EoS Workshop, GSI, Darmstadt, July 14, 2010


Determina-tions at low densities

B. Tsang, et al., PRL 102, 122701 (2009)

… and at high density:

elliptic flow

and pion production

W. Trautmann,et al.

PPNP 62 (425)

Z. Xiao et al., PRL 102 (09)

The nuclear symmetry energy

C. Fuchs, H.H. Wolter, EPJA 30(2006)5

B.A.LI, et al.,Phss. Rep. 08

 Large uncertainty!

Hermann Wolter, LMU, Munich; CompStar EoS Workshop, GSI, Darmstadt, July 14, 2010


Present constraints on the high density symmetry energy
