Determining Critical Exponents?

• EOS-TPC: Complete reconstruction of all charges

• Assume charged-particle multiplicity is proportional to control parameter

Gilkes et al.,

PRL 73, 1590 (1994)

• Find critical value, mc, and extract critical exponents b and g: g = 1.4, b = 0.29

• Assuming validity of hyper-scaling: universality class of transition is completely determined
