14. How to study matter ?
Properties of matter: Conductivity, color, density, phase states, magnetism,…
Example method: Partonic energy loss, ergo kind of finding a Bethe-Bloch for partons.
Probe: Quarks.
For example energy loss of heavy quarks (c and b) delivers important informations about the Quark-Gluon Plasma.
Measurement: Yields of electrons originating from hadrons and hadrons themselves containing heavy quarks like D0(c, u(bar)), B0(b(bar), u),...
