In high-energy nuclear collisions at LHC, where a QGP might be created, the degree of thermalization at the partonic level is a key issue. Due to their large mass, heavy quarks are a powerful tool to probe thermalization. We propose to measure azimuthal correlations of heavy-quark hadrons and their decay products. Changes or even the complete absence of these initially existing azimuthal correlations in $Pb-Pb$ collisions might indicate thermalization at the partonic level. We present studies with PYTHIA for $p-p$ collisions at 14 TeV using the two-particle transverse momentum correlator ${<overline{Delta}p_{t,1}overline{Delta}p_{t,2}>}$ as a sensitive measure of potential changes in these azimuthal correlations. Contributions from transverse radial flow are estimated.

tion. We propose measuring azimuthal correlations of heavy-quark hadrons and products from their semi-leptonic decay. Modifications or even the complete absence of initially, e.g. in p-p collisions, existing azimuthal correlations in Pb-Pb collisions might indicate thermalization at the partonic level. We present studies with PYTHIA for p-p collisions at the top LHC energy using the two-particle transverse momentum correlator ${<overline{Delta}p_{t,1}overline{Delta}p_{t,2}>}$ as a sensitive measure of azimuthal correlations.

alization. We present studies with PYTHIA for p+p collisions at the top LHC energy of $sqrt{s}$ = 14 TeV applying the two-particle transverse momentum correlator $<Delta p_{t,1}, Delta p_{t,2}>$ to pairs of heavy-quark hadrons and their semi-leptonic decay products as a function of their relative azimuth. Modifications or even the complete absence of initially existing correlations in Pb+Pb collisions might indicate thermalization at the partonic level.
We propose to measure azimuthal correlations of heavy-flavor hadrons to address the status of thermalization at the partonic stage of light quarks and gluons in high-energy nuclear collisions. In particular, we show that hadronic interactions at the
late stage cannot significantly disturb the initial back-to-back azimuthal correlations of DDbar pairs. Thus, a decrease or the complete absence of these initial correlations does indicate frequent interactions of heavy-flavor quarks and also light partons in the partonic stage, which are essential for the early thermalization of light partons.
The production and propagation of kaons and antikaons has been studied in symmetric nucleus-nucleus collisions in the SIS energy range. The ratio of the excitation functions of K^+ production in Au+Au and C+C collisions increases with decreasing beam
energy. This effect was predicted for a soft nuclear equation-of-state. In noncentral Au+Au collisions, the K^+ mesons are preferentially emitted perpendicular to the reaction plane. The K^-/K^+ ratio from A+A collisions at beam energies which are equivalent with respect to the threshold is found to be about two orders of magnitude larger than the corresponding ratio from proton-proton collisions. Both effects are considered to be experimental signatures for a modification of kaon properties in the dense nuclear medium.
When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that a more general and relevant question is when does a system thermalize
relative to a particular reference? By relative thermalization we mean that, as well as being in a local thermal state, the system is uncorrelated with the reference. We argue that this is necessary in order to apply standard statistical mechanics to the study of the interaction between a thermalized system and a reference. We then derive a condition for relative thermalization of quantum systems interacting with an arbitrary environment. This condition has two components: the first is state-independent, reflecting the structure of invariant subspaces, like energy shells, and the relative sizes of system and environment; the second depends on the initial correlations between reference, system and environment, measured in terms of conditional entropies. Intuitively, a small system interacting with a large environment is likely to thermalize relative to a reference, but only if, initially, the reference was not highly correlated with the system and environment. Our statement makes this intuition precise, and we show that in many natural settings this thermalization condition is approximately tight. Established results on thermalization, which usually ignore the reference, follow as special cases of our statements.
