Jet quenching as a probe of the initial stages in heavy-ion collisions
2019
Jet quenching provides a very flexible variety of observables which are sensitive to different energy- and time-scales of the strongly interacting matter created in heavy-ion collisions. Exploiting this versatility would make jet quenching an excellent chronometer of the yoctosecond structure of the evolution process. Here we show, for the first time, that a combination of jet quenching observables is sensitive to the initial stages of heavy-ion collisions, when the approach to local thermal equilibrium is expected to happen. Specifically, we find that in order to reproduce at the same time the inclusive particle production suppression, $R_{AA}$, and the high-$p_T$ azimuthal asymmetries, $v…
Heavy quark momentum diffusion coefficient in 3D gluon plasma
2020
We study the heavy-quark momentum diffusion coefficient in far from equilibrium gluon plasma in a self-similar regime using real-time lattice techniques. We use 3 methods for the extraction: an unequal time electric field 2-point correlator integrated over the time difference, a spectral reconstruction (SR) method based on the measured equal time electric field correlator and a kinetic theory (KT) formula. The time-evolution of the momentum diffusion coefficient extracted using all methods is consistent with an approximate $t^{\frac{-1}{2}}$ power law. We also study the extracted diffusion coefficient as a function of the upper limit of the time integration and observe that including the in…
Initial-Stage Suicide Bereavement Experiences: A Case Study.
2022
This study aimed to shed light on the initial-stage bereavement experiences of an individual bereaved by suicide, at three months from the loss of his spouse to suicide. A semi-structured in-depth interview was conducted with the individual, a man in his thirties. The data were analyzed using qualitative assimilation analysis, based on the Assimilation Model and the Assimilation of Problematic Experiences Scale (APES). The APES ratings of the interview revealed that the individual’s bereavement was associated with the earlier stages of APES (all scoring under 3.5). In addition, the swift and frequent fluctuations in the APES ratings gave indications that the bereavement was unstable and co…
