Particle azimuthal anisotropies inside jets, defined within the momentum plane perpendicular to the jet axis, carry the information of the QCD cascade process for jet formation. In this work, we propose to measure the medium-induced modifications of the elliptic anisotropy inside jets in relativistic heavy-ion collisions to provide novel insight into the jet quenching phenomenon. By simulating...
探究 J/ψ和 Υ(1S)这类重矢量介子对于理解重离子碰撞中形成的夸克胶子等离子体(QGP)至关重要。本研究通过在全息QCD中引入旋转介质,考察了旋转效应对 J/ψ和 Υ(1S)性质的影响。研究发现,温度、化学势以及旋转半径效应会促进 J/ψ和 Υ(1S)态在介质中的解离过程。这种旋转诱导的效应对于横向的重矢量介子比纵向更为显著。本文首次在全息框架下研究了均匀旋转系统半径对矢量介子谱的影响,发现旋转半径的增大会促进 J/ψ和 Υ(1S)的解离。我们还发现,在较大旋转半径下,垂直于旋转角速度方向的解离比平行方向的解离更为显著。
Shear and bulk viscosities are two key transport coefficients that characterize the fundamental properties of quark-gluon plasma.They quantify the response of the energy-momentum tensor to shear flow and divergent flow,serving as crucial input parameters for the phenomenological and transport models that interpret experimental data, such as the elliptic flow $v_2$.
However, calculating...
In this work, a simulation and analysyis framework for the N$\nu$DEx experiment is presented.
N$\nu$DEx aims to search for the neutrinoless double beta decay in $^{82}$Se using a high pressure $^{82}$SeF$_6$ gas time projection chamber (TPC). Direct charge collection for the drifting ion charge carriers using low-noise CMOS charge sensors is the main feature of the experiment.
