The nuclear phase diagram is mapped using beam energy scans of relativistic heavy-ion collisions. This mapping is possible because different collision energies develop along different trajectories through the phase diagram. High energy collisions will evolve though a crossover phase transition according to lattice QCD, but lower collision energies may traverse a first order phase transition....
I will report on progress towards a
quantitative first-principle continuum approach to QCD, focusing on
results for quenched QCD and Yang-Mills theory at vanishing and finite temperature obtained in the framework of the Functional
Renormalization group.
In the second part of my talk I will sketch how dynamical questions such as the
calculation of spectral functions or transport...
Currently at the Beam Energy Scan at RHIC experimental efforts are being made to find the QCD critical point. On the theoretical side, the behavior of higher-order susceptibilities of the net-baryon charge from Lattice QCD may allow us to estimate its position via Taylor expansion of the density of states at $\mu_{B}=0$. However, even if the series expansion continues to higher-orders, there...
Bose-Einstein correlations between identified charged pions are measured for p+Pb collisions at √sNN=5.02 TeV with the ATLAS detector with a total integrated luminosity of 28 nb−1. Pions are identified using ionization energy loss measured in the pixel detector. Two-particle correlation functions and the extracted source radii are presented as a function of average transverse pair momentum...
The properties of the quark-gluon plasma have been extensively studied in high-energy nuclear collisions at RHIC. In particular the Beam Energy Scan, a research program capitalizing on RHIC’s unique capability to vary the collision energy from 7.7 to 200GeV, presents an unprecedented opportunity to study the phase diagram of the strongly interacting matter.
Femtoscopic measurements of...
Using hadronic many-body theory, the author calculates the rho meson self-energy in a pion gas. Previously the effects of in medium nucleons and delta particles (which have a large coupling to the rho) on the rho propagator, have been calculated. However the effects of in-medium pions were not included. Calculation of the electric conductivity requires one to consider the zero momentum and...
